Canadian Infrastructure Report Card

The second Canadian Infrastructure Report Card (CIRC) was released in January 2016. The initiative was sponsored by the Federation of Canadian Municipalities (FCM), the Canadian Construction Association (CCA), the Canadian Society for Civil Engineering (CSCE) and the Canadian Public Works Association (CPWA). The 2016 CIRC reports on potable water, storm and wastewater systems, roads and bridges, building, sport and recreational facilities, and public transit. The CIRC provides comprehensive, scientifically based, and standardized information on the inventory, condition and asset management practices of Canada’s core public infrastructure. It is intended to inform infrastructure planning, design and management activities completed by the various stakeholders of Canada’s infrastructure systems, including policy-makers and asset owners. The CIRC indicates that one-third of our municipal infrastructure is in fair, poor or very poor condition, increasing the risk of service disruption. The CIRC also indicates that reinvestment rates are not sufficient to stop the decline in the state of our infrastructure systems. The first part of the presentation provides a detailed overview of the CIRC process and results. The second part provides some ideas generated through a collaborative effort of CSCE’s members to leverage planned infrastructure investments to make our infrastructure systems more sustainable.

The use of geomembranes for lining canals

This keynote lecture will present the state of the art on the use of geomembranes (often associated with other geosynthetics) for canal lining. Numerous case histories of geomembrane-lined canals from various parts of the world, in particular the Middle East, will be presented. These cases, spanning four decades from the 1970s to date, include large canals as well as small canals, which play an important role in irrigation schemes. Also, the case histories will include the rehabilitation of old concrete-lined canals. The focus will be on irrigation canals; however, examples of hydroelectric canals lined with geomembranes will be mentioned, because the considerable experience gained on hydroelectric canals is likely to be beneficial to the design and construction of irrigation canals. The case histories will show that flexible linings with very low permeability are the only viable option in some climatic conditions (e.g. freeze and thaw) and soil conditions (soluble soils containing gypsum, collapsible soils such as loess, and swelling clays). The case histories presented illustrate the use of a variety of geomembranes in canals (e.g. PVC geomembranes, HDPE geomembranes, EPDM geomembranes, bituminous geomembranes, geotextile-geomembrane composites). Design methods related to the use of geomembranes in canals will be discussed, in particular: drag forces exerted by flowing water on geomembrane liners, uplift of geomembranes by dynamic pressure of the flowing water, bridging of cracks by geomembranes, stability of protective layers on the side slopes. The need for protection of geomembrane liners will be addressed and the following protection techniques will be discussed: concrete slabs, cast-in-situ concrete, soil layers, cobbles, gabions, fabric-formed concrete panels, geocells, articulated concrete blocks, etc. Finally, the performance of geomembranes in canals will be addressed and compared with the performance of traditional concrete linings.

Effects of Horizontal and Vertical Stress Relief on the Capacity and Deformation of Friction Piles

To efficiently use of underground space for meeting increasing infrastructural needs while minimizing environmental impacts, a significant number of tunnels and ever deeper basements are being excavated in densely populated cities like London, Shanghai and New York. Practising structural and geotechnical engineers are facing tougher and tougher design challenges. In this keynote lecture, the effects of stress relief due to deep excavation and twin tunnelling on the capacity and deformation of friction piles are discussed. In the first part of the lecture, centrifuge model tests carried out to investigate the capacity and deformation ofa friction pile with and without considering vertical stress relief due to a -20m deep basement excavation are reported. For comparison purposes, in-flight pile load tests were conducted both at the ground surface and at the formation level after an in-flight simulation of the excavation. A non-dilatant pile-soil interface was adopted for simulating piles installed in normally consolidated clays and loose sands, whereas a dilatant pile-soil interface was used for modelling piles constructed in overconsolidated clays and dense sands. In addition, discrete element modelling (DEM) of these two pile-soil interfaces was carried out to reveal the governing mechanisms and the changes in pile shaft resistance. A simple calculation method allowing for the effects of vertical stress relief on pile capacity is then proposed. In the second part of the lecture, a series of three-dimensional centrifuge model tests and numerical back-analyses are reported to study the influence of twin tunnelling on an adjacent friction pile and pile group. Moreover, the effects of the construction sequence of twin tunnelling on an existing pile are explained. Design implications of these two types of stress relief (i.e., vertical and horizontal) on piled foundations are highlighted. HONORS LECTURES PROFESSOR Abdel-Ghaffar

Abdel-Ghaffar’s1974 investigation of the dynamic characteristics of the Vincent Thomas Bridge in Los Angeles, done when he was a graduate student, led to new standards on how to collect, analyze and interpret structural dynamic measurements from complex, three-dimensional, extended structures. His investigation allowed the development of high-fidelity computational tools used to reliably design such structures to resist the action of earthquake ground motion. The California Department of Transportation (Caltrans) used Abdel-Ghaffar’s computer program when it embarked on a major retrofit of the Vincent Thomas Bridge, and he served as a consultant, determining the damping characteristics of the bridge.

“Professor Abdel-Ghaffar’s excellence and innovation in the area of long span bridges was known internationally and he was much beloved by his students,” said Yannis C. Yortsos, dean of the USC Viterbi School of Engineering. “He is greatly missed by all of his colleagues here and around the world.”

«Building tall bridges that span engineering frontiers and withstand great earthquakes was Ahmed Abdel-Ghaffar›s passion. Ahmed was a gentleman engineer and a dedicated educator,» said Jean-Pierre Bardet, chair of the USC Sonny Astani Department of Civil and Environmental Engineering where Abdel-Ghaffar was on the faculty.

Abdel-Ghaffar also made major contributions to understanding and analyzing the behavior of structures interacting with soil during earthquakes. He was among the pioneers who conducted forced-vibration experiments on the Santa Felicia Earth Dam and interpreted its recorded seismic and dynamic response.

A meticulous writer with an eye for detail and eloquence, he was a gifted and dedicated teacher whose lecture notes continue to be used today by his students many of whom are professors at academic institutions worldwide.

A native of Egypt, Abdel-Ghaffar graduated in1970 from Cairo University with a B.S. degree in civil engineering. He was the class valedictorian, earning a “first class honors” distinction. After working for two years as an instructor in structural engineering at Cairo University, he attended the California Institute of Technology, where he earned a master’s degree in civil engineering in 1973 and a Ph.D. with an emphasis on structural dynamics and earthquake engineering in 1976. His reputation at Cairo University as one of the most intelligent and attentive young lecturers led other aspiring Egyptian researchers to follow him to the United States.

Abdel-Ghaffar’s pioneering research at Caltech as a doctoral student under Prof. George Housner broughthim international recognition in the then-emerging field of sensor-based monitoring of long span flexible bridges.

In 1978 Abdel-Ghaffar joined the Materials Engineering Department at the University of Illinois at Chicago-Circle and he moved to the Civil Engineering and Engineering Mechanics Department at Princeton University as an assistant professor the following year. He came to USC in 1987 as a full professor.

He served as a consultant to government agencies in the U.S., Japan, Europe, the Middle East, and elsewhere. Among Abdel-Ghaffar’s many notable projects, was one to monitor vibration of the Golden Gate Bridge and hehunga breathtaking photograph in his office showing him and his students standing near the top of the bridge while collecting sensor data.

During his long illness, he continued to interact from his bed with a number of international contacts and provide valuable advice on many projects, such as the long span bridge across the Gulf of Suez. Abdel-Ghaffar, a resident of Rolling Hills Estate, was survived by his former wife and three children. SPEAKER

BIOLOGICAL CEMENTATION OF UNSTABLE SOILS AND GROUNDS FOR CIVIL INFRASTRUCTURE DEVELOPMENTS Geotechnology and Sustainable Pavement Solutions

Problematic soils (e.g. loose, erodible and collapsible) are widespread in the world and greatly hinder infrastructure developments. Such unstable soils pose significant challenges to the geotechnical engineering communities due to their low bearing capacity and high compressibility, causing severe damages to civil engineering structures such as building foundations, roads, retaining walls, etc. Engineered ground improvement is often necessary to increase soil load-carrying capacity and prevent excessive post-construction deformations. However, existing techniques of ground improvement can be highly expensive (e.g. pile foundations) and some have significant environmental, sometimes toxic effects (e.g. chemical stabilisation by Portland cement). In this presentation, an innovative technology for ground improvement, through biologically induced cementation, will be presented and discussed. This technology uses a bacteria-driven process that results in calcite precipitation, which mimics the natural digenesis from sand to sandstone or lime to limestone, only within a short time instead of million years. The technology is eco-friendly and sustainable, and is expected to replace most conventional soil stabilisation methods, for superior urban and coastal infrastructure developments. PROFESSOR Harry Poulos

Professor Harry Poulos› pioneering work in pile foundation analysis and design has enabled the world›s geotechnical specialists to have a greater understanding of the way structures interact with the ground. His research has enabled a more reliable approach to be adopted for pile design, replacing procedures which previously relied purely on experience and empiricism. Professor Poulos has applied his research to a wide range of major projects, both in Australia and overseas, including buildings, bridges, tunnels, freeways, mines, airports offshore structures (e.g. oil rigs) and earthquake-related problems. Professor Poulos› work includes the Emirates Twin Towers in Dubai, where his analysis and design of the piled raft foundations provided significant cost benefits for the twin towers exceeding 300 metres in height, the Burj Khalifa, now the world›s tallest building, where he was the geotechnical peer reviewer, the Docklands project in Melbourne involving design of remedial pile foundations for one of the high rise residential developments, and the construction of a 700km long motorway in Greece using his expertise in slope stabilisation and earthquake engineering. While retaining his professorial position at the University of Sydney, Professor Poulos joined the Coffey Group in1989, as the Director of Advanced Technology, and became Chairman of Coffey International Pty Ltd in 1991, a position that he held for two years. In the period 1998 to 2002 he served as Director of Technical Innovation and General Manager, Technical Development. Professor Poulos has long been a contributor to the activities of the international geotechnical community. He was also a long-term member of the National Committee of the Australian Geomechanics Society (AGS) (1980 to 1995) and its Chairman from 1982 to 1984.

FIFTY YEARS OF RESEARCH AND PRACTICE FOR PILE FOUNDATIONS

Starting from the pioneering papers published in 1968 by Poulos dealing with single pile and pile groups, significant advances have been made in field of pile foundations. New pile types, improved method of analysis and more rational design approaches are now available for practical purposes. Thanks to the availability of powerful computers and numerical analysis tools, we are now in the position to investigate very complex problems (geometry; loading conditions; material properties, etc.). However, all calculations, no matter how sophisticated and complex, cannot be more than rough approximation of the natural phenomenon they try to represent by means of a model. It follows that it is fundamental to check the outcomes of complex models and/or analyses with more simple methods, where possible. When this methodological approach has been followed, significant advances have been registered in approaching pile problems. In the presentation, a tentative is made to “align” those fundamental steps which made possible significant advances in the field in the last50 years (2018-1968). PROFESSOR

Dealing with Rock Falls in Inhabited Areas

Among the “Grand Challenges for Engineering”, identified by the Expert Committee of the NAE (National Academy of Engineering), one may point out the Impact of rock slopes instabilities on people, man-made infrastructures, and inhabited areas. In relation to this, very important are rock falls that may pose a significant threat on inhabited areas located immediately down-slope. It is to be highlighted that rock falls are a major cause of landslides fatalities. The purpose of the present lecture is to illustrate first typical rock fall problems with examples taken from practice and personal experience. Advanced and novel investigative methods to study and characterize the rock mass in detail and define the likely modes of rock instability initiation and failure will be considered. Then, the attention will be dedicated to the three-dimensional modelling of the rock fall process down-slope. Two case studies of high, steep, and jointed limestone rock cliffs in Italy, characterized by the presence of rock volumes of different shape and size, in limit equilibrium conditions, are described in detail. It is highlighted that in both cases the rock volumes when detached from the cliffs, following a series of leaps and bounds down slope, may reach and damage town houses located at the slope toe. The studies for analyzing the rock cliff stability conditions are presented together with the kinematic simulations of the rock falls down slope considered, also with the intent to find the type and location of the passive measures to be implemented. Depending on the source of instability, being it localized or distributed along the cliff, studies of the structurally controlled mechanisms (e.g. plane and wedge sliding and/or toppling) were undertaken by using Conventional Mapping and Terrestrial Laser Scanning methods.

Dr. Desai’s research contributions have received outstanding recognitions at national and international levels, some of which are indentified as: (a) development and applications of finite element method for problems involving interaction between structures and foundations, (b) the thin-layer interface element for simulation of contacts (interfaces and joints), (c) the Residual Flow Procedure for free surface seepage (d) a novel fundamental approach for microstructural instability including liquefaction, and (e) the disturbed state concept for modeling of engineering materials and interfaces, including thermo-mechanical and rate dependent behavior of materials in electronic chip-substrate systems.

Constitutive Modeling of geologic materials and interfaces Significant for Geomechanics

Behavior of geologic materials, interfaces and joints play the vital role for realistic and economical solutions for geotechnical problems under mechanical and environmental (fluid, thermal, chemical, electromagnetic, etc.) loadings. Characterization of the behavior, refereed as constitutive modeling, requires appropriate basic mechanics and physics, testing (laboratory and field), determination of parameters, validations at the specimen level and at boundary value problem level. A brief review of available constitutive models will be followed by a description of the unified Disturbed State Concept (DSC). Material behavior involves simultaneous occurrence of factors such as elastic, plastic and creep deformations, volume change, stress path effects, microstructural modifications leading to cracks, fracture, failure, liquefaction, softening or degradation and healing or strengthening. Most available models allow for specific number of these factors, while unified models are desired that allow for, as necessary, simultaneous occurrence of the foregoing factors. The DSC with the hierarchical single surface (HISS) plasticity provides for such unique and versatile unified model. A number of examples problems involving testing and modeling of a wide range of materials and interfaces like sand, clay, rocks, asphalt, concrete, alloys, silicon involving mechanical, thermal, fluid and chemical effects will be presented. Solutions and validations for practical problems involving laboratory and field measurements using computer (finite element) procedure with the DSC/HISS will be presented. They would include challenging problems in geotechnical, ground improvement, transportation (pavement), earthquake and liquefaction, underground works, seepage and consolidation, composites (electronic packaging), and motion of glaciers and ice sheets. The importance of appropriate constitutive modeling for realistic solutions in Geomechanics and general engineering cannot be overemphasized. PROF. DR. ENG. Pierre DELAGE

On the Thermal Behaviour of Clays and laystonesC

Particular attention has been paid for some time to thermal issues in soils and rocks, with respect to the storage of high activity exothermic radioactive waste at great depth. This field also concerns various Geo-energy issues, like the behaviour of thermal piles, heat storage in the ground, the burial of high voltage cables, non-conventional oil production and ground-atmosphere interactions. Whereas advanced in-situ experiments have been carried out in some underground research laboratories excavated in clays and claystones in Belgium, France and Switzerland, rather few laboratory data about the thermo-hydro-mechanical behaviour of claystones are available in the literature. Thermal testing of clay rocks actually requires adopting some soil mechanics concepts, concerning in particular saturation procedures and drainage conditions. Based on the use of specifically developed novel experimental devices, new data concerning the thermo-poro-elastic characteristics, the thermal volume changes (with special interest devoted to plastic thermal contraction), and thermal pressurisation issues in various clays and claystones from Belgium (Boom clay), France (Callovo-Oxfordian claystone) and Switzerland (Opalinus Clay) are presented. These new data are of significant importance in the assessment of the stability and long-term performance of radioactive waste disposal systems in clays and claystones. PROF. DR. ENG. M.

Geo-Structural Nonlinear Analysis of Piles

Pile foundations are utilized to support a variety of important infrastructure where they are subjected to static and/ or dynamic lateral loads due to lateral earth pressure, vessel impacts, traffic, waves, wind, and earthquakes. The pile lateral behavior under extreme lateral loading is governed by two main factors: the interaction between the pile and surrounding soil; and the material inelasticity of the pile itself. This presentation covers the state-of-the-art of modeling the nonlinear response of piles. In addition, it describes the recent development of an efficient and robust approach for the analysis of piles based on the Beam on Nonlinear Winkler (BNWF). In this work, a general cyclic BNWF model is developed to account for the important features of soil-pile interaction problem including lateral load characteristics, soil cave-in, soil-pile side shear, gap formation, and strength and stiffness hardening/degradation. The inelastic behavior of pile material is also modeled effectively by implementing the advanced fiber technique. The capability of the developed model in predicting the response of piles under lateral static, cyclic and seismic loading is validated by comparing the computed results with experimental data. PROF.

Coupled Fire and Earthquake Analysis of Steel Buildings

Fire following earthquakes has caused very significant damage and loss of life in previous earthquakes. This presentation introduces an analysis environment that provides versatile and realistic assessment of the combined earthquake and fire effects on steel building frames. The advanced inelastic dynamic analysis platform ZEUS-NL is extended to conduct thermal stress analysis after large deformations and damage have been suffered by the structure. The deformed shape at the end of the earthquake is used as the initial condition for subjecting the structure to non-uniform temperature gradients that are varying with time. This second analysis may also be followed by another dynamic analysis under the effect of earthquake aftershocks. Examples of application are provided from previous earthquakes aswell experimental investigation. The tool presented is an open-source advanced analysis code that is available for use worldwide.

I.M. Idriss, a UC Davis professor emeritus of geotechnical engineering, was on the second floor of a San Francisco high-rise when the 6.9 magnitude Loma Prieta earthquake struck on Oct. 1989 ,17. As colleagues dove for cover beneath a conference table, Idriss stood in a doorway … where he had a perfect view of buildings swaying in response to the forces he had studied throughout his career. “Each earthquake tells us a story,” Idriss explained, during an interview given on the 20th anniversary of this catastrophe. “Sometimes it confirms something we know, or sometimes it tells us something we didn’t know.” In the wake of the Loma Prieta quake, Idriss was one of eight people named to Gov. George Deukmejian’s Board of Inquiry; the panel was assigned to find out why the Cypress section of I880- and a section of the San Francisco-Oakland Bay Bridge had failed … and how the state could prevent this from happening again. Idriss and his fellow panel members eventually recommended that all of the state’s approximately 24,000 bridges be inspected for quake-worthiness and — if necessary — retrofitted. Following this inquiry, Idriss and several other UC researchers continued to work with Caltrans, serving on the state’s Seismic Advisory Board and on peer advisory panels for all the Bay Area toll bridge retrofit projects. Idriss has spent half a century studying how soils react to the shaking that occurs during an earthquake. During that time, his geotechnical advice has been sought by government agencies and advisory panels around the world. He has been involved with the follow-up analysis of every major earthquake since the 1964 Alaska quake, including those at San Fernando, Mexico City, Northridge and Kobe; he has been part of the team of engineers that descends on a region in the aftermath of a major quake, to analyze damage and determine causes of structural collapse. Loma Prieta was, however, the only quake he experienced in person. His research on soil mechanics and foundation engineering has influenced the construction of dams, nuclear power plants, seaports, office buildings, residences, hospitals, railways and bridges around the world. In 1999, Idriss received a UC Davis Distinguished Public Service Award, an honor that recognizes faculty members who have made public service contributions to the community, state, nation and world throughout their professional careers. This followed his 1989 election to the National Academy of Engineering, and the many high honors he has received from the American Society of Civil Engineers. Recognizing the value of such awards, Idriss subsequently established one himself: the UC Davis Prize for Excellence in Geotechnical Engineering — now known as the Idriss Award — which recognizes a graduate student’s achievements in outstanding scholarship, leadership and fellowship.

Application of Geo-inclusions for Sustainable Rail Infrastructure under Increased Axle Loads and Higher Speeds

Given the increasing demand for faster trains for carrying heavier loads, current ballasted railroads require considerable upgrading. As a response, this keynote reflects the state-of-the-art developments in track geomechanics, based on large-scale laboratory tests, computational modelling and field measurements where improved performance of ballast by geosynthetics (e.g. geogrids and geocells), as well as energy-absorbing rubber mats and infilled recycled tyres is examined. Full-scale monitoring of instrumented tracks supported by rail industry has been carried out, and the field data obtained for in situ stresses and deformations could verify the track performance, apart from validating the numerical simulations. This presentation will also focus on the role of geo-inclusions in reducing ballast degradation and subgrade soil fluidization through R & D innovations from theory to practice, facilitating enhanced rail design and construction principles to cater for higher speeds and heavier freight.

DESIGN OF ENERGY GEOSTRUCTURES

This study proposes an analysis of the multiphysical phenomena governing the thermo-mechanical behaviour of energy piles. The analysis is based on the results of a series of full-scale in-situ tests, laboratory experiments and numerical analyses. First, the thermo-mechanical behaviour of energy piles is considered. Attention is given to both single and groups of energy piles. Next, the response of soils and concrete-soil interfaces subjected to temperature changes is reviewed. The behaviours of clayey soils in different overconsolidation states as well as of both concrete- sand and concrete-clay interfaces are analysed. Finally, aspects considered of paramount importance for the analysis and design (e.g., geotechnical and structural) of energy piles are presented. Both floating and end-bearing energy piles are investigated. The goal of this paper is to increase the confidence of civil engineers on the performance of energy piles. PROF. DR. ENG.

MODERN DESIGN APPROACH FOR LANDFILL LINERS

The design of landfill bottom barrier systems on the basis of their performances requires the modelling of the pollutant transport processes, while taking into consideration both advective and dispersive-diffusive phenomena. This modelling can be developed in the context of an environmental and health risk assessment, which allows the specific vulnerability of the site to be taken into account. A calculation procedure, based on closed-form analytical solutions, which can be considered suitable for a second-level risk analysis type, according to the ASTM and USEPA classifications, is presented in this paper. This procedure, although based on a very simple and intuitive conceptual model, is able to provide useful indications for design choices, at least in the preliminary dimensioning phase of a project.

Fibre reinforcement of railway ballast

It is known that the addition of randomly placed fibres can improve the strength and ductility of granular materials such as sands. The talk will discuss recent developments in the application of the technique to railway ballast, including monotonic and cyclic triaxial tests on scaled reinforced ballast establishment of an appropriate mechanical framework to explain the observed behaviour tests on full size railway ballast in a full-width sleeper bay, carried out in the Southampton Railway Testing Facility, and initial results of a full-scale field trial. The mechanical behavioural framework is based on a consideration of the additional effective stress applied to the granular skeleton as tensions in the fibres develop; and the laboratory tests are used to assess suitable relative fibre to grain dimensions and proportions, and to optimise the fibre shape. The approach is shown to have the potential to reduce the development of plastic track settlements, and hence maintenance needs. PROF. DR. ENG. Anand J. Puppala

Ettringite Induced Heaving in Stabilized High Sulfate Soils

Stabilization of expansive soils using lime and cement additives have been used by practitioners over the years. However, recent heaving and premature pavement failures in lime and cement-treated subgrades containing sulfates led to questioning the validity of calcium based stabilization. When expansive soils containing sulfates are treated with calcium-based stabilizers, the calcium from the stabilizer reacts with soil sulfates and alumina to form the expansive mineral Ettringite. Formation and growth of the mineral Ettringite has been reported as the cause of severe heaving in several pavement failures. Under certain environmental conditions, Ettringite transforms itself into another expansive mineral, Thaumasite. This mineral is also known to induce significant soil heaving. Annually millions of dollars are spent to repair pavements distressed by this ettringite induced heaving. Several theories have been proposed to understand the heaving mechanisms in sulfate bearing soils. Based on the theoretical background, researchers and practitioners have proposed various methods to treat sulfate soils. Applicability of these methods is mostly limited to soils containing sulfate content less than 8,000 ppm. Soils with sulfate content above 8,000 ppm are termed as ‘high sulfate’ soils, and chemical treatment of such soils is currently not considered. A research study was designed to aid in understanding the heaving phenomenon in soils with sulfate contents above 8,000 ppm and to develop practical techniques to sabilize such soils. Six soils: four high plasticity clays, one low-plasticity clay soil and one high-plasticity silt, with sulfate contents varying from 200 ppm - 44,000 ppm, were considered for this research. Chemical and mineralogical tests were performed on the untreated soils to establish the clay mineral distribution and composition of the soils. The present high-sulfate soils were treated with lime stabilization with varying mellowing periods and treated soils were then subjected to the engineering and chemical tests. Tests results were analyzed to understand the effectiveness of mellowing period on the heaving phenomenon of ‘high sulfate’ soils. Both Ettringite formation and crystal growth have contributed significantly to the overall swell of the treated soils. Swell trends observed in the treated soils at respective mellowing periods were attributed to the variability in sulfate levels and reactive alumina and silica contents. Treated soils at higher mellowing periods showed lesser sulfate induced heaving when sulfate levels are lesser than 30,000 ppm. At higher sulfate levels, the mellowing did not result in effective treatment of soils. It was also observed that compaction void ratios and soil clay mineralogy have a significant impact on the swell behavior of chemically treated high-sulfate soils at different mellowing periods. This keynote paper provides a comprehensive review of stabilization of high sulfate soils and methods studied to mitigate sulfate heaving in them. PROF. DR. ENG. Peter Robertson

CPT-based Soil Behavior Type (SBT) Classification System

Geotechnical engineers use classification systems to group soils according to shared qualities or characteristics based on simple cost effective tests. The most common soil classification systems used in geotechnical engineering are based on physical (textural) characteristics such as grain size and plasticity. Ideally, geotechnical engineers would also like to classify soils based on behavior characteristics that have a strong link to fundamental in-situ behavior. However, existing textural-based classification systems have a weak link to in-situ behavior since they are measured on disturbed and remolded samples. The cone penetration test (CPT) has been gaining in popularity for site investigations due to the cost effective, rapid, continuous and reliable measurements. The most common CPT-based classification systems are based on behavior characteristics and are often referred to as a Soil Behavior Type (SBT) classification. However, some confusion exists since most CPT-based SBT classification systems use textural-based descriptions, such as sand and clay. The presentation will provide an update of popular CPT-based SBT classification systems to use behavior-based descriptions. The update includes a method to identify the existence of microstructure in soils and examples are used to illustrate the advantages and limitations of such a system. PROF. DR. ENG. Helmut F.

Examples of successful numerical modelling of complex geotechnical problems

Over the last decades numerical methods have gained increasing importance in practical geotechnical engineering and it can be stated that numerical methods have become a standard tool in geotechnical design, widely accepted by the geotechnical profession. The advantages of numerical analyses for solving practical problems has been recognized and developments in software and hardware allow their application in practice with reasonable effort. However, there is still a gap between practice and research and, often unnecessary, oversimplifications are still made in practice and therefore the full power of numerical analyses is not always utilized. One reason for this discrepancy is a lack of transfer of knowledge from research to practice but also a lack of theoretical background of numerical methods, constitutive modelling and modern soil mechanics in practice. In this paper the application of advanced numerical models for solving practical geotechnical problems is shown whereas the examples have been chosen in such a way that different aspects are highlighted in each case. Results from fibre-optic measurements for a pull-out test of a ground anchor in soft soil could be reproduced by employing advanced constitutive models, in particular for the grout, in the bonded length of the anchor. For this test a class-A prediction has been made and numerical results have then been compared with in-situ measurements. The back-analysis of a slow moving landslide is presented where the rate of deformation is influenced by water level changes in a reservoir for a pumping power plant, creep of lacustrine sediments and environmental effects such as rainfall infiltration. Finally some results of modelling cone penetration testing in silts are presented highlighting the effects of anisotropic permeability and partial drainage. PROF. DR. ENG. Charles D. Shackelford

Sustaining Chemical Containment with Enhanced Bentonite-Based Barriers

Engineered bentonite-based barriers are often used to contain chemicals waste streams. Examples of these barriers include soil-bentonite vertical cutoff walls, compacted mixtures of bentonite and other natural soil, usually sand, geosynthetic clay liners comprising bentonite sandwiched between two geotextiles, and highly compacted bentonite buffers used for radioactive wastes. The use of bentonite in these barriers stems form the ability of the bentonite to swell upon hydration, thereby producing a low hydraulic conductivity. Although these barriers generally are able to attain a suitably low saturated hydraulic conductivity (typically < 1x11-10 m/s) based on permeation with water or dilute chemical solutions, permeation of these barriers with more concentrated chemical solutions typically representative of practical applications can result in adverse interactions between the bentonite and chemical solutions resulting in unacceptably high hydraulic conductivities. As a result, significant study is being undertaken to evaluate the use of enhanced (e.g., chemically modified) bentonites as substitutes for traditional bentonite in bentonite-based barriers to both enhance and sustain chemical containment. This presentation summarizes the results of studies focused on determining the effects of chemical modification on the primary engineering properties that govern flow and transport through enhanced bentonites, including hydraulic conductivity (k), the effective diffusion coefficients (D*), and the membrane efficiency or chemico-osmotic efficiency coefficient (w). Enhanced bentonites generally exhibit superior transport properties (lower k, lower D*, higher w) when subjected to solutions with elevated chemical concentrations. However, exceptions exist, and the improved engineering behavior of an enhanced bentonite may not always be sustainable. Based on the results, several mechanisms governing the behavior of enhanced bentonites are hypothesized. DR. ENG. Alberto M. Scuero

Lecture Title: Geomembranes saving waters in reservoirs and canals PROF. DR. ENG. Alan Keith Turner

Emeritus Professor of Geological Engineering, Colorado School of Mines

As a faculty member at the Colorado School of Mines since 1972, Dr. Turner’s research has concentrated on how computers and spatial information technologies can impact geological, engineering, hydrogeological, and environmental studies, and how such new applications can influence society at large. Following a 1988 sabbatical research visit to the Netherlands, he has pioneered 3D subsurface geological modeling, beginning with serving as chairman of a NATO-sponsored Advanced Research Workshop in Santa Barbara, California, the first international conference devoted to 3D Modeling and Geoscientific Information Systems. This research continued in the USA in connection with the proposed Yucca Mountain nuclear waste repository and at a series of European conferences. These research interests resulted in Dr. Turner’s appointment as Chair in Engineering Geology at Delft University of Technology in The Netherlands (2002-1999), where he gained experience with geological and geotechnical engineering challenges resulting from proposed new uses of underground space and in 2001 chaired a European Science Foundation Conference “New Paradigms in Subsurface Prediction” at Spa, Belgium. Current research interests include the use of new sensor technologies and web- based information management and collaboration procedures for geological hazard analysis and risk assessment.

Social and Environmental Impacts of Landslides

The term “landslide” defines the “movement of a mass of rock, debris, or earth down a slope.” However, landslides are not limited either to the “land” or to “sliding.” Landslides are natural phenomena that cause societal disruptions when humans place parts of the built environment in their path. Slope instability along transportation routes and in mountain valleys pose dangers and are a source of considerable economic losses. Landslide velocities vary over ten orders of magnitude from “extremely slow” to “extremely rapid.” Large numbers of fatalities can be expected from “very rapid” and “extremely rapid” landslides which move faster than a person can run. In contrast, buildings on “very slow” and “extremely slow” landslides may remain in use for hundreds of years with only minimal damage and repair costs. The volumes of landslides similarly range over many orders of magnitude. The product of landslide volume and speed approximates its “power” (or energy). It is a useful measure of the destructive potential of landslides. Landslides are local events; even the largest and most spectacular landslides exist “under the radar” and rarely result in national disaster declarations. Landslide losses include “direct” and “indirect” costs. “Direct costs” are damages directly attributable to the landslide. “Indirect costs” include travel detours, economic restrictions, and environmental impacts. Indirect costs often equal or exceed the direct costs. Activities that prevent or reduce the adverse effects of landslides are termed “mitigation.” Mitigation includes structural and geotechnical measures, as well as political, legal, and administrative measures to protect endangered populations. Reducing the global impact of landslides on risk-prone populations and critical infrastructure is an economic, social, and environmental necessity. Loss data show that, while losses are increasing everywhere, the consequences are much higher in developing countries than in developed countries. M.SC Serge VARAKSIN

The State of Practice of In-situ Tests for Design, Quality Control and Quality Assurance of Ground Improvement Works

In the state of the art report that was published on ground improvement processes at the 17th International Conference on Soil Mechanics and Geotechnical Engineering in 2009, ground improvement was defined in five categories of which the first three included non-structural techniques without or with non-grout inclusions. This paper will focus on these categories techniques and the most common in-situ geotechnical tests that are used during the geotechnical investigation, quality control and quality assurance phases; i.e. the cone penetration test, standard penetration test, pressuremeter test and dilatometer test. In addition to the suitability and feasibility of the technique itself, the level of success of any ground improvement programme is also related to the applicability and suitability of the criteria that is to be satisfied and the testing campaign that is to be undertaken to verify the works. Whilst there are numerous ways to define the targets of improvement, experience of the authors indicates that the optimal approach is when acceptance is based on the project’s actual geotechnical requirements rather than on minimum test results. At the same time, ground improvement design parameters can only be properly determined when the ground conditions are correctly comprehended, which is possible through meaningful geotechnical investigation. Similarly, applied treatment can only be confidently verified when testing is able to well relate to acceptance criteria. Hence, tests that are able to predict the acceptance criteria without reliance on experimental correlations and published work from other sites will result in the best engineering practice and confidence is results.

Towards Sustainable Geotechnical Engineering

Today, the global awareness of preservation of the environment has become the focal point of many human disciplines. Much of the emerging scientific and engineering efforts are being directed to maintain the harmony between new developments and the important three E’s: Environment, Economy and Equity. Such studies are essentially needed in response to the rise in atmospheric carbon dioxide, global warming, rapid depletion of natural resources and other similar ecological hazards and it is from this context that sustainable engineering came to life. Sustainable engineering aims at ensuring the well-being of the current and future generations with sustainable geotechnics, as a sub-discipline within engineering, covering a wide range of topics related to the sustainable development of civil engineering infrastructure and society. Sustainable geotechnics deals with material recycling, and the utilization of geothermal renewable energy and alternate materials in geotechnical engineering constructions. In this paper, a brief overview of this sub-discipline of geotechnical engineering is presented aiming at connecting the broader scope of sustainability to traditional geotechnical research and practice.

Advanced Numerical Modeling of Large Deformation Analysis for Geotechnical Problems

Modeling of large deformations were always a challenging task in geotechnical engineering. Numerical modeling of such issues is usually complex and tricky. The basic problem of modeling such situations is insufficient formulation of the classical Finite Element Method (FEM). Mesh distortions that accompany Lagrangian approaches effectively prevent engineers from obtaining reliable solutions. To overcome the problems accompanied by the large deformations, new types of formulations were proposed during last decades, such as the Arbitrary Lagrangian-Eulerian (ALE) method; the Smoothed Particle Hydrodynamics (SPH) and the Coupled Eulerian-Lagrangian (CEL) method. The basic concepts and features of these methods are shown. Then, applicability of the CEL method for different geotechnical problems will be investigated. The coupled Eulerian-Lagrangian method (CEL) combines both Eulerian and Lagrangian formulations to analyse complex problems including large deformations, which are generally not feasible with conventional finite element methods. The geotechnical application of the CEL method models the soil domain with Eulerian elements and solid structure with Lagrangian elements and defines the interface of both materials on the boundary of the Lagrangian body. Then the Lagrangian body can be pushed into the soil Eulerian body which is allowed to flow around the Lagrangian body with no mesh distortion. The first problem involves the penetration of Spudcan, which are used as foundations providing a secure operation of mobile jack-up rigs, into layered subsoil using nonlinear finite element program (ABAQUS) . Spudcans usually have diameters between 10 m and 16 m, but anyway the diameter steadily increased in recent decades and sometimes exceeds 20 m and the penetration is about three times the spudcan diameter. Parametric study will be presented to examine the overall characteristics of spudcan penetration. The numerical results were validated against real measurements and different analytical solutions. The second problem deals with the numerical simulation of vane shear tests in cohesive soils using three dimensional numerical model with the coupled Eulerian-Lagrangian (CEL) method. Mobilization of shear stress on the vertical and horizontal surfaces of the vane is studied. Also, the shear stress and rotational moment results obtained from the FE analyses have been compared with the measured real-field experimental data. The third problems is mainly focused on the modeling of cone penetration testing (CPT). The soil stress–strain response has been simulated using the Mohr–Coulomb constitutive model. The cone is modeled as a rigid body in the simulations. The results of CEL simulations have been compared with the laboratory and field test results. It is observed that CEL can successfully simulate cone penetration tests which in turn, facilitates in characterizing soil stress–strain response. Finally, recommendations regarding further investigations are given. PROF. DR. ENG. Yasser El-Mossallamy

How to Improve Exchanges between Academic Knowledge and Daily Practice?

Yasser El-Mossallamy Gerhard Schulz and Otto Heeres The rapid development in the last decades all over the world leads to the need of complex infrastructure projects as well as more and more high-rise buildings in complicated geotechnical conditions. Therefore, applications of highly sophisticated site investigation, design procedures applying complex numerical analyses and monitoring programs are now daily work of geotechnical engineers. New engineering generation are asked applying sophisticated numerical analyses to solve all geotechnical problems facing them during the design and construction of complicated structures. The interaction between the required enhanced theoretical knowledge with the appropriate methodologies for engineering applications is a big challenge for the young engineers. The objective of this paper is to show the interaction between Academic Knowledge and Daily Practice regarding complicated and enhanced numerical analyses and real applications to reach the most economic design with minimum risks and also to optimize the required geotechnical solutions for some geotechnical applications. Design of deep pit excavation as well as tunnel projects in complex geological conditions, huge sliding problem that takes place during construction of infra-structure projects and optimization of deep foundation of high rise buildings will be presented and illustrated as some practical examples of how sophisticated academic knowledge can be applied in complex megaprojects. Keywords: Deep pit excavation, tunnels, huge sliding, high rise building, complicated geotechnical conditions, monitoring, numerical analyses. WORKSHOPS 1. CIVIL STRUCTURAL Health Monitoring

Later in 2005, joined Maccaferri India as a ‹Techno-Marketing Engineer› responsible for propagation of the innovative Maccaferri technologies to various prospective Clients and Consultants. Abstract:An engineering approach to the design of Geosynthetics for erosion control on slopes can be based on the well known revised Universal Soil Loss Equation (RUSLE). The use of RUSLE for designing with Geosynthetics requires the definition of the performance of the various products by laboratory and full-scale performance tests. The use of geosynthetics as flexible forms (bags, containers, mattresses and tubes) provide technically sound and economical solutions to many coastal protection problems. The design of Geosynthetics tubes (GST) for coastal protection requires the definition of the required mechanical and hydraulic properties of the geotextiles making the GST, and to perform stability analyses to ensure that the GST structure will not reach ultimate or serviceability limits under the actions of water pressure, waves, gravity. The design methods commonly available for GST in coastal protection applications are presented.

GROUND IMPROVEMENT: Design, Quality Control and Acceptance Testing

The opportunity of materializing the link between the ISSMGE TC 102 (in-situ testing technical committee) and the ISSMGE TC 211 (Ground improvement technical committee) will be offered at the GeoMEast 2018 International Congress and Exhibition in Cairo. One of the terms of reference of the TC 211 is Design, quality control and acceptance testing. The joint effort of booth TC’s became thus a must. The form of “workshop” has been selected by the conference organizer and the Chairs with the respective core members of booth TC’s

They have proposed to call for “extended abstracts”. In fact, extended abstracts will allow contributions from the industry and their experts, usually in difficult position to prepare full articles. A two-pages abstract from the interested participants will be reviewed by the core members of the TC’s. They will have to be addressed to the conference Editorial Manager by September 15th, 2018 http://www.editorialmanager.com/suci

The themes will be closely related to in-situ tests for design, quality control and quality assurance for various ground improvement works

Appropriate lectures addressing the different ground improvement techniques will be selected to develop a 20 minutes contribution. The PowerPoint presentations will be part of an E-Book provided at the workshop

Look forward to welcoming you all to Cairo this November

BASICS OF DESIGN OF Piled Foundations

This one-day event addresses the practice of piled foundation design. What data one must pull together and what processes of analysis and calculations necessary for a design of a specific project are presented. Negative skin friction and associated drag force and downdrag are emphasized along with settlement analysis. Although detailing the various methods and aspects of determining pile capacity, the seminar also shows that deep foundation design is a good deal more than finding some value of capacity and emphasizes how to determine and base a design on the expected settlement. The presentation includes both broad generalities and in-depth details. Specifics of where to install instrumentation, perform a test, and analyze the test data are addressed. Settlement analysis is of vital importance to the design of piled foundations, and the course addresses principles and mechanics of settlement analysis. How to consider and compare straight-shaft piles to piles with changing cross section, e.g., expanded base piles, open- vs. closed-toe pipe piles, is also addressed. Brief comments are given on some Code and Standards requirements for Limit States Design, LSD, (Ultimate Limit States, ULS, and Serviceability Limit States, SLS, by Canadian terminology and Load and Resistance Factor Design, LRFD, by US terminology). The lectures are illustrated with case history examples throughout. Much emphasis is placed on the design and performance of pile groups and piled raft foundations. To simplify following along the flow of the presentation and taking notes, printed hand-out course notes are provided, consisting of all Power Points slides, six to a page. Full-size color copies are available online: [www.Fellenius.net]. The files can be downloaded from the link [/Lectures]. Note, the link is hidden and has to be typed into the command line («command ribbon»).
