  • Soil Plugging of Open-Ended Piles During Impact Driving in Cohesion-Less Soil
    Soil Plugging of Open-Ended Piles During Impact Driving in Cohesion-less Soil VICTOR KARLOWSKIS Master of Science Thesis Stockholm, Sweden 2014 © Victor Karlowskis 2014 Master of Science thesis 14/13 Royal Institute of Technology (KTH) Department of Civil and Architectural Engineering Division of Soil and Rock Mechanics ABSTRACT Abstract During impact driving of open-ended piles through cohesion-less soil the internal soil column may mobilize enough internal shaft resistance to prevent new soil from entering the pile. This phenomena, referred to as soil plugging, changes the driving characteristics of the open-ended pile to that of a closed-ended, full displacement pile. If the plugging behavior is not correctly understood, the result is often that unnecessarily powerful and costly hammers are used because of high predicted driving resistance or that the pile plugs unexpectedly such that the hammer cannot achieve further penetration. Today the user is generally required to model the pile response on the basis of a plugged or unplugged pile, indicating a need to be able to evaluate soil plugging prior to performing the drivability analysis and before using the results as basis for decision. This MSc. thesis focuses on soil plugging during impact driving of open-ended piles in cohesion-less soil and aims to contribute to the understanding of this area by evaluating models for predicting soil plugging and driving resistance of open-ended piles. Evaluation was done on the basis of known soil plugging mechanisms and practical aspects of pile driving. Two recently published models, one for predicting the likelihood of plugging and the other for predicting the driving resistance of open-ended piles, were compared to existing models.

  • Newmark Sliding Block Model for Predicting the Seismic Performance of MARK Vegetated Slopes ⁎ T
    Soil Dynamics and Earthquake Engineering 101 (2017) 27–40 Contents lists available at ScienceDirect Soil Dynamics and Earthquake Engineering journal homepage: www.elsevier.com/locate/soildyn Newmark sliding block model for predicting the seismic performance of MARK vegetated slopes ⁎ T. Liang, J.A. Knappett ARTICLE INFO ABSTRACT Keywords: This paper presents a simplified procedure for predicting the seismic slip of a vegetated slope. This is important Analytical modelling for more precise estimation of the hazard associated with seismic landslip of naturally vegetated slopes, and also Centrifuge modelling as a design tool for determining performance improvement when planting is to be used as a protective measure. Dynamics The analysis procedure consists of two main components. Firstly, Discontinuity Layout Optimisation (DLO) Earthquakes analysis is used to determine the critical seismic slope failure mechanism and estimate the corresponding yield Sand acceleration of a given slope. In DLO analysis, a modified rigid perfectly plastic (Mohr–Coulomb) model is Slopes Vegetation employed to approximate small permanent deformations which may accrue in non-associative materials when Ecological Engineering subjected to ground motions with relatively low peak ground acceleration. The contribution of the vegetation to enhancing the yield acceleration is obtained via subtraction of the fallow slope yield acceleration. The second stage of the analysis incorporates the vegetation contribution to the slope's yield acceleration from DLO into modified limit equilibrium equations to further account for the geometric hardening of the slope under in- creasing soil movement. Thereby, the method can predict the permanent settlement at the crest of the slope via a slip-dependent Newmark sliding block approach.

International Journal of Geoengineering Case Histories, 5(3) 170-181. doi: 10.4417/IJGCH-05-03-03 Analysis of a Static Loading Test on an Instrumented Cased CFA Pile in Silt and Sand Jakub G. Kania, Ph.D., cp test a/s / Aarhus University, Vejle/Aarhus, Denmark; email: [email protected] Kenny Kataoka Sørensen, Associate Professor, Department of Engineering, Aarhus University, Aarhus, Denmark; email: [email protected] Bengt H. Fellenius, Consulting Engineer, Sidney, BC, Canada, V8L 2B9; email: [email protected] ABSTRACT: A static loading test was performed on an instrumented 630 mm diameter, 12.5 m long, cased continuous flight auger (CFA) pile. The soil at the site consisted of a 4.0 m thick layer of loose sandy and silty fill layer underlain by a 1.6 m thick layer of dense silty sand and sand followed by dense sand to depth below the pile toe level. The instrumentation comprised vibrating wire strain gages at 1.0, 5.8, 9.4, and 12.0 m depth. The pile stiffness (EA) was determined by the secant and tangent methods and used in back-calculating the distributions of axial load in the pile. A t-z/q-z simulation of the test was fitted to the load-movement distributions of the pile head, gage levels, and pile toe. The load-movement response for the shaft resistance was strain-hardening. The records indicated presence of residual force.

  • Section 6D-1 Embankment Construction
    6D-1 Design Manual Chapter 6 - Geotechnical 6D - Embankment Construction Embankment Construction A. General Information Quality embankment construction is required to maintain smooth-riding pavements and to provide slope stability. Proper selection of soil, adequate moisture control, and uniform compaction are required for a quality embankment. Problems resulting from poor embankment construction have occasionally resulted in slope stability problems that encroach on private property and damage drainage structures. Also, pavement roughness can result from non-uniform support. The costs for remediation of such failures are high. Soils available for embankment construction in Iowa generally range from A-4 soils (ML, OL), which are very fine sands and silts that are subject to frost heave, to A-6 and A-7 soils (CL, OH, MH, CG), which predominate across the state. The A-6 and A-7 groups include shrink/swell clayey soils. In general, these soils rate from poor to fair in suitability as subgrade soils. Because of their abundance, economics dictate that these soils must be used on the projects even though they exhibit shrink/swell properties. Because these are marginal soils, it is critical that the embankments be placed with proper compaction and moisture content, and in some cases, stabilization (see Section 6H-1 - Foundation Improvement and Stabilization). Soils for embankment projects are identified during the exploration phase of the construction process. Borings are taken periodically along the proposed route and at potential borrow pits. The soils are tested to determine their engineering properties. Atterberg limits are determined and in-situ moisture and density are compared to standard Proctor values.

  • Soil Mechanics
    Soil Mechanics Soil is the most misunderstood term in the field. The problem arises in the reasons for which different groups or professions study soils. Soil scientists are interested in soils as a medium for plant growth. So soil scientists focus on the organic rich part of the soils horizon and refer to the sediments below the weathered zone as parent material. Classification is based on physical, chemical, and biological properties that can be observed and measured. Soils engineers think of a soil as any material that can be excavated with a shovel (no heavy equipment). Classification is based on the particle size, distribution, and the plasticity of the material. These classification criteria more relate to the behavior of soils under the application of load - the area where we will concentrate. Soil Mechanics Most geologists fall somewhere in between. Geologists are interested in soils and weathering processes as indicators of past climatic conditions and in relation to the geologic formation of useful materials ranging from clay to metallic ore deposits. Geologists usually refer to any loose material below the plant growth zone as sediment or unconsolidated material. The term unconsolidated is also confusing to engineers because consolidation specifically refers to the compression of saturated soils in soils engineering. 1 Soil Mechanics Engineering Properties of Soil The engineering approach to the study of soil focuses on the characteristics of soils as construction materials and the suitability of soils to withstand the load applied by structures of various types. Weight-Volume Relationship Earth materials are three-phase systems. In most applications, the phases include solid particles, water, and air.
