  • A Case History with Combined Physical and Vacuum Preloading in Colombia
    A Case History with Combined Physical and Vacuum Preloading in Colombia D.G. Yanez, F. Massad Abstract. The scope of this paper is the back analysis of soft soil treatment case studies in which prefabricated vertical drains together with physical and vacuum surcharge were applied. Initially, the vacuum surcharge systems in vertical drains used worldwide are reviewed. The radial consolidation theory specifically developed for vacuum and physical surcharges is presented, highlighting the influence of the vacuum efficiency parameter. This parameter represents whether or not there is a loss of vacuum pressure in depth. In the second moment, the local geological-geotechnical parameters of the construction are presented, from which data were used as case studies. This characterization was based on the study of regional geology, field geotechnical tests, the collection of undisturbed samples and further laboratory tests. Based on the specific consolidation theory and the geological-geotechnical characterization carried out, detailed analyzes are presented for 2 specific sites of the case study. The detailed analysis is composed of two steps of numerical modeling. The first step analyzes the vacuum loss in depth, as presented in the literature review and the second step is used to check the geotechnical parameters interpreted by the investigation campaign. At the end, comments and considerations are made about the vacuum consolidation theory and the soil characteristics in the case studies. Keywords: consolidation theories, sample quality, settlement back analysis, soft soil, vacuum surcharge. 1. Introduction 100 kPa next to sea level - a value that is lower in practice.

  • Consideration of Ground Deformation Characteristics in Vacuum Consolidation Andapplication for Design
    論文 Consideration of Ground Deformation Characteristics in Vacuum Consolidation and Application for Design ＊ ＊＊ ＊＊ ＊＊ Loan T.K.DAM ・Isamu SANDANBATA ・Kouki MATSUMOTO ・Makoto KIMURA ABSTRACT: Experience from vacuum consolidation practice revealed discrepancy between actually measured and predicted settlement and strength increment obtained by conventional designs, which can be overestimated or underestimated depending on the depth involved. It addresses the necessity of proper consideration of ground deformation under this peculiar loading. By considering the change in lateral earth pressure condition associated with inward compression of the ground under application of vacuum load, effective stress increment in the soil at any treatment depth and their distribution are established, which indicates a variation of deformation characteristics along depth. Based on that, equations have been derived for approximately estimating the vacuum induced displacement and strength increment with appropriate deformation at the corresponding depth being taken into account. On the other hand, considering the influence of vacuum consolidation beyond the treatment boundary, an approximation method is proposed to evaluate the influence zone and predict the displacement at various distances within that zone. In this paper, applicability of the proposed approach and equations are examined using data from several actual vacuum consolidation cases. As a result, some modification for the input in proposed equations are suggested for a better agreement between

ABSTRACT Based on the soil-water coupled finite element analysis incorporated the modified macro-element method, the improvement of soft ground by the vacuum and surcharge preloading method is investigated systematically. SYS Cam-clay model is employed for the constitutive model of soft soils and the soil parameters are determined by the curve fitting of the one-dimensional compression result. The results show that: 1) the settlement at the ground surface is as large as 3.5m which is very close to the design value; 2) the long-term settlement is also predicted and the degree of consolidation at 180d is over 98%; 3) Negative and positive horizontal displacement appears due to the vacuum preloading and surcharge preloading respectively and it is necessary to control the rate of surcharge to avoid the instability of the ground; 4) There is significant oscillation in the pore pressure inside the ground due to the construction of embankment and the following consolidation under vacuum pressure.

Professor, 2Asst. Professor, Aryabhatta college of Engineering & Aryabhatta College of Engineering & Research Centre, Research Centre, Ajmer, Rajasthan, India Ajmer, Rajasthan, India ABSRACT In the early times before the advancement in the geotechnical engineering, the only chance for the foundation engineers was to design the foundation matching to the sub soil conditions at the provided site. But now a day due to the improvements in geotechnical techniques and with the help of latest technology it is possible for us to modify the weak foundation soil to the strength and compressibility characteristics to suit the foundation of our choice. Thus these geotechnical processes of improving the quality of the foundation soil to our desired quality are called as ground improving techniques. The changes made through the process are permanent and are not effected with the passage of time or due to change in the weathering condition. The main objective of these processes is to increase the density and shear strength parameters and to decrease the compressibility, permeability and the settlement, which makes the soil more water resistant, durable and stable. This paper gives the overview and concept of recent major ground improvement techniques and discusses their practical applications.

The discrete system of vertical drains is substituted by continuous concentric rings of equivalent drain walls. The effectiveness of the vacuum as distributed along the drain length and the well resistance of the drains are considered. A rigorous solution of radial drainage towards cylindrical drain walls is presented and compared to numerical FEM predictions. The model is then successfully adopted to analyse the vacuum consolidation of a circular embankment in the Ballina field testing facility in Australia.

  • Influence of Vertical Drains on Improving Dredged Mud by Vacuum Consolidation Method
    Journal of Science and Technology in Civil Engineering NUCE 2018. 12 (5): 63–72 INFLUENCE OF VERTICAL DRAINS ON IMPROVING DREDGED MUD BY VACUUM CONSOLIDATION METHOD Phan Huy Donga,∗ aFalcuty of Bridge and Highway Engineering, National University of Civil Engineering, 55 Giai Phong road, Hai Ba Trung district, Hanoi, Vietnam Article history: Received 30 July 2018, Revised 27 August 2018, Accepted 30 August 2018 Abstract Vacuum consolidation preloading method (VCM) has been widely adopted as an effective solution for soft soil improvement over the world. Recently, VCM has been successfully applied for improving the geotechnical properties of dredged mud, which is normally dumped at reclamation area by hydraulic pumping. However, it has been also reported that application of VCM for treatment of the dredged mud has been failed in some particular cases. The failures are mainly caused by clogging problem in vertical drains due to fine-grained soils that reduces the drainage efficiency of drainage system. To address this issue, a series of model tests have been conducted to investigate the performances of vertical drains among prefabricated vertical drain, sand drain and filter pipe. As the goal, the performances of types of the vertical drain solutions are analyzed based on the monitoring data of settlement, influencing zone surrounding the vertical drains. The test results reveal that sand drain shows the best performance among the others. In addition, the clogging problem is clearly shown in case of PVD.

  • Construction Methods in Brazilian Extremely Soft Soils
    Construction methods in Brazilian extremely soft soils Almeida, M. S. S. COPPE - Federal University of Rio de Janeiro, Rio de Janeiro, Brazil Marques, M. E. S. Military Institute of Engineering, Rio de Janeiro, Rio de Janeiro, Brazil ABSTRACT About half of the population in Brazil lives in a 100 km strip along the coast, where ports and industries are also concentrated. The soil deposits found in coastal city areas in Brazil may consist of lowlands with a high water table, low strength and high compressibility. With increasing development, lowlands areas are increasingly occupied, where soft clay deposits may reach a thickness up to 40 m. This paper presents the Brazilian experience in the last couple of decades in issues related to geotechnical investigation, design and construction in lowlands. Emphasis is given to cases involving very soft and compressible ground found in south-east areas of Brazil, particularly on the west side of the city of Rio de Janeiro, where the authors’ experience has been concentrated in recent years. The geotechnical characteristics of these uncommon very soft soils are outlined, followed by a description of the main methods adopted for the construction of embankments on these very soft clays. Discussion of new construction techniques on these soils is also presented. RÉSUMÉ Environ la moitié de la population vit au Brésil dans une bande d’environ 100 km le long de la côte, où les ports et les industries sont également concentrées. Les dépôts de sols dans les zones des villes côtières au Brésil peut être constitués de marnes avec une nappe phréatique élevée, faible résistance et de la compressibilité élevée.

  • Ground Modification
    Caltrans Geotechnical Manual 1.0 Ground Modification Ground modification technologies are geotechnical construction methodsused to improve poor ground conditions whenremoval and replacement, avoidance of such conditions, or the use of deep foundations is infeasible or too costly. Ground modification may be used to: • Mitigate liquefiable soils. • Improve loose or soft soil to reduce settlement, increase bearing capacity, shear, or frictional strength as well as overall improvement of stability for embankment and structure foundation. • Improve slope stability for mitigation of landslides. • Increase density. • Decrease imposed load. • Form seepage cutoff or fill voids. • Accelerate consolidation. • Control deformation. • Provide/increase lateral stability. • Reduce earth pressures. There are three strategies available to accomplish the above functions: 1. Increase shear strength, density, and/or decrease compressibility of foundation soil, 2. Reduce the applied load on the foundation soil by the use of lightweight fills, 3. Transfer the load to a more competent (deeper) foundation soil. Ground Modification Methods, Volumes I and II, FHWA NHI-16-027 and FHWA NHI-16- 028, April2017 are frequently referenced in this module. The Geoprofessional should consult each volume for details concerning a specific ground modification method. Also be aware of new and innovativeground modification methods. If a new or innovative ground modification method is to be considered on a Caltrans project, the method should be discussed with the Project Development Team including Construction. Sometimes it will become necessary to initiate constructiona evaluation project to measure the effectiveness of a new or innovative ground modification technique prior to its use. A web-based information and guidance system,Geotechnical Solutions for Transportation Infrastructure (Geotech Tools ), presents information on geoconstruction technologies and provides a tool to assist in deciding which technologies are potentially applicable to site-specific conditions.

  • Vacuum Consolidation Method – Worldwide Practice and the Latest Improvement in Japan
    報 告 Vacuum Consolidation Method – Worldwide Practice and the Latest Improvement in Japan Loan T.K.DAM ＊ ・Isamu SANDANBATA＊＊・Makoto KIMURA＊＊ ABSTRACT: Vacuum consolidation method is a technique of applying vacuum suction to an isolated soil mass to reduce the atmospheric pressure in it, thus by the way of reducing the pore water pressure in the soil the effective stress is increased without changing the total stress. By improving construction techniques, as well as developing analytical methods for designing, the technique has become an effective and economical method for soft ground improvement and capable to conduct in various site conditions. Researches are also extended to other application fields such as acceleration dewatering and consolidation of fluid-like materials. Conducting of numerous vacuum consolidation projects has been tried in many countries in the world, through that practical experiences are accumulated, which would have significant importance in improving its efficacy and advancing the technique. For the purpose of gaining experience, numbers of published documents and research papers on vacuum consolidation practice from leading countries in this field of technology have been reviewed. This paper summarizes and compares various vacuum consolidation systems with emphasizing on system specification and configuration, design and construction practice, and introduces the newest improvement of this technology in Japan.
