This book was released on 2011 with total page 542 pages. Available in PDF, EPUB and Kindle. Book excerpt: A verified elasto-viscoplastic finite element model is used to develop a better understanding of the performance of embankments with geosynthetic reinforcement constructed over rate-sensitive soil. The interaction between reinforcement and prefabricated vertical drains (PVDs) and their effects on time-dependent behaviour of embankments are examined. For rate-sensitive soils, the generation of creep-induced pore pressures following the end of construction is evident along the potential slip surface. As a result, the minimum factor of safety with respect to embankment stability occurs after the end of construction. The combined use of reinforcement and PVDs are shown to provide an effective means of minimizing creep-induced excess pore pressure, increasing overall stability, and decreasing deformation of the embankments. The combined effects of the viscoelastic properties of geosynthetic reinforcement (polyester, polypropylene and polyethylene) and the rate-sensitive nature of foundation soils on the performance of embankments are examined. The effect of various factors, including reinforcement type (i.e., stiffness and viscosity), soil viscosity, construction rate and allowable long-term reinforcement strain, on the time-dependent behaviour of embankments are considered. The long-term performance of reinforced embankments is investigated for different maximum allowable long-term reinforcement strains. From a series of finite element analyses, the ideal allowable reinforcement strains to minimize embankment deformation while providing optimum long-term service height of the embankment, considering the effect of soil and reinforcement viscosity, are proposed for soils similar to those examined in this study. The currently proposed design methods for embankments with creep-susceptible reinforcement over rate-sensitive soils appear to be overly conservative. This study proposes a refined approach for establishing the allowable long-term reinforcement strains that are expected to provide adequate performance while reducing the level of conservativeness of reinforced embankment design. Finally, a previously developed elasto-viscoplastic constitutive model is modified to incorporate the effect of soil structure using a state-dependent fluidity parameter and damage law. The model was evaluated against data from a well-documented case study of a reinforced test embankment constructed on a sensitive Champlain clay deposit in Saint Alban, Quebec. The benefit of basal reinforcement and the effect of reinforcement viscosity are then discussed for these types of soil deposits.

Book excerpt: Embankment construction projects on very soft soil often give rise to serious problems. This volume on geotechnics and soft soil engineering therefore treats all phases of the design and construction process exhaustively, from the first investigation step to the monitoring of constructed work. The book presents the development concepts necessary fo

Available in PDF, EPUB and Kindle. Book excerpt: A section of I-670 in Columbus, OH, constructed during 1997-1998, includes a 33 ft. (l0 m) high embankment over a deposit of very soft sludge. The design used geosynthetics for reinforcement of the embankment and wick drains to accelerate the consolidation in the sludge. Stage construction was used to allow consolidation of the sludge. To verify the design assumptions, a test embankment was completed in 1993. The performance of the test embankment provided the information for the design of the full scale embankment. This project provided the opportunity to demonstrate the application of research findings from the test embankment to actual design and construction. The objective was to demonstrate how research findings can be used in design and construction. This report shows (1) how the results of the test embankment were used in the design of the full-scale embankment and prediction of the embankment performance, (2) how observation of the embankment performance can be used as construction control and (3) how the results can be used in future application of similar technology.

The interaction of road, rail and other transport infrastructure with the ground is unusually intimate, and thus needs to be well-understood to provide economic and reliable infrastructure for society. Challenges include not only the design of new infrastructure (often on problematic ground), but inc

Book excerpt: More and more civil engineering constructions are being built on soft soils. As areas with better foundations are used up the necessity to be able to build structures on soft soils increases. The most troublesome of soft soils are organic soils due mainly to their high compressibility (much higher than in mineral soils), and also their very low shear strength. The large diversity of organic soils with respect to their origin as well as their properties make classification, testing, and engineering prediction of behaviour, very difficult. For this reason, engineers try, in general, to avoid constructing on deep layers of organic soils. If forced, by necessity, to do so, they manage with light structures e.g. embankments or low buildings. The authors of this book have been involved in a joint research project on the testing of embankments on organic soils. This was carried out in the North-Western part of Poland by the Swedish Geotechnical Institute and the Department of Geotechnics of Warsaw Agricultural University. The results of their research is presented in this new book and provides a valuable insight into this growing area in the field of engineering geology.

Available in PDF, EPUB and Kindle. Book excerpt: This thesis reports a theoretical and experimental study of the behaviour of reinforced earth embankments on soft clay foundations. Previous work on the analysis, design and modelling of reinforced earth is reviewed. Attention is drawn to limit equilibrium slip circle analysis, which is commonly used for the design of reinforced earth embankments, and the problems associated with its use are explained. -- As an alternative design method plasticity analysis provides an acceptable stress discontinuity field for this situation, and allows the calculation of a lower bound to the bearing capacity of the foundation. A rupture mechanism is postulated on the basis of the stress field and the resulting pattern of displacements is developed. -- A series of reinforced and unreinforced model tests were performed in which sand embankments, founded on layers of soft kaolin (of different thickness), were surcharge loaded to collapse. The foundation deformation fields were measured using a radiographic technique. Collapse loads and reinforcement load distributions were also recorded. These experimental tests were mathematically modelled using the CRISP finite element program, and an investigation into the effect of the reinforcement stiffness on the composite behaviour of the model was carried out. Data from a full scale instrumented embankment is also presented. -- A comparison between the theoretically predicted collapse fields of deformation in the foundation and those measured experimentally is made, and the suitability of applying plasticity theory to the design of reinforced embankments is discussed. The influence of foundation depth and reinforcement stiffness on the bearing capacity of the clay layer, and the loads measured in the reinforcement, is noted and explained in the context of the theoretical plasticity approach.
