Available in PDF, EPUB and Kindle. Book excerpt: The mechanism of soil-reinforcement interaction for a reinforced embankment on soft clay has been explored by conducting a parametric study using a coupled non-linear elastoplastic finite element program. One of the major issues in the design of a reinforced embankment on soft clay is the magnitude of tension that can be mobilized in the geosynthetic reinforcement. Previous research using geotechnical centrifuge modelling and present research using finite element modelling has confirmed that the tension mobilized in the reinforcement is only of the order of active lateral thrust in the embankment. The parametric study has revealed that the soil-reinforcement interaction mechanism depends on the ratio of embankment height to the depth of the clay layer. The embankment behaves similar to a rigid footing in case of deep clay deposit. In this case, the failure mechanism is similar to a slip circle and there is very little contribution from the clay-reinforcement interface towards the mobilization of reinforcement tension. However, if the depth of clay deposit is small, the soil-reinforcement interaction mode is similar to direct shear failure and slip surface is located close to the clay-reinforcement interface. In this case, the contribution of clay-reinforcement interface towards the tension mobilized in the reinforcement is higher and therefore, the contribution of the reinforcement towards overall stability of the embankment is greater. Based on the results of the parametric study a novel serviceability criterion is proposed that aims to limit the lateral deformation of the clay foundation at the toe of the embankment by limiting the allowable mobilized tension in the reinforcement. A simple procedure for the evaluation of the efficiency of soil-reinforcement interface for reinforced embankments on soft clays is also proposed. The validity of the proposed serviceability criterion and the design charts was successfully tested using two field case studies. Sackville t.

This book was released on 2013-09-03 with total page 230 pages. Available in PDF, EPUB and Kindle. 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 for the project stages and discusses in great detail construction methods, displacement estimations, stability analyses, monitoring, and various other aspects involved. Extensive attention is furthermore paid to the application of geosynthetics as a tool to improve the stability of soft soils and embankments. Including various tables and practical data for many geographical areas in the world, this reference volume is essential reading for engineers and researchers in geotechnical engineering, construction, and related disciplines.

Book Synopsis Handbook of Geotechnical Investigation and Design Tables by : Burt G. Look
Download or read book Handbook of Geotechnical Investigation and Design Tables written by Burt G. Look and published by CRC Press. This book was released on 2014-02-10 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: This practical handbook of properties for soils and rock contains in a concise tabular format the key issues relevant to geotechnical investigations, assessments and designs in common practice. There are brief notes on the application of the tables. These data tables are compiled for experienced geotechnical professionals who require a reference document to access key information. There is an extensive database of correlations for different applications. The book should provide a useful bridge between soil and rock mechanics theory and its application to practical engineering solutions. The initial chapters deal with the planning of the geotechnical investigation and the classification of the soil and rock properties, after which some of the more used testing is covered. Later chapters show the reliability and correlations that are used to convert that data in the interpretative and assessment phase of the project. The final chapters apply some of these concepts to geotechnical design. The emphasis throughout is on application to practice. This book is intended primarily for practicing geotechnical engineers working in investigation, assessment and design, but should provide a useful supplement for postgraduate courses. It evolved from the need to have a "go to" reference book which has both breadth and depth of information to apply immediately to projects. To keep to a handbook size one has to compress/restrict details to a few key bullet points – but a comprehensive reference list provides the "appendix" for additional information if required. This 2nd edition keeps to that format but contains updated information and adjustments that take into account feedback received since initial publication.

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.
