This book was released on 2020 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the foundation is considered the major component in a structure that transfers the load to the strong strata and makes the structure stable, attention is required during the design process to select the best type of foundation. A deep foundation is considered the solution in supporting a deep, weak soil, the ground improvement is considered most economical solution in many structural developments. Among the different types of ground improvement, the stone column is an effective method to improve soft soil because it increases the bearing capacity of the soil, works as a drainage path, reduces the settlement, and is cost-effective and environmentally friendly. As an effective technique, many researchers have put forth efforts to study the behavior and optimize the performance of the stone column. However, because of deficiencies related to the column-soil system modeling, interaction modeling, full-scale field simulation, effect of column backfill material types, and loading type, further studies need to be undertaken. This research focuses on developing a numerical analysis using the finite element method to simulate Bangkok soft clay in Thailand that is reinforced with granular piles including either sand, gravel, or crushed material and that incorporates the advanced soil constitutive model and mechanical types of contact available in ABAQUS. The simulation was conducted to highlight the key aspects that would improve the performance of a foundation system of soft soil reinforced with a stone/granular column under a full response state. In addition, to verify the behavior of the column under a compression load with a focus on the surface interaction between the column and the surrounding soil and the effect of material properties on this phenomena. A design tools was developed. The simulation included column geometry (i.e. diameter and length), and soil and column properties as a parametric study to improve the performance of the foundation system.

Download or read book Influence of smear and compaction zones on the performance of stone columns in lacustrine clay written by Jean Nicolas François-Xavier Gautray and published by vdf Hochschulverlag AG. This book was released on 2019-02-20 with total page 411 pages. Available in PDF, EPUB and Kindle. Book excerpt: Construction on soft soils is always accompanied by the risk of significant, time-dependent settlement and bearing capacity failure. As technical knowledge has advanced, optimised ground improvement has offered significant economic advantages in reducing net settlement and resisting failure by installation of more flexible and cost-effective stone columns or sand compaction piles in the ground, rather than more rigid inclusions such as steel or concrete piles. The stiffness and strength of the subsoil around the columns is greater, and the consolidation time is reduced through shorter (radial) drainage paths.
Download or read book Ground Improvement by Deep Vibratory Methods written by Klaus Kirsch and published by CRC Press. This book was released on 2016-08-05 with total page 207 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vibro compaction and vibro stone columns are the two dynamic methods of soil improvement most commonly used worldwide. These methods have been developed over almost eighty years and are now of unrivalled importance as modern foundation measures. Vibro compaction works on granular soils by densification, and vibro stone columns are used to displace and reinforce fine-grained and cohesive soils by introducing inert material. This second edition includes also a chapter on vibro concrete columns constructed with almost identical depth vibrators. These small diameter concrete piles are increasingly used as ground improvement methods for moderately loaded large spread foundations, although the original soil characteristics are only marginally improved. This practical guide for professional geotechnical engineers and graduate students systematically covers the theoretical basis and design principles behind the methods, the equipment used during their execution, and state of the art procedures for quality assurance and data acquisition. All the chapters are updated in line with recent developments and improvements in the methods and equipment. Fresh case studies from around the world illustrate the wide range of possible applications. The book concludes with variations to methods, evaluates the economic and environmental benefits of the methods, and gives contractual guidance.

Download or read book Ground Improvement Techniques written by Bujang B.K. Huat and published by CRC Press. This book was released on 2019-11-06 with total page 315 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a review of problems during design and construction on problematic soils. Design methods, site investigation, construction and analysis of the various improvement methods available are explained and discussed. Various regions may have different soils with geotechnical problems that differ from those faced in other regions. For example, in Southeast Asia, the common geotechnical problems are those associated with construction on soft clays and organic soils, while in the arid region of the Middle East, problems are generally associated with the desert soils. In the US, the problems are associated with organic soils, expansive and collapsing soils, and shale. Laterite and lateritic soils are especially problematic in Mexico. Similarly, in Europe, for example, the geotechnical problems are associated with loess (France), and organic soil (Germany). A detailed description of various methods of ground improvement has been provided in 11 chapters. Each chapter deals not only with a description of the method but also focuses on region-specific ground problems and suitable ground improvement techniques. Case studies have also been included. One general chapter is dedicated to site investigation, instrumentation, assessment and control. This book will be of value to students and professionals in the fields of civil and geotechnical engineering, as well as to soil scientists and engineering geologists.

Download or read book Ground Improvement written by Professor Jian Chu and published by Elsevier. This book was released on 2005-11-07 with total page 1137 pages. Available in PDF, EPUB and Kindle. Book excerpt: - The first book of its kind, providing over thirty real-life case studies of ground improvement projects selected by the worlds top experts in ground improvement from around the globe. - Volume 3 of the highly regarded Elsevier Geo-engineering book series coordinated by the Series Editor: Professor John A Hudson FREng. - An extremely reader friendly chapter format. - Discusses wider economical and environmental issues facing scientists in the ground improvement.Ground improvement has been both a science and art, with significant developments observed through ancient history. From the use of straw as blended infill with soils for additional strength during the ancient Roman civilizations, and the use of elephants for compaction of earth dams during the early Asian civilizations, the concepts of reinforced earth with geosynthetics, use of electrokinetics and thermal modifications of soils have come a long way. The use of large and stiff stone columns and subsequent sand drains in the past has now been replaced by quicker to install and more effective prefabricated vertical drains, which have also eliminated the need for more expensive soil improvement methods.The early selection and application of the most appropriate ground improvement techniques can improve considerably not only the design and performance of foundations and earth structures, including embankments, cut slopes, roads, railways and tailings dams, but also result in their cost-effectiveness. Ground improvement works have become increasingly challenging when more and more problematic soils and marginal land have to be utilized for infrastructure development.This edited compilation contains a collection of Chapters from invited experts in various areas of ground improvement, who have illustrated the basic concepts and the applications of different ground improvement techniques using real projects that they have been involved in. The case histories from many countries ranging from Asia, America, Australia and Europe are addressed.
