Methods of Treatment of Unstable Ground focuses on the methods of treatment that have been adopted by engineers in their attempts to make unstable ground usable. These methods are meant to stabilize ground, either temporarily as in ground-water lowering or freezing techniques, or permanently as in grouting. This book is comprised of 11 chapters. The first of which reviews some of the modern techniques in addressing problems caused by unstable ground, including those caused by water in excavations, instability of natural or excavated slopes, the settlement of structures on soft or loose soils, and subsidence due to extraction of minerals from the ground. These techniques range from ground-water lowering to the use of an impermeable barrier around the excavation to prevent inflow and at the same time maintain the surrounding water table at its normal level. Attention then turns to the use of electro-osmosis and electrochemical stabilization in ground engineering; control of groundwater by excluding it through grouting; and fundamental conditions governing the penetration of grouts. The remaining chapters explore grout selection based on engineering performance; ground conditions in mining areas; clay grouting and alluvial grouting; and ground freezing. Finally, the use of cement to stabilize soil and of vibroflotation to improve poor ground below foundations of structures is described. This book should prove useful to engineers engaged in ground engineering.

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.

Written by an author with more than 25 years of field and academic experience, Soil Improvement and Ground Modification Methods explains ground improvement technologies for converting marginal soil into soil that will support all types of structures. Soil improvement is the alteration of any property of a soil to improve its engineering performance. Some sort of soil improvement must happen on every construction site. This combined with rapid urbanization and the industrial growth presents a huge dilemma to providing a solid structure at a competitive price. The perfect guide for new or practicing engineers, this reference covers projects involving soil stabilization and soil admixtures, including utilization of industrial waste and by-products, commercially available soil admixtures, conventional soil improvement techniques, and state-of-the-art testing methods. Conventional soil improvement techniques and state-of-the-art testing methods Methods for mitigating or removing the risk of liquefaction in the event of major vibrations Structural elements for stabilization of new or existing construction industrial waste/by-products, commercially available soil Innovative techniques for drainage, filtration, dewatering, stabilization of waste, and contaminant control and removal

Systematic treatment of difficult ground as a separate paper in undergraduate and postgraduate courses is gaining ground in Indian universities. Earlier, these topics were taught under a variety of subjects like Advanced Geotechnical Engineering, Retaining Structures, Dams, Pavement Designs, Application of Geosynthetics, Application of Soil Mechanics, and so on. However, field requirement and advances in the technology make a strong case for a focused treatment of the subject which this book provides. A full-fledged paper in ground improvement techniques concentrates on the topics of soil stabilization, compaction, preloading, vertical drains, geosynthetics, in-situ reinforcements and modelling of soil reinforcement. The book provides an overview of the basic concepts of ground modifications to difficult soils in a logical and illustrative way. It teaches how to apply alternative solutions to difficult foundation problems and evaluate their effectiveness before and after construction. The text is supported by a large number of examples, review and multiple choice questions, as well as practical problems. The book is intended to serve as a textbook for undergraduate and postgraduate students of Geotechnical, Transportation, Hydraulic and Environmental Engineering, and a reference work for practising civil engineers. Salient features 1. A well researched textbook on ground improvement techniques 2. Conforms to the syllabi of all Indian universities where the subject is taught 3. Written by an expert on the subject with a decade of teaching experience

Due to the unavailability of good construction sites owing to the growth of cities and industries, the site engineers are nowadays compelled to adopt methods of forcing the weak soil to behave according to the project requirement. Written in the same context, the book focuses on the fundamental principles and practical methods of ground improvement. The design and constructional procedure of different ground improvement methods are comprehensively covered in the text. The subject-matter, divided into fourteen chapters, is organised into a simplified and logical manner to describe first the working methods and then the possible future developments. The book enables its readers to become aware of the overall methodology to be adopted in a particular case and seek possible solution to the chosen field. It is primarily intended to cater the needs of undergraduate and postgraduate students of civil engineering and geotechnical engineering. KEY FEATURES • Numerous figures, tables and mathematical equations are provided to support the topics discussed. • Several worked-out examples are provided in most of the chapters. • Objective questions, descriptive questions and references are given at the end of each chapter. • Numerical questions are given for practice in the relevant chapters. • An appendix introduces miscellaneous topics related to soil.
