Book Description
Reasonable estimates indicate that approximately a billion cubic meters of high water content soil-like wastes are produced annually worldwide, and a large portion of these are deposited hydraulically in diked impoundment areas, some of which are among the largest earth structures in the world. The major problems emanating from this disposal method are the difficulty in dewatering the wastes, their low strength and hydraulic conductivity, their high compressibility, their potential to contaminate the groundwater, the stability of the confining dikes, and the ultimate reclamation of the disturbed land. Following a brief explanation of how many of these wastes are generated, quantitative values for key engineering properties are summarized and compared for a wide variety of waste materials and some reference soils. Then, many concepts that have been applied with success will be presented together with the advantages each offers, the difficulties involved in using it, and the limitations in our knowledge. Discussed briefly will be state-of-practice developments in mathematical modeling, laboratory testing and associated interpretations, and material property formulations.

Book Description
Two intrusive in-situ measurement systems, the C-CORE Shear Wave Profiling System and the Oxford University Densimeter, were used to carry out in-situ profiles of bulk density and shear wave velocity in contaminated dredge spoils. The spoils have high water content and, at the time of the survey, exhibited densities in the range of 1160 kg/m 3 to 1302 kg/m 3 and undrained shear strengths in the range of zero to 2.7 kPa, in the uppermost 3.85 metres of the deposit. The objective of using the above technologies was to provide a profile of in-situ small strain shear stiffness of the deposit through the combination of the bulk density and shear wave velocity measurements.

Book Description
Peat and organic soils commonly occur as extremely soft, wet, unconsolidated surficial deposits that are an integral part of wetland systems. These types of soils can give rise to geotechnical problems in the area of sampling, settlement, stability, in situ testing, stabilisation and construction. There is therefore a tendency to either avoid building on these soils, or, when this is not possible, to simply remove or replace soils, which in some instances can lead to possibly uneconomical design and construction alternatives. However, in many countries of the world, these soils cover a substantial land area and pressure on land use is resulting in ever more frequent utilisation of such marginal grounds. For the successful design, construction and performance of structures on such marginal soils, it is crucial to predict geotechnical behaviour in terms of settlement, shear strength and stability, with respect to time. This means expanding our knowledge base and calls for a reliable characterisation of their geotechnical properties and mechanical behaviour and subsequently, the devising of suitable design parameters and construction techniques for dealing with these materials. A sound scientific understanding of the nature and functions of peat and organic soils is critical to their correct and safe use, and this book contributes by offering students, researchers, engineers and academics involved with these types of soils a comprehensive overview. This book will be useful not only to those in the field of geotechnical engineering, but also to soil scientists and agriculturalists, who are involved in the development of peatlands.

Book Description
This book presents a one-stop reference to the empirical correlations used extensively in geotechnical engineering. Empirical correlations play a key role in geotechnical engineering designs and analysis. Laboratory and in situ testing of soils can add significant cost to a civil engineering project. By using appropriate empirical correlations, it is possible to derive many design parameters, thus limiting our reliance on these soil tests. The authors have decades of experience in geotechnical engineering, as professional engineers or researchers. The objective of this book is to present a critical evaluation of a wide range of empirical correlations reported in the literature, along with typical values of soil parameters, in the light of their experience and knowledge. This book will be a one-stop-shop for the practising professionals, geotechnical researchers and academics looking for specific correlations for estimating certain geotechnical parameters. The empirical correlations in the forms of equations and charts and typical values are collated from extensive literature review, and from the authors' database.

Book Description
As the pressure to conserve agricultural land and green-field sites has grown it has become increasingly important to reclaim land that has been damaged by past industrial usage, e.g. areas of mining subsidence, tailings dams and lagoons. Furthermore the need to conserve primary aggregates is providing an impetus for re-use of waste materials in engineered construction.This book is the proceedings of the GREEN3, the third in a four-yearly series of international symposia that discuss aspects of geotechnical engineering intimately related to the environment.

Book Description
This book is the second volume of the proceedings of the 4th GeoShanghai International Conference that was held on May 27 - 30, 2018. This conference showcased the recent advances and technology in geotechnical engineering, geoenvironmental engineering and transportation engineering. This volume, entitled “Multi-physics Processes in Soil Mechanics and Advances in Geotechnical Testing”, covers a wide range of topics in soil mechanics, focusing on the behaviours of partially saturated soils, combined effects of multi-physics processes in geological materials and systems, and emerging methods and techniques in geotechnical in-situ testing and monitoring. This book may benefit researchers and scientists from the academic fields of soil and rock mechanics, geotechnical engineering, geoenvironmental engineering, transportation engineering, geology, mining and energy, as well as practical engineers from the industry. Each of the papers included in this book received at least two positive peer reviews. The editors would like to express their sincerest appreciation to all of the anonymous reviewers all over the world, for their diligent work.
