In this volume, soil creep is analysed within the framework of other soil-rheological phenomena, such as stress relaxation and long-term resistance, to present an in-depth discussion of the effect of time on soil behaviour. As time is the only state parameter which cannot be entirely modelled in the laboratory, the presented extrapolation is based upon a combination of appropriate theoretical analysis, and the principles of the physical behaviour of soils affected by state parameters such as porosity, water content, stress, strain, time and temperature. Principal macro- and microrheological theories are analysed, and a comprehensive picture of the soil structure and of the effect of state parameters is presented, documented by the author's experiments and illustrated by many examples. The theory of hereditary creep was selected as the best theory serving the author's purpose to propose simple constitutive relations governing creep of soils. The proposed constitutive relations have been implemented into FEM programs and the effect of the time factor has been demonstrated by the solution of such boundary value problems as a dams and underground tunnels. This volume should be of interest to civil engineers, scientists, research and postgraduate students, and advanced undergraduates.

(Developments in Geotechnical Engineering, Volume 18: Stre...)
Developments in Geotechnical Engineering, Volume 18: Stress in Subsoil and Methods of Final Settlement Calculation reviews the method of settlement calculations based on stresses in the subsoil. This book is divided into three chapters. Chapter 1 deals with in situ stresses in the subsoil, while Chapter 2 focuses on the state of stress produced in the subsoil by external loads. The last chapter discusses the methods of calculating the final settlement, including remarks on the selection of deformation parameters. This publication also discusses the horizontal geostatic stress, surface loading of a half-space, method of oedometric compression, and finite element and allied methods. This volume is recommended for researchers and specialists of disciplines related to geotechnical engineering.
