Advanced geotechnical engineering. Soil–structure interaction using computer and material models / Передовые геотехнические разработки. Взаимодействие грунта и структуры с использованием компьютерных моделей и моделей материалов

Soil–structure interaction is a topic of significant importance in the solution of problems in geotechnical engineering. Conventional and ad hoc techniques are usually not sufficient to understand the mechanism and model the challenging behavior at the interfaces and joints prevalent in most structural and foundation systems. In addition to mechanical loading, the behavior of structures containing interfaces can be affected by environmental factors such as fluids, temperature, and chemicals.

Understanding and defining the behavior of engineering materials and interfaces or joints are vital for realistic and economic analysis and design of engineering problems. Hence, constitutive modeling that defines the behavior of the materials and interfaces, related testing, and validation assume high importance. Owing to the complexities involved in many geotechnical problems, conventional procedures based on assumption of the linear elastic and isotropic nature of materials, and limit equilibrium procedures are found to be insufficient. Hence, we need to use modern computer-oriented procedures to account for factors, such as in situ stress, stress path, volume change, discontinuities and microcracking (initial and  induced), strain softening, and liquefaction, which are not accounted for in most conventional methods. Hence, the objective of this book is to present various computerbased methods such as finite element, finite difference, and analytical.
The details of these methods are presented for the solution of one-, two-, and threedimensional problems. Various constitutive models for geologic media (“solid”) and interfaces, from simple to advanced, are included to characterize appropriately the behavior of a wide range of materials and interfaces <...>
