摘要

This book introduces a groundbreaking multi-field coupled constitutive model framework for unsaturated soils, rooted in the theory of thermodynamics of granular materials. By exploring the intricate energy dissipation processes at the granular level, this book offers a fresh perspective on the behavior of soils, moving beyond traditional models that rely on yield criteria and flow rules. Instead, it delves into the concepts of granular entropy and granular temperature, providing a comprehensive understanding of the dissipative mechanisms that govern soil behavior.

Key topics include the establishment of the constitutive model and the application of this innovative model to various soil types, such as saturated clays, gassy soils, and sands. The author meticulously examines the composition of the dissipative structure of thermodynamic systems and the migration coefficients, offering insights into the macroscopic physical and mechanical behaviors of soils. Through leveraging migration coefficients and energy functions to correlate the dissipation mechanisms at the soil granular scale with macroscopic mechanical behaviors, this book establishes a unified theoretical framework for soil constitutive model that enhances our understanding of soil mechanics in complex environments.

This book is a must-read for researchers, scholars, and practitioners in geotechnical engineering and soil mechanics. It provides valuable insights into the energy dissipation mechanisms and mechanical behavior of soils, offering a robust theoretical foundation for future research and practical applications.
