Dynamics of Freezing-Thawing Soil around Subway Shield Tunnels

The book discusses the development laws of axial strain and excess pore water pressure in silty clay around subway shield tunnels, the effect of freezing-thawing on dynamic parameters, and the microstructures of silty clay before and after freezing-thawing cyclic loading. It also presents a numerical simulation of the dynamics of silty clay around subway tunnels.

This comprehensive book delves into the intricate realm of development laws governing axial strain and excess pore water pressure in silty clay surrounding subway shield tunnels, particularly in the context of their behavior before and after freezing-thawing cycles induced by subway loading. It also explores the profound impact of freezing-thawing on the dynamic parameters of silty clay, encompassing the dynamic modulus and damping ratio. By presenting readers with a detailed introduction to the design and construction of bypasses in subway tunnels employing the artificial freezing method, the book aims to provide a solid foundation for understanding the complexities involved in this field.

To further enhance the understanding of the subject matter, the book conducts comprehensive microstructural analyses of silty clay before and after freezing-thawing cyclic loading. This is achieved through the utilization of scanning electron microscope tests and mercury intrusion porosimetry tests, which provide valuable insights into the structural changes and pore characteristics of the material under different conditions.

In order to complement the analytical findings, the book presents a numerical simulation of the dynamics of silty clay surrounding subway tunnels before and after thawing. This simulation employs advanced computational techniques to accurately model the complex behavior of the soil, enabling researchers and practitioners to gain a deeper understanding of the factors that influence its response to freezing-thawing cycles.

Given the extensive coverage of topics and the depth of analysis, this book serves as an invaluable resource for construction researchers and designers, as well as senior undergraduate and graduate students enrolled in courses related to civil engineering, geology, and soil mechanics. It provides a comprehensive understanding of the principles and practices involved in the design and construction of subway tunnels in challenging geological environments, enabling professionals to address the complex challenges posed by freezing-thawing cycles and ensure the safety and stability of underground infrastructure.
