This book presents a systematic framework for evaluating slope stability under short-term heavy rainfall by integrating numerical simulation with GIS-based analysis. It covers several key aspects, including the simulation of heterogeneous weathered soils in FLAC3D and experimental approaches for determining the hydraulic properties of unsaturated soils. In addition, it addresses unsaturated seepage and slope stability analysis under rainfall conditions using FLAC3D, as well as GIS-based as...

Seismic damage to rock tunnels from recent earthquakes indicates an urgent need for seismic assessment and aseismic design of underground structures. This book offers a comprehensive account of seismic performance and the response of underground structures under earthquake loading, necessary for adequate assessment and design.The book presents research methods for the rate-dependent mechanical behavior of rock and for the seismic behavior of underground structures. It describes ana...

Through a meticulous analysis of various historical sources, the authors of this book have uncovered a wealth of information on the trade of salt and tobacco in Guizhou province, southwest of China, in the 1930s and 1940s. Their findings not only shed light on how commercial networks and the flow of these commodities formed and transformed with the development of wartime state monopoly, but also offer a more comprehensive perspective on the role of merchants and entrepreneurs in regulated ...

This open access book presents the Coal remains the primary energy source in China, with an estimated total coal reserve of 59 trillion tons at depths of less than 2000 meters. Among these, over 50% lie at depths exceeding 1000 meters, primarily distributed in central and eastern China. Deep coal mining has become the new norm for the coal industry’s development and resource exploitation. To ensure energy supply for the rapid economic development of central and eastern regions, mining coal...
