About this Research Topic
Global climate change, the rapid expansion of human activities, and the continuous increase of engineering operations lead to a strong impact on the geological environment. A wide variety of geotechnical and geological disasters have occurred worldwide, including geotechnical disasters such as slope instability, tunnel damage, and deep excavation collapse, as well as natural geological disasters，such as rock collapse, landslide, and debris flow. These hazards seriously affect economic development and human safety. Research on the modeling, assessment, and prevention techniques of geotechnical and geological disasters is a key solution in disaster control.
Considering the characteristics of geotechnical and geological disasters, many new numerical methods, such as DEM (Discrete Element Method), DDA (Discontinuous Deformation Analysis), NMM (Numerical Manifold Method), SPH (Smoothed Particle Hydrodynamics), MPM (Material Point Method) and PD (Peri Dynamics), have emerged after the classical FEM (Finite Element Method) and FVM (Finite Volume Method) modeling techniques. Different assessment methods for the single geotechnical project, linear geotechnical engineering, and territorial natural disasters have been proposed. In addition to active and passive engineering reinforcement measures, advanced monitoring technologies including InSAR (Interferometric Synthetic Aperture Radar), Beidou, UAV (Unmanned Aerial Vehicle), Fiber Optics, and MEMS (Micro-Electro-Mechanical System) have been utilized in terms of prevention techniques. Rich progress has been made by researchers in the field of modeling, assessment, and prevention techniques.
This Research Topic aims to provide an outlet for peer-reviewed publications that implement state-of-the-art methods and techniques to model, assess and prevent geotechnical and geological disasters. The topics include, without being limited to, the following areas:
1. Mechanical properties and constitutive models of special geological materials，such as jointed rock mass, SRM (soil-rock-mixture), and special soil
2. Applications of numerical simulation methods in geotechnical and geological disasters
3. Mechanism of geotechnical and geological disasters subjected to the environmental factors (earthquake and rainfall, etc.) and engineering load factors (excavation, blasting, reservoir, etc.)
4. Applications and developments of advanced assessment and prevention techniques in geotechnical disasters (slope instability, tunnel damage, deep excavation collapse, etc.)
5. Applications and developments of advanced assessment and prevention techniques in geological disasters (rock collapse, landslides, debris flow, etc.)
