P12. Geotechnical and geological rheology
Geomaterials are widely distributed on the surface and in deep underground of the Earth and outer space in complex environmental conditions. Geomaterials are susceptible to physical and chemical processes such as mineral weathering, water-induced disintegration, strength softening, temperature influences, chemical interaction, microcrack propagation, etc. These processes give rise to pronounced rheological characteristics. This session invites contributions on the complex rheological behavior of geomaterials and their multi-scale mechanisms. Topics of interest include:
·Time-dependent nonlinear mechanical behavior of geomaterials under extreme environmental conditions (e.g., high temperature and pressure, low gravity, ultra-high vacuum, strong radiation);
·Long-term evolution of geomaterials and their behavior under conditions such as planetary weathering, supporting long-term operation of high-altitude hydropower stations, storage of nuclear wastes, etc.;
·Cutting-edge experimental techniques and devices, numerical simulation approaches, and artificial intelligence methods in georheology research.
The session aims to advance our new understandings, innovative technologies, and new methods or models in area of geotechnical and geological rheology, which will benefit humanity’s exploration and utilization of the surface and deep underground of the Earth and outer space.
