This project belongs to the discipline of engineering geology. Geotechnical disasters triggered by strong earthquakes are one of the main disasters of earthquakes. They have high occurrence rate, large impact range, strong suddenness and disaster-causing capabilities, and complex dynamic disaster processes. At present, there are insufficient research on the evolution laws of geotechnical disasters triggered by strong earthquakes, and there are also deficiencies in the calculation models and simulation evaluation methods to reproduce this complex disaster-causing process. Based on the country's major needs for disaster prevention and reduction, and relying on scientific research projects such as the National Natural Science Foundation of China, the project team focused on& ldquo; evolution laws and simulation evaluation of geotechnical disasters triggered by strong earthquakes& rdquo; On this key scientific issue, through the comprehensive research method of on-site investigation, experimental research, theoretical analysis and numerical simulation, important scientific discoveries have been made: in terms of evolution laws: the anisotropic change characteristics of ground motion action have been clarified, and the ground motion has been comprehensively considered. The spatial differential effect and near-far field effect reveal the site seismic effect under the influence of the directivity of ground motion; The microstructure change characteristics of rock and soil mass under strong earthquakes were discovered, and the nonlinear failure laws of rock and soil mass were revealed, and the spatio-temporal deduction of the geological disaster failure process based on the anisotropy of earthquake loads was realized; The evolution law of the coupling between rock and soil mass and engineering structures was successfully clarified under strong earthquakes, and the high-precision integrated test system was used to effectively reveal the control law of the anisotropic failure characteristics of rock and soil mass on the damage effect of engineering structures. In terms of simulation evaluation: the formation mechanism of anisotropic failure of rock and soil induced by earthquake forces is proposed, and a multi-yield surface rotation-hardening constitutive model suitable for the generalized stress space is established to accurately describe the anisotropic failure characteristics of rock and soil under strong earthquakes; A unified full-system model to simulate the evolution process of disasters has been constructed, accurately reproducing& ldquo; strong earthquake-environment-human activities&; The coupled evolution process provides strong data support for subsequent disaster risk analysis and evaluation; With the help of a spatial sensing network and integrating advanced machine learning algorithms, a multi-scale simulation and evaluation system for geotechnical disasters triggered by strong earthquakes has been built. The evaluation system has been successfully applied to achieve accurate positioning of high-risk disaster areas and effective real-time monitoring of extremely high-risk disaster points., providing basic theoretical support for the layout of engineering structures and land spatial planning and remediation decisions in dynamic environments in areas affected by strong earthquakes.
