It has important scientific value and practical applications in regional tectonic evolution and earthquake disaster research. This paper intends to study the deformation laws and deformation mechanisms of the deformed rock mass from two aspects: deformation rupture characteristics and stability mechanism. The research will mainly focus on the following aspects: ① determination of the physical and mechanical parameters of the rock mass; ② field geological investigation and core drilling sampling, combined with optical microscopy, scanning electron microscopy and other means to analyze the petrology and microstructure characteristics of the rock mass; ③ describe and analyze the deformation rupture characteristics of the rock mass, and explore its deformation mechanism from the mechanical level; ④ verify the deformation laws and stability mechanism of the rock mass through numerical simulation and model experiments. The research results will provide reference and support for regional tectonic evolution and earthquake disaster prediction.精品文档---下载后可任意编辑Keywords: Yalongjiang Kaqiang; deformed rock mass; deformation rupture characteristics; stability mechanism; numerical simulation.
