| 摘 要： | 本文对长江三峡工程坝址花岗岩体中缓倾角结构面成因进行了全面的综合研究。从野外地质调查人手,在大量野外勘测的基础上进行宏观分析,同时辅之以扫描电镜、透射电镜、包体温度测定等方法进行微观构造组构、差异应力等的研究。在地质力学宏观分析的基础上,利用地质力学物理模拟进行相似条件下的反演,并利用非线性有限元数值模拟进行验证。同类研究在国内外均未见先例,可为同类工程研究借鉴。

| Abstract: | The genetic mechanism of the gently dipping structural plane in granite rock mass at Three-gorges damsite is systematically studied in the paper. Based on the field investigation, SEM and TEM analyses, and determination of inclusion temperature, the microstructural fabrics and differencial stress of rock mass at the damsite were studied in detail. With the geomechnical analysis, an inversion of data for genetic mechanism of gently dipping structural plane was made after the geomechanical physical simulation under similar conditions. Then using nonlinear FEM, the result was tested by numerical simulation. Such a comprehensive study in connection with geology, mechanics, microstructure and geomechanical, physical and numerical simulations is first carried out in the world, The result of study will satisfactory for requirements of engineering construction. |
