摘要：

Based on the analysis of discontinuity and anisotropy of columnar joints, a 3D numerical simulation is carried out for an arch dam and its foundation. Considering the initial ground stress of river valley and anisotropic mechanical property of rock mass, the computation results with isotropic and anisotropic models are compared and analyzed. The result shows that the characteristics of columnar joints have obvious influence on the stress and displacement of engineering rock mass. The influence of columnar joints on dam or abutment stability is very important; and a successful application is provided for the analysis of anisotropic property of rock mass in this dam area.
