Coupling Analysis of Stress and Seepage Fields at Xiaowan Hydropower Project Damsite
摘要
Abstract
In this paper, coupling of stress and seepage fields at the damsite area of the Xiaowan hydropower project is analyzed, and the fractal effect of rock fractured surface on the seepage flow in fractured rock masses is studied by means of numeric simulation of single fracture permeability. The fault F11 located at the right abutment is selected to study coupling effect between stress and seepage fields in fractured rock masses. The results show that the interaction of coupling fields has a dominant influence on the states of stresses and displacements in the damsite area and dam body. Also the relationship between fractal dimensions of fractured surface and seepage, stress and fractured breadth are nonlinear.关键词
