| 摘 要： | 本文研究了小湾电站坝址区岩体渗流场与应力场的耦合相互作用，并结合右坝肩Ｆ１１断层的特性，探讨了裂隙内具有不同填充物情况下，裂隙表面分形对裂隙渗流和应力的影响，通过数值分析，得到了场耦合情况下的渗流分布及断层Ｆ１１在不同应力水平下的分维数－渗流量、不同分维数下的应力－裂隙开度、应力－流量关系曲线。

| 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 F 11 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. |
