| 摘 要： | 从工程观点出发,忽略不计完整岩块的渗透系数,借助于层面缝隙流运动规律(立方定律)和变分基本原理,建立了三维裂隙岩体渗流场和应力场耦合模型。并推出了耦合的有限元支配方程,提出了运用同一套单元网络对两场进行区域离散的观点。以重力坝坝基渗流场与应力场耦合计算为例,验证了模型的可行性。

| Abstract: | Based in neglecting the permeability in the rock block, 3D model for coupled seepage field with stress field in the fractured rock mass and its relevant governing equations are constructed by applying the cubic law and variational principle The position is proposed for using the same element nets to disperse regions in the two fields The rationality and the practical values of this model are proved by case study of calculation |

| Keywords: | Coupling Cubic law Fractured rock mass Variational principle |
