| 摘 要： | 针对水工建筑物裂隙岩基渗流场计算，采用双重介质解法编制了三维有限元裂隙渗流计算程序，用水量交换项耦合主干裂隙网络及裂隙岩块，自由面位置的确定使用自由面虚点法迭代逼近，得到了合理的计算结果。计算使用ANSYS建立渗流模型并剖分网格，相应的前处理子程序降低了裂隙渗流计算的复杂性，提高了裂隙渗流理论计算方法的可用性。

| Abstract: | The article is aimed at the computation of seepage field in fractured rocks of hydraulic projects, presents a 3-D finite element analyzing program according to the method of Double-medium Solution, in which the main fracture network and the fracture rocks are coupled by interchanged water. In the program, the position of the free face is found by imaginary point method and reasonable results are obained. The seepage model for computation is set up and divided grids directly by the software of ANSYS, the corresponding pre-disposal program greatly simplifies the computation and increases the practicability of the theoretic methods. |
