摘要
本文综合讨论了裂隙岩体渗流参数的特征,及由裂隙参数确定岩体渗透张量的过程。叙述了将岩体作为连续介质的三维非均质各向异性稳定渗流场有限元计算方法。通过对简单模型的有限元计算分析,讨论了各向异性渗流场的二个特征,即渗透主轴对渗流场的控制意义、以及渗透主轴与边界的关系对渗流场的控制意义。
This paper comprehensively discusses the characteristics of fractured rock permeability and the processes of determining rockmass permeability tensors by fracture parameters. Finite element compu tation method is used to simulate the 3-D anisotropic steady seepage field of rocd mass as continuous media. By means of finite element simulation and analyses of a simple model, we discussed the two characteristics of anisotropic seepage field, i. e. effect of principal axes on seepage field, and of principal axes versus boundary on the same.
