摘要： 根据对岩体结构面及地下水渗流量的调查和观测,概化出渗透结构面及其分组,利用极值控制法求出渗透结构面的渗透系数,进而求出岩体初始渗透张量;基于初始渗透张量及观测渗流量利用有限元法反求岩体等效渗透张量.该方法能够比较客观地确定施工过程中岩体的等效渗透张量.

Abstract: According to analysis and observations in-situ the authors conclude one solution(i.e.scientific solution of equivalent seepage tensor of rock mass, abbr.SSEST) that is useful in identifying equivalent seepage tensor of rock mass in the construction of Geotechnical project.The solution is effective in fissured rock mass.The solution includes two steps, and the first step is fixed on initial permeability using WCF(water-conduction fracture), and the second is calculating SSEST using the initial permeability.The solution is used successfully in seepage researches in slope of permanent shiplocks of the Three Gorges Project.

Key words: rock mass, water-conduction fracture, seepage discharge, seepage tensor, the Three Gorges Project
