摘要
本文首先讨论了岩体渗透率张量法存在的缺陷,提出了修正渗透率张量法并编制了相应的计算程序。其次,用渗透率张量法计算了长江三峡三斗坪坝址花岗岩体的渗透率。最后,分析了渗透率张量法、实际岩体中导水裂隙量测法、节理导水网络计算机模拟法的结果,得出了较一致的结论,这三种方法的结果较真实地反映了岩体的渗透习性。
This paper first discusses the deficiency of the tensor method in permeability rate assessment of rock mass. It presents the revised tensor method and compiles the computer programme. Then, it calculates the permeability rate of granite rock mass in Sanxia Sandouping dam site of Yangtze River using the tensor method, Finally, it analyzes the results of the three methods: tensor method, water conductivity fissure measurement in actual rock mass and water conducting joint network computer simulation. It concludes that the results are concordant. The results of these methods genuinely reflects the permeability characteristics of the rock mass.
