| 摘 要： | 总结了近年来裂隙岩体渗透系数的确定方法,主要有现场水力试验法、裂隙测量法和离散裂隙网络渗流数值试验法。每种方法都有自己的适用性和测量尺度。裂隙岩体渗透系数存在尺度效应,针对不同尺度的研究对象,应尽量选取与渗流模型网格剖分尺度匹配的测量方法。裂隙的延伸具有方向性,测试点的布设应合理科学,不同测量方法需要结合起来才能得到裂隙岩体真实的渗透系数。

| Abstract: | Determination methods of hydraulic conductivity of fractured rocks in recent years were summarized in this paper.Field hydraulic tests,fracture measuring,numerical flow test method of discrete fracture network are often used to determine hydraulic conductivity.Each kind of investigation methods has its applicability and test scale.As the scale effect of hydraulic conductivity is significant in fractured rocks,the investigation method which has the measuring scale consistent with the model grid scale should be chosen to determine hydraulic conductivity.Distribution of investigation points needs to be considered in the orientation of fractures and different kinds of investigation methods may be used jointly to determine hydraulic conductivity. |
