摘要
根据结构面发育的主要特点以及工程实际需要,合理选择划分岩体结构均质区的岩体参数是必要的。在某些特殊情况下,选择结构面密度作为划分均质区的依据更为合适。为此,提出了一种基于结构面密度的岩体结构均质区划分方法,即密度分区方法,并通过对西南某大型水电站工程侧裂结构面的密度分区,证明了该方法的可行性。该方法简单、直观、易于操作,有很强的推广实用价值。
It is a kind of conventional method to analyse the structural homogeneity of rock mass according to statistical data of discontinuity orientation. However, if the discontinuity orientation is similar in an area, this method should not be used to evaluate homogeneity of structural populations. So a new method is put forward to analyse the structural homogeneity of rock mass based on discontinuity density, and it is successfully applied to analysis on the structural homogeneity of discontinuities for sideslip surface in a large hydropower project in Southwest China.
