摘要
分析结构面在岩体中的分布和组合特征是研究岩体稳定性的前提。根据结构面网络随机模拟方法,通过对岩体表面结构面的测量,可以建立岩体结构面空间分布的概率统计模型,从而确立了岩体结构面的网络结构模型。在此基础上分析了局部临空块体的空间几何形态,指出了块体的可能破坏形式,从宏观角度对块体系统整体稳定性进行了预测。
Analyses of the distribution of rockmass discontinuities and their association characteristics are prerequisites for studying stability of rock mass. According to the discontinuity network stochastic simulation method, based on the surveying data of the discontinuities which are on the rock mass＇s surface, a numerical model of probability statistics for distribution of discontinuities of rock mass can be established; and a network structural model of discontinuities of rock mass is determined. With the model, 3D geometrical forms of free blocks are analyzed; and the possible destruction forms of the blocks are to be pointed out. Meanwhile, the integral stability of block system is to be forecast in macroscopic perspective.
