水工建筑物深开挖边坡中大量出现的随机楔体 ,是由广泛分布于裂隙岩体中的结构面组成的。研究楔体的稳定性 ,首先要研究结构面的分布规律。由于裂隙的分布具有随机性与交叉复杂性 ,目前无法用确定性的研究方法进行研究 ,因此 ,应用概率与统计学的理论 ,分析组成楔体结构面的分布及组合特征 ,采用三维结构面网络模拟的方法模拟边坡工程中的结构面分布 ,进一步研究随机楔体的分布规律是研究这类问题的重要途径。基于三维裂隙网络随机模拟的方法 ,提出了随机楔体稳定分析的方法 ,可为边坡加固提供理论依据。
A large number of random wedges in the deep excavation slope of hydraulic structures are composed of structural planes widely distributed in fractured rock mass. Study wedge stability, we must first study the distribution of the structure of the surface. Because of the randomness and cross-complexity of the distribution of fractures, it is impossible to study with deterministic methods at present. Therefore, by using the theory of probability and statistics, the distribution and combination features of the structural planes of the wedge are analyzed. Simulation method to simulate the slope surface structure of the distribution, further study of the distribution of random wedge is an important way to study such problems. Based on the stochastic simulation method of 3D fracture network, a method of stochastic wedge stability analysis is proposed, which can provide theoretical basis for slope reinforcement.
