针对水工建筑物深开挖边坡中常出现的随机楔体,应用概率与统计学理论,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稳定性及分布规律,提出了三维随机楔体的稳定性系统分析方法,为边坡加固提供了理论依据。 Based on probability and statistics theory, the statistic characteristics of joints which can be used to buill up wedges were analyzed in this paper. Furthermore, by using simulation methods, 3D joint mapping was taken out and used in the analysis of stablity of random 3D wedges.
