摘要

水工建筑物深开挖边坡中大量出现的随机楔体

他们是由广泛分布于裂隙岩体中的结构面切割而成。首先应用随机不连续面三维网络模拟技术建立不连续的概率模型

在此基础上

搜索出临空面迹线上所有的闭合凸多变形

根据文中提出的“面积判断”法

判断块体是否为有限块体。工程实例模拟的结果说明了该方法的合理性。

Abstract

The random wedge usually occurs in the deep excavation of side slope of hydraulic structures. According to the three-dimensional network computer simulation

A numerical model of probability statistics for distribution of rockmass is established. A computational program for the method has been accomplished. With the program all polygons in trace figure are sought; and all the potential rocks can be found out of all the finite rock blocks which have free faces exposed by area-judgment method. The method is proved to be reasonable from simulated results of real engineering.
