首先介绍传统的块体理论近来的发展、应用与局限.块体理论限于研究岩石开挖表面上的可移动块体.采用切割法找到所有组成岩体的任何块体,基于裂隙的平均长度与平均间距,引进产生三维裂隙多边形的统计方法.基于裂隙多边形,介绍切割三维块体的一般方法.给定一个移动方向,提出搜索关键块体的一般方法.岩体的边界可以是任何自然岩石边坡与人工开挖的任何岩体表面.该方法适用于统计产生的分组裂隙与人工输入的个体裂隙,所引进的方法属于三维非连续变形分析的切割程序DC的应用.

This paper describes a process of cutting blocks from statistically generated finite joint polygons in 3D space. If the ratio of joint length divided by joint spacing is less than 10, the rock mass is likely connected. If this joint length ratio is greater than 10, the rock is likely to be blocky. An algorithm is also presented for finding all removable blocks along any given moving direction. The rock mass boundary can be any excavated and natural free surfaces. The algorithm works for both joint sets and for any joint system where each joint has its own direction. This is an application of polygon cutting code DC of 3D DDA.
