引言 岩石块体的稳定分析在岩体工程地质力学研究中已经逐渐形成一个重要的课题,很多文献在这方面进行了探讨。 在岩石块体的稳定分析时,由于多组结构面的约束,往往遇到超静定问题而不好解决。即使是四面体这样一种岩体中最基本的结构体,它的稳定分析也很不完善。迄今为止,大部分文献都把块体的初始受力当作共点力系来研究。这种力系的自由运动趋势只能是平 INTRODUCTION Stable analysis of rock mass has gradually formed an important issue in the study of rock mass engineering geomechanics. Many documents have been discussed in this respect. In the rock block stability analysis, due to the constraints of multiple sets of structural surfaces, often encounter the problem of statics and not good solution. Even the most basic structure, such as a tetrahedron, is poorly characterized. To date, most of the literature has studied the initial force of a block as a total force system. This force of the free movement trend can only be flat
