摘要
块体理论是近十几年来发展起来的一种岩体工程稳定分析方法,它适合于分析裂隙岩体稳定性。介绍块体理论的基本概念和基本方法,并结合具体工程实例,运用赤平投影法分析确定失稳的块体,运用相关程序计算块体的安全系数,叙述了块体理论在边坡稳定性分析中的应用。
The block theory developed in recent ten years is a kind of analysis method for rock engineering stability, which is applicable to fissured rock stability analysis. This paper describes the basic concepts and fundamental methods of block theory. Based on specific case histories of projects, stereographic projection method is used to determine the instable blocks and relative program is used to calculate the safety factor of blocks, and the application of block theory in slope stability analysis is presented.
