摘要
本文从岩体内节理面的间距分布参数出发， 对不同大小块体的出现概率进行了分析。在分析块体的可靠度时考虑了结构面的产状、粘结系数、摩擦系数、岩体的容重等多个随机因素。并对分析过程编制成通用程序， 可以分析具体的工程设施在开挖面内不同尺寸块体的出现概率及其失效概率， 以便作为支护设计提供科学依据。
In this paper,on researching of joint face distribution distances,the appearing possibility of different dimensions of block was analyzed.Many random factors were taken into account when calculating the block reliability,such as angles of joint face,binding force,friction coefficient,the rock density,etc.The analysis process has been compiled into program and can be used for analyzing the appearing and failure probability of different dimensions of block on the excavating space of stone engineering construction.The analysis result can provide scientific basis for anchoring and sparging concrete design.
