摘要
本文通过石膏模型试验,着重分析了含定向闭合断续节理的脆性岩体的强度特性和破坏机理。在此基础上,提出了估算这种岩体强度的准则。
In this paper, the strength behavior and fracture mechanism of brittle rockmass containing oriented and closed intermittent joints are emphatically analysed by means of gypsum model tests. Based on experimental observations and theoretical analysis, the criterion for estimating the strength of such rockmasses is proposed.
