摘要
本文根据岩体的变形破坏特性,建立了岩体脆性破坏的弱化、膨胀、侧压效应的简化模型,对巷道围岩的破坏进行了分析和评价,给出了理论解答,并由此提出合理的支护措施。
A simple model of rook failure(softening dilation and confining stress effect) is developed acording to the deformation and failure behnvior of rock. A failuretheory is given to analyse and estimate the brittle failure behavior of the rock mass around tunnel. Some useful support methods are suggested to maintain underground tunnel.
