Abstract

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.
