摘　　要：随着开采深度的进一步增加，软破岩工程变得越来越突出。本文在分析软破岩石特点的基础上，提出了依据软破岩石三轴试验，而建立其破坏准则，为对软破岩的进一步深入研究提供了条件，同时为岩石强度的研究开辟了一条实用途径。With the deepening of the mining engineering, the soft-broken rock has become more and moreimportant. The paper presents the failure criterion of soft-broken rock based on the analysis of a few features andthe triaxal test of soft-broken rock. The study of failure criterion for soft-broken rock is the most practical way toresearch the theory of rock strength.
