假设脆性材料的强度满足Ｗｅｉｂｕｌｌ分布．本文结合莫尔－库伦定理和统计断裂力学对任意压应力状态下脆性材料的断裂行为进行了研究，得到了一些有益的结论。

Study on the Theory of Statistical Fracture at Pressure Stress-states Zhu Nailong; Zhang Jiru (Institute of Architecture &. Civil Engineering,WUT,Wuhan 430070,Chiha)Assumimg the strength of brittle materials is satisfied for weibull's distribuion, the fracture behaviour of brittle materials at any prssure stress-states is studied by means of combining Mohr-coulomb's theory with statistical fracture mechanics some results have been obtained.: failure probability; the effective stress; statistial fracture theory ; Mohr-coulomb's law
