摘　　要：为探讨岩石的残余强度与围压的关系,本文通过选取适当的模拟函数模拟二者关系,建立基于SMP破坏准则的残余强度与围岩的关系,并通过矽卡岩和大理岩两种岩石的试验结果进行分析,研究表明:该方法较目前采用的Mohr-Coulomb和Hoek-Brown两个准则所建立的残余强度与围岩关系更能合理解释试验结果。In order to explore the relationship between the residual stress and the surrounding rock pressure,selecting the appropriate functions simulate the relationship between the two,and then established the fitting function based on SMP failure criterion,analyzed its applicability,through analyzed the experimental results of the skarn and marble,show this method can explain the relationship of the residual strength with the surrounding rock more reasonable.

关 键 词：SMP准则 残余应力 围压
