浅析断裂力学法确定岩体强度参数

Analysis of Fracture Mechanics Method to Confirm Strength Parameter of Rock Mass

推导了岩石强度准则的材料参数和断裂理论的断裂韧度存在的特定方程关系,并以岩石压剪试验为例,说明该推导的合理性。

A specific equation relationship exist in between material parameters of rock strength criterion and fracture toughness of fracture theory is derived, and rationality of this derivation is proved by the example of rock＇s compression shear.
