摘要
运用弹塑性断裂力学的裂纹线场分析方法，将描述岩体材料破坏特性的摩尔－库仑准则，列入求解岩体内节理断裂问题的基本方程中，对节理裂隙在压剪荷载下进行求解，得出了节理线附近的弹塑性区应力场。通过弹塑性场在其边界上的匹配条件，得出了节理线上塑性区长度与压剪荷载的关系。
In this paper the elastoplastic stress fields near joint line in rockmass loaded by compress- shear are analyesd by the line field method in fracture mechanics with Mokr- Coulomb criterion. Through the matching conditions of the elastoplastic fields on their boundary, the relations between the length of plastic zone on the joint line and the compress- shear loads are found, and the fracture criterion of the discrete joint is also obtained
