本文讨论了当α>αmax,沿结构面发生纵向张裂时岩体的强度大小,并绘出其强度曲线;根据等效原理给出了岩体沿结构面张裂时的强度公式,它们均为结构面方向角α的函数。从而可定量判断在其结构面方向与最大应力方向接近一致时的稳定性。
This paper discusses the strength of rock mass when α>αmax occurs along the plane of longitudinal cracking and plots its strength curve. According to the equivalence principle, the strength formula of rock mass along the structural plane is given. It is a function of the structural plane direction angle α. Thus, the stability can be quantitatively judged when the direction of its structural plane is nearly the same as the direction of maximum stress.
