本文揭示了节理岩体直剪破坏阶段的微观机理与宏观规律、剖析了机理和规律内在的形成原因与有机联系、其中、各不同局部的:“剪位移速率和剪切面两侧之间的相对位移速率”演化过程的微观差异与相互制约规律的发现与剖析,为节理岩体C、(?)峰值直剪单点法的合理性。在国内外首次从理论上解决了节理岩体直剪峰值单点法的可行性问题。
This paper reveals the micro-mechanism and macro-rule of the direct shear failure stage of jointed rock masses, and analyzes the intrinsic causes and organic connections between the mechanisms and laws, and the different parts of them: “The shear displacement rate and the shear plane between the two sides The discovery and analysis of the microscopic differences and mutual restraint laws of the relative displacement rate’s evolution process are the rationality of the peak straight shear single point method for joint rock mass C and (?). For the first time at home and abroad, the feasibility of the single point method for direct shear rock mass joints was solved theoretically.
