基于能量等效原理，建立了考虑裂隙闭合和裂隙表面摩擦效应的节理裂隙岩体本构关系，推导了柔度张量及其增量的表达式，并将该研究成果应用于三峡船闸岩体稳定性分析。计算结果表明，本模型可以较好地反映节理裂隙岩体的力学特性及开挖过程中围岩渐进破坏的规律。 Based on the principle of energy equivalence, the constitutive relation of the fractured rock mass considering the fracture closure and the frictional effect of the fracture surface was established, and the expression of the flexibility tensor and its increment was deduced. The research results were applied to the rock mass of the Three Gorges Project Stability analysis. The calculation results show that this model can better reflect the mechanical characteristics of jointed fractured rock mass and the law of gradual destruction of surrounding rock during excavation.
