摘要
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 equivalent energy theory, the anisotropic damage constitutive model of jointed rockmass is set up with joint closing and joint surface friction considered. The compliance tensor and its increments are deduced. The model is applied to analyze the stability of high ship-lock slopes of Three Gorges, and the results show that the model is satisfied in simulating mechanical properties and progressive failure of surrounding rock mass during excavation.
