【摘要】 本文根据Ｂｅｔｔｉ能量互易定理，节理岩体能量损伤演化方程，广义正交法则和塑性损伤一致性条件建立了节理岩体的能量损伤本构模型，并将该模型编制成三维非线性有限元计算程序应用于溪洛渡地下厂房洞室群施工开挖稳定性分析，获得了较为满意的计算结果。更多还原

【Abstract】 According to the Betti’s reciprocal energy theorem, energy damage evolution equation of jointed rockmass, generalized normal flow rule, and consistent condition of plastic damage, A 3 D constitutive model for energy damage of jointed rockmass is firstly constructed in this paper. Then a 3 D Nonlinear FEM Computation program about the constitutive model has been programmed, Finally we apply the program to underground power house of XILUODU hydroelectric station to Carry out Stability analysis under excavation and get some satisfactory computation results.更多还原
