本文建立了断续裂隙岩体的三维弹塑性损伤本构模型，并将该模型应用于三峡船闸高边坡，进行了边坡开挖弹塑性损伤三维非线性有限元计算，获得了一些有益的成果和结论． In this paper, a three-dimensional elastic-plastic damage constitutive model for fractured rock masses has been built. The model has been applied to the high slope of the Three Gorges Project. Three-dimensional nonlinear finite element calculations have been carried out for the elastoplastic damage of excavation. Some useful results And conclusion.
