【摘要】 基于节理岩体的断裂损伤模型，建立基于等效柔度张量及特定破坏准则等效体力学参数预测的方法，对节理岩体的等效力学参数进行了计算机模拟和预测，并将其应用于三峡工程坝基岩体的等效弹性参数的预测中．通过与节理刚度模型、包体模型进行比较，证明所采用模型在参数预测中较为适用，为三峡工程的坝基岩体稳定分析提供了参考．更多还原

【Abstract】 Based on a fracture-damage model, the equivalent compliance tensor and mechanics parameters for jointed rock mass are numerically predicted, and the dam-bed-rock masses of the Three Gorges Project are analyzed by this model. The comparison of this model with the other two models, joint stiffness model and inclusion model for jointed rock mass, show a good coincidence. The results are also verified by the displacement-back-analysis in the field. The simulated parameters provide a reference for the stability analysis of the Three Gorges Project.更多还原
