三峡左厂3#坝段深层抗滑稳定三维有限元分析

3D-FEM analysis of deep sliding stability of 3# dam foundation of left power house of the Three Gorges Project

    摘要
  • 摘要: 建立了包含基岩内大量节理裂隙和断层并且反映它们的真实产状和分布的三维有限元计算模型,研究了三峡工程左厂3#坝段的深层抗滑稳定问题,提出了一个合理实用的坝基安全系数的判断原则,给出了合理的基于强度储备概念的左厂3#坝段抗滑稳定安全系数。

     

    Abstract: 3DFEM computation model reflecting the real attitude and distribution of large structures and fault in the 3# dam foundation of the Three Gorges Project are created.The deep stability of dam foundation has been studied.A rational and practical method to judge the safety factor of dam foundation is proposed.The safety factor against sliding based on the concept of strength reserve of 3# dam foundation is given.
