摘要
针对马堵山重力坝冲沙孔坝段复杂的坝体结构,建立了坝体和坝基的三维有限元模型,计算了各工况下的应力和变形,分析了孔口和坝基面附近的拉应力区域并进行安全评价。根据有限元计算结果对该坝段进行抗滑稳定分析,结果表明该坝段设计合理、符合规范要求。
The sand flushing dam section of Madushan gravity dam has a complicated structure. According to the actual engineering conditions of this dam section, the 3D FEM model of the sand flushing dam section has been built by the use of general program ANSYS. The stress and deformation of this dam section has been calculated and analyzed under different static and dynamic load, and the stress field and displacement field have been obtained, and the safety evaluation has been made. Based on the result of finite element method, the sliding stability was analyzed. The calculation results show that the design is technically reasonable.
