摘　　要：基于马堵山重力坝溢流坝段的工程地质条件建立了坝体和坝基的三维有限元模型,计算了不同工况下的应力和变形,得出了坝体的位移场和应力场,并计算了校核工况下坝基面的抗滑稳定安全系数及正常蓄水工况下坝段的安全系数。结果表明,该坝段的设计技术合理。According to the actual engineering conditions of overflow dam section,the 3-D FEM model of the overflow dam section has been built by using general program ANSYS. The stress and deformation of this dam section has been calculated and analyzed under different loads,and the stress field and displacement field have been obtained, the safety evaluation has been made. Based on the result of finite element, the sliding stability was analyzed. The anti-slide safety coefficient of the base of dam in check working conditions was 3.6. By using strength reserve method, the safety reserve coefficient was obtained. The calculation results show that the design is technically reasonable.
