摘　　要：针对跃洲水电站泄水闸闸基地质条件较差的问题,采用结构力学法分析了泄水闸的结构和抗滑稳定性,同时应用ANSYS结构分析软件建立了泄水闸三维有限元计算分析模型,模拟了混凝土材料的弹性及岩体材料的弹塑性,分析了不同工况下泄水闸结构的应力分布情况及抗滑稳定系数,并对比了两种方法的计算结果。结果表明,跃洲水电站泄水闸应力和抗滑稳定性均满足现行规范要求,且有限元计算结果更符合工程实际。One of the problem for the sluice of Yuezhou Hydropower Station is that the poor quality of the basic geological condition.The structural mechanics method is applied to analyze the structure and stability against sliding of the sluice.And then,3-D finite element model of the sluice is established by using ANSYS.At the same time,the elastic of concrete and the elastic-plastic of the rock are simulated in detail.The stress distribution and safety factor against sliding of the sluice are analyzed under different conditions.Finally,calculation results with two methods are compared.The results show that both of the stress and stability against sliding of sluice meet current regulatory requirements;and the finite element result accords with engineering practice.
