摘　　要：针对富水水库存在的坝坡塌陷、渗漏严重等安全隐患,采用干砌石、预制板稳固、垂直混凝土防渗墙等方法对坝坡进行除险加固。依据简化毕肖普理论通过AutoBANK有限元模拟方法,分别对坝体及心墙在校核洪水位、设计洪水位、正常蓄水位等不同运行工况下的稳定性分析表明,各运行工况下的坝坡稳定性均满足规范要求,可作为大坝的加固设计、施工和后期运行管理的依据,并建议在大坝的运行中加强监测。Safety risks such as dam slope collapse and severe seepage are observed in Fushui Reservoir.Thus,technical measures such as dry masonry,precast slab stabilization,and vertical concrete cutoff wall are used to reinforce the dam slope.Based on the simplified Bishop theory,AutoBank finite element simulation software is adopted to analyze the stability of the dam body and the core wall under different working conditions such as the check flood water level,design flood water level,and normal storage water level.The results show that the stability of the dam slope under various working conditions meets the specification requirements,which can provide useful basis for the reinforcement design,construction and later operation management of the dam.Also,it is suggested to strengthen the monitoring work during the operation of the dam.
