广西龙江叶茂水电站1997年建成,是龙江梯级电站中的一级。2010年根据国家电力监管委员会大坝安全监察中心安全监察处对叶茂水电站大坝安全首次定期检查的要求,需要对叶茂水电站大坝的设计进行复核。文章选取叶茂水电站溢流坝1#边墩、3#中墩作为复核对象进行闸墩结构安全复核,采用ANSYSl0.0软件进行结构空间有限元分析,复核闸墩结构位移、应力与配筋以及总结挡水设计高度在10~15 m时此类闸墩在配筋设计的共性与差异。
Guangxi Longjiang Yemao hydropower station built in 1997, is one of the Longjiang cascade hydropower station. According to the requirements of the first regular inspection of the dam safety of the Ye Mao Hydropower Station by the Safety Supervision Department of the State Electricity Regulatory Commission’s Dam Safety Supervision and Inspection Center in 2010, the design of the Yemao Dam needs to be reviewed. In this paper, 1 # side pier and 3 # middle pier of overflow spillway dam of Yemao Hydropower Station are selected for safety review of pier structure. ANSYS 1.00 software is used to carry out structural space finite element analysis to review the displacement, stress and reinforcement of sluice pier and Summarize the commonality and difference of such pier design in reinforcement design when the height of retaining design is between 10 m and 15 m.
