摘要
汾河一坝枢纽滚水坝存在渗透稳定与上游铺盖首端防冲问题,设计中首先对滚水坝现状渗透稳定及首端冲刷进行了复核计算,根据计算结果,提出了在上游设置钢筋混凝土水平铺盖及垂直钢筋混凝土防渗、防冲墙方案,并经过分析计算,认为该除险加固方案是有效合理的。
For the Fenhe NO.1 Hydraulic Project, there are two problems in the overflow dam＇s founfation： seepage stability problem and erosion problem at the upstream foundation head.In the design process, at first ,the calculation to check the seepage stability of the dam＇s status quo and the erosion situation of the upstream foundation head was conducted.According to the calculation results,a scheme to solve these problems was put forward.It is to establish a horizontal reinforced concrete blanket and a vertical reinforced concrete diaphragm on the upstream dam toe.Through analysis and calculation, it is considered that this scheme is effective and reasonable.
