丰满水库水经过坝体和坝基渗透后 ,对坝体混凝土及坝基水泥帷幕产生了侵蚀 .为此 ,分析了大坝环境水的水质、库水对坝体混凝土和坝基水泥帷幕的侵蚀原理和侵蚀情况 .分析表明 ,丰满水库水质属软水类型 ,经大坝渗漏后对坝体产生溶出性侵蚀 ,多年平均坝体混凝土溶蚀约 9.6 t,坝基溶蚀约8.0 t,必须对大坝进行防渗加固 ,从根本上解决大坝受溶蚀破坏问题 .实践也证明 ,大坝防渗加固后 ,溶蚀量显著减少
After the infiltration of Fengman Reservoir and dam foundation, the dam concrete and dam foundation cement curtain have been eroded.Therefore, the water quality of dam environment is analyzed, the erosion principle and erosion of dam concrete and dam foundation cement curtain by reservoir water The analysis shows that the water quality of Fengman Reservoir belongs to the type of soft water, which causes dissolution erosion to the dam body after the seepage of the dam. The corrosion of the dam body is about 9.6 t and the dissolution of dam foundation is about 8.0 t in many years. , Fundamentally solve the problem of dam erosion and destruction.Practice also proves that dam anti-seepage reinforcement, a significant reduction in the amount of erosion
