Study On Seepage Prevention Reinforcement Scheme Of The Fengman Dam

Fengman dam was built in 1937, and have run for more than 60 years until now. In that specific historical condition the construction technology is very poor, honeycomb and crack appeared in the dam, and the calcareous lixiviated from the concrete, so the ant-seepage capability and the strength of the dam lowered greatly, in addition, the fault of dam have reduced the friction coefficient between the dam body and foundation , this is disadvantageous to the stability of the dam. The running condition in the past many years of Fengman dam indicated that there are serious leakage problems in the dam and the stability of the dam is deficient. So the dam is starve for seepage prevention and reinforcement measures.In this paper, existing data correlative to the problems of Fengman dam is analyzed in detail, and 3 seepage prevention and reinforcement measures are brought forward, an overall and systematic analysis is carried on from technology and economical view to the 3 measures, and the best seepage prevention and reinforcement scheme is chosen out, the scheme can solve the difficult seepage prevention and reinforcement problem fundamentally...
