The Earth Dam's Design And The Safety Evaluation On Hefei Dafangying Reservoir

Though the analysis and research on the technique of the earth dam's construction and according to the design standard concerned, this paper explores the earth dam's design and the safety evaluation on Dafangying reservoir. The major dam's design of the reservoir includes engineering program and engineering design. The engineering design is about major dam's structure, reconnaissance of the earth material spot, pressure standard of the dam ,dealing with the foundation of the dam and the through dam buildings. On the basis of the different working status, the dam's seepage, stability and sinking should be figured. In construction unit examines by itself, supervision make a random spot check on the quality of the fill before the construction be completed. The scientific research unit makes a appraisal of safety about the construction before storage ok water. According to the data tested on the construction quality and the data observed during the dam works, the structure of the dam should be made safety evaluation.
