It plays a decisive role in whether the whole reservoir dam can effectively retain water. The quality of its system will directly affect the success or failure of the whole project. Aiming at the problems such as low flood control standard of a reservoir's homogeneous dam, large-area swamping of downstream dam slope, local water and sand leakage of the dam body, according to the results of core drilling sampling and safety appraisal analysis, combined with the dam's disease risk status and dam type structure, the risk removal and reinforcement scheme combining 0.7m increase in dam crest thickness with backfilling clay of drift-grab casing wells is optimized.展开更多
