After site survey and exploration, the recommended type of dam is rockfill concrete arch dam, considering the treatment measures of dam foundation shoulder, slope excavation and support method, seepage control treatment method of dissolution zone, layout of key components (dam, drainage building and water collecting and releasing facilities), project investment and economic benefits, etc. The dam structure is designed according to the Design Code for Concrete Arch DAMS SL282-2018. The analysis results show THAT the stress OF dam body under various working conditions is within the allowable range stipulated in the code, and the bearing capacity of bedrock meets the requirements.展开更多
