Jiangkou Brook Reservoir is a small (two) reservoir that is mainly irrigated and has the integrated functions of rural drinking water and other functions. Among them, the dam is a masonry arch dam and has been identified as three types of dams. Threatening the downstream property and life safety, so need to reinforce. After identifying the causes of reservoir diseases, the author analyzed the characteristics of the reservoir and made a comparison and selection of the design schemes of reinforcement and danger elimination. Finally, the design scheme of “overflow dam 2.5m higher” was selected, After the water storage operation proved that the recommended scheme was reasonable and reached the purpose of reinforcement and reinforcement.
