中小型水库在我国分布区域较广,数量较多,坝型多样。这些水库基本上是在上世纪50年代末至70年代中间修建,主要是为农业生产提供灌溉水源,也为人民生活用水和工业用水提供水源,同时也为防御洪水灾害发挥了一定重要作用。但是经过多年的运行使用,许多中小型水库的工程设施存在老化和损坏,不同程度地出现病险问题,汛期不敢蓄水,汛后无水可蓄,严重影响水库工程的安全运行和经济效益的发挥,威胁着水库下游人民群众的生命和财产安全,给社会造成不利因素。这些病险水库必须要采取措施进行除险加固处理,使其更好地造福社会,造福人民。
Small and medium sized reservoirs are widely distributed in our country with a large number of reservoirs and diversified dams. These reservoirs were basically constructed between the late 1950s and the mid 1970s. They mainly provide irrigation water for agricultural production, as well as provide water for domestic and industrial water use. They also play an important role in the prevention of flood disasters. However, after many years of operation and use, many small and medium-sized reservoirs have aging and damage to their engineering facilities, leading to different degrees of risk problems. They can not store water in flood season and have no water to accumulate in flood season, which seriously affects the safe operation and economic benefits of reservoir projects Which threaten the life and property safety of the people downstream from the reservoir and cause unfavorable factors to the society. These dangerous reservoirs must take measures to reinforce them to make them better for the benefit of the community and the benefit of the people.
