我国的小(1)、小(2)型水库数量众多,多分布于丘陵山区,坝型以均质土坝居多,水库的修建主要为农业生产和人民生活用水提供方便,同时也为防御洪涝灾害的发生起到了一定调节和保护作用。早在20世纪五六十年代修建的小型水库,由于当时的地理环境及施工条件较差,造成工程质量较低,建成后在运行过程中问题突显,严重威胁下游人民群众的生命财产安全,成为安全隐患。为此,国家加大投资力度,对病险水库进行加固维修,以消除其不安全因素,使其发挥除害兴利的作用,更有效的服务于社会,服务于大众。 There are a large number of small (1) and small (2) reservoirs in our country, which are mostly distributed in hilly and mountainous areas. Most dam types are homogeneous soil dams. The reservoir construction mainly provides convenience for agricultural production and people’s daily life, Occurrence of disasters played a role in regulation and protection. As early as the 1950s and 1960s built small reservoirs, due to the current geographical environment and poor construction conditions, resulting in lower quality of the project, after the completion of the operation in the process of highlighting the problem, a serious threat to the lives of the people downstream property safety, a Security risks. To this end, the state has increased its investment to reinforce and repair diseased reservoirs in order to eliminate their unsafe factors, make them play a role in eliminating and reducing risks, serve more effectively the society and serve the public.
