目前大部分水利工程由于修建时间较长,而且在使用过程中缺乏必要的维护,因此存在着各种问题。特别是一些堤坝工程,蓄水防洪能力下降,不仅严重影响了水利工程的使用性能,而且还存在着较大的安全隐患。因此需要对这些堤坝工程进行除险加固,恢复其使用蓄积水源及防御洪水的性能,有效的保护好人们群众的生命和财产安全。 At present, most water conservancy projects have various problems because they are built for a long time and lack the necessary maintenance during use. In particular, some dyke works, flood storage capacity decreased, not only seriously affected the performance of water conservancy projects, but also there is a big security risk. Therefore, it is necessary to reinforce these dikes and to restore their performance of using accumulated water and preventing floods, so as to effectively protect people’s lives and property.
