我国是世界上拥有土石坝最多的国家之一,其中中小型水库大坝绝大部分是土石坝。土石坝工程在防洪抗旱中发挥了重要的作用,促进了工农业生产,提高了人民生活水平。但由于当时特定的历史条件,存在严重的边勘测、边设计、边施工现象,防洪标准低,质量控制不严,尾工和隐患较多,时刻威胁下游人民生命财产安全,限制了当地的经济发展,其除险加固的重要性和必要性为人民所认识,各地都在进行病险水库的除险加固。而搞好病险水库的除险加固,必须搞好除险加固设计。本文结合工程案例,对中小型病险水库除险加固技术进行了探讨,希望对同类型工程起到参考作用。
China is one of the countries with the largest number of earth-rock dams in the world, of which the vast majority of small and medium sized reservoir dams are earth-rock dams. Earth-rock dam project has played an important role in flood control and drought relief, promoted industrial and agricultural production and raised people’s living standards. However, due to the specific historical conditions at the time, there were serious side surveys. The problems of design, construction, low flood control standards, unscrupulous quality control and more tailgating and hidden dangers existed at the moment, threatening the life and property safety of downstream people and limiting the local economy Development, the importance and necessity of its reinforcement and reinforcement are recognized by the people, and the reinforcement and reinforcement of dangerous reservoirs are taking place all over the country. And do a good job dangerous reinforcement of dangerous reservoirs, we must do a good job reinforcement design. In this paper, combined with the project case, the reinforcement of small and medium-sized dangerous reservoirs were discussed, hoping to play a reference for the same type of project.
