天桥水电站扩泄除险方案分析

Schemes Analysis of Extending Flux for Wiping off Danger of Tianqiao Hydropower Station

天桥水电站工程地质和水文地质条件非常复杂,在考虑原建筑物布置和地形地质条件的情况下,选择了新增泄洪建筑物的位置,且在考虑工程投资、电厂运行管理、新增建筑物进流条件、弃水量及泄洪排沙等因素的情况下,推荐了几种扩泄除险方案,并进行了方案之间的比较,从中选取了最优方案,达到了提高防洪标准的目的.

Tianqiao Hydropower Station＇s geology of engineering and hydrology are very complex. Considering the location of the old building and the terrain ＆ geology conditions, the locations of new extending flux building are selected, and considering the investment of this engineering,the power station running management, the conditions of new building entering flow,the abandoning,water＇ s quantity,flood discharging and draining off sand, and so on, several schemes of extanding flux for wiping off danger are recommended, and comparing with these schemes,the most optimizative scheme is chosen in the end. this design is valuable for the other engineering of extending flux for wiping off danger.
