二滩水电站引水压力管道型式研究

Study on the type of diversion penstocks for the Ertan Hydropower Station

工程建设规划设计阶段,决策者除对工程功能及效益进行研究外,还应了解当今先进施工技术,将先进技术的信息应用到工程设计中,优化设计,使工程建设更好地节约投资,加快施工进度,提高工程综合效益。以二滩水电站引水压力管道竖井和斜井两种型式为例,从地质,水能利用,施工工艺、进度等方面进行对比分析,从而得出斜管方案优于竖管方案的结论。

In the stages of project construction, planning and design, the policy maker should, in addition to the study on the project functions and benefits, understand the present advanced construction technologies and apply them to the design of project in order to make the design optimal, save the project investment, quicken the construction progress and enhance the comprehensive benefits of project. Taking two types of vertical and inclined shafts for the penstocks of Ertan Hydropower Station as examples, the comparison and analysis were made on the geology, hydropower utilization, construction techniques and progress. The results showed that the alternative of inclined shaft is advantageous over that of vertical shaft.
