岩滩水电站扩建工程排水系统设计优化

Optimization Design of Dewatering and Drainage Systems of Yantan Hydropower Station Extension Project

岩滩水电站扩建工程为地下式厂房,检修排水系统和渗漏排水系统从可研到施工图阶段经过了多次的优化研究工作,最终的设计考虑了经济性、安全性、扩建工程的地下厂房的特性及规范对于防止厂房倒灌被淹的要求。目前全部排水系统已通过验收并运转良好,证明了整个设计优化过程取得了预期的效果。

Yantan hydropower station extension project has an underground powerhouse, for which the dewatering and drainage systems were optimized for many times from the feasibility study stage to the detailed design stage in consid-eration of the economy, the safety and the characteristics of the extended powerhouse as well as the code requirements on powerhouse flooding due to backward flow. By far, all the dewatering and drainage systems run very well after been accepted, which proved that the optimization design gets the desired result.
