摘要
基于白鹤滩水电站地下厂房排水系统结构及其特点进行可靠性分析,采用集水井集中排水的方式,结合排水量大小,充分考虑电站的长期稳定运行工况,选择型号合适的排水泵,既具备较好的排水功能,又尽量减少了岩体的开挖量.并对水淹厂房的意外应急措施进行了可行性分析,为后期运维提供充分准备,可供大型水电站地下厂房排水系统设计借鉴.
Abstract
The reliability of the drainage system for the underground powerhouse in Baihetan Hydropower Station is ana-lyzed considering the structure of the drainage system and its characteristics,in which a centralized drainage mode with collection wells is adopted.Considering the drainage amount requirement and the long-term stable operation condition of the power station,suitable type drainage pumps are selected,which not only has good drainage capability,but also min-imizes the excavation volume of the rock mass.Also,a feasibility study is carried out on the emergency measures for powerhouse flooding accident,which provides sufficient preparation for later operation and maintenance.The study can be useful reference for the design of drainage systems for underground powerhouses in large-scale hydropower stations.
