抽水蓄能电站地下工程主要包括地下厂房系统和输水系统两大部分。而输水系统采用斜井还是竖井布置方案,主要取决于工程地形、地质条件和枢纽总体布置要求。斜井方案可减少管道长度,降低工程造价,但斜井方案对围岩的地形、地质条件要求较高。现对斜井施工技术进行了分析和研究。 Pumped storage power station underground works include underground powerhouse system and water system two major parts. The inclined waterway system or shaft arrangement, mainly depends on the project topography, geological conditions and hub layout requirements. Inclined shaft program can reduce the length of the pipeline and reduce the cost of the project, but the program of the inclined shaft has high requirements on the topography and geological conditions of the surrounding rock. Inclined shaft construction technology is analyzed and studied.
