溧阳抽水蓄能电站上水库竖井式进/出水口设计

摘要

溧阳抽水蓄能电站上水库进/出水口为竖井式,具有结构复杂、规模庞大、地质条件较差等特点.采用数值分析方法对各设计方案进行了分析比较,并对选定的方案进行了水力模型试验验证,设计选用的体形具有较好的水力条件；进/出水口塔体上部采用框架结构,并采用无拦污栅的设计方案；通过扩大基础直径,增强结构抗倾覆稳定及地基应力的要求,解决了水力学、结构设计和基础处理等方面存在一系列的技术难题.%The inlet/outlet of upper reservoir in Liyang Pumped—storage Power Station is shaft—type with complex structure, large scale and poor foundation geological condition. Different design options of inlet/outlet are compared by numerical analysis method and the selected design option is tested by hydraulic model. The final design option has better hydraulic structure. The frame structure is chosen for the upper body of inlet/outlet tower and there is no trashrack in design. The stability against overturning and the requirements on foundation stress are met by expanding base diameter of inlet/outlet. These measures solve a series of technical problems in hydraulic design, structure design and foundation treatment of inlet/outlet.
