摘要
结合工程实例 ,介绍了两个新型的内设钢衬的大型抽水蓄能电站的尾水管造型。基于有限元法 ,分析了两个尾水管在各自最大内水压力条件下外围混凝土的受力 ,得到各自的应力变化规律和特点。通过类比分析 ,指出工程设计中的不足 。
By analyzing two engineering projects, two kinds of new configuration of draft tube with steel shape inside of large-scale pumped storage power plant are discussed. Stress of surrounding concrete of each draft tube is analysed by the finite-element method under condition of the highest hydraulic pressure and the variable regularity of stress is obtained. Finally, the results of computation are compared and the deficiency in design is discovered and some valuable conclusionsare drawn.
