摘要： 以四川木里河立洲水电站调压井工程为研究对象，对围岩稳定及衬砌结构内力分布与配筋等开展了较为深入系统的研究。通过ANSYS软件二次开发，利用APDL编制调压井任意断面的内力计算程序，对不同工况典型断面进行内力分析，获得了井筒沿高程内力分布图，对施工工况（锁口衬砌段）、运行工况（最高涌浪控制工况下井筒衬砌和底板配筋）提出了调压井衬砌结构的配筋建议。

Abstract: This research was to investigate the surrounding rock stability, inner force distribution, and reinforcement of the surge tank lining of Lizhou Hydropower Station on Muli River in Sichuan Province of China. Through secondary development of ANSYS by compiling a calculation program with APDL (ANSYS Parametric Design Language) for the inner force of arbitrary section of the surge tank, the inner forces of the lining structure of the surge tank under different working conditions were analyzed. The distribution map of inner force along the shaft elevation was acquired. Suggestions were proposed for the reinforcement of surge tank lining structure in construction period(fore shaft lining segment) and operation period(shaft lining and base slab reinforcement in loading-control case under maximum surge). The verified width of maximum crack of the lining didn’t exceed the allowable limit, which proved the rationality of the structure and the reinforcement design of the surge tank.             

Key words: secondary development of ANSYS, 3-D finite element, inner force calculation, lining reinforcement
