摘　　要：坝后背管是一种钢筋混凝土和钢管联合受力结构,在保证压力管道承载力和结构耐久性的前提下,存在着外包钢筋用量和钢管用量分担比率的优化问题。文章利用ANSYS强大的有限元计算功能和自动优化功能,对黄河积石峡水电站压力管道进行优化分析。The penstock laid on downstream face of dam is a combined stress structure of reinforcement concrete and penstock.Under the premise of ensuring penstock bearing capacity and structure durability,the ratio of external reinforcement consumption and penstock consumption should be optimized.This paper,by use of the powerful finite element computation and automatic optimization functions of ANSYS,makes optimal analysis of penstock of Jishixia hydropower station on the Yellow River.

关 键 词：压力管道 优化设计 自动优化 有限元
