| 摘 要： | 采用解析法和半解析有限元法分别对鸭池河水电站埋藏式加劲压力钢管进行外压稳定性计算。在计算分析过程中,考虑了初始缺陷因素对埋藏式加劲压力钢管抗外压稳定性的影响,使得计算结果更加接近于工程实际;从而为埋藏式加劲压力钢管的外压稳定性计算提出了一种更加行之有效的方法。

| Abstract: | This paper applies analytical and semi-analytica finite element methords separately,and calculates external pressure stability of underground stiffened penstock in Yachi river hydropower station.During calculating and analysing,the effects that incipient defect factor makes on underground stiffened penstock's stability under external pressure are considered,which make the results in close proximity to engineering.This paper provides an efficient method for calculating underground stiffened penstock stability under external pressure. |
