| 摘 要： | 为了探讨溶洞对压力管道的影响，结合西龙池抽水蓄能电站实际工程,采用有限元方法对其进行了弹塑性有限元数值计算，并根据计算结果对溶洞大小、距离与压力管道最大主应力、最大位移以及稳定性之间关系进行了分析。研究结果表明：溶洞大小和距离对压力管道最大主应力和最大位移将产生明显的影响。

| Abstract: | In order to discuss the effect of melt hole on steel penstock and in combination with the practice of the Xilongchi Pumped-storage Power Station, the author adopts the elastoplastic FEM to make numerical calculation and analyzes the relationship between the size and distance of melt hole and the maximal principal stress and the maximal displacement and stability of steel penstock based on the results. The findings indicated that the maximal principal stress and the maximal displacement of steel penstock be influenced obviously by the size and distance of melt hole. |
