摘要
针对鸭池河水电站地下埋管外压稳定性问题,采用半解析柱壳有限条元法、Mises法和《水电站压力钢管设计规范》(SL281-2003)所推荐的方法对地下埋管的局部稳定性、整体稳定性、加劲环的稳定性进行了计算,并通过比较分析,得出一系列对压力钢管设计有参考价值的结论,供水电站地下埋管抗外压稳定性设计参考。
This paper adopts the semi-analytical method of Cylinder-Shell Strip Finite Element Method, the Mises method, and the method recommended by The Design Specification for Steel Penstocks of Hydroelectric Stations to study the local stability, the entity stability, and the stability of the reinforcing ring of the underground penstock with the aim at the stability problem of the underground penstock stability under external pressure in the Yachihe Hydropower Station. A series of conclusions, which are valuable for the design of steel pipe with pressure, are derived through comparison and analysis. The results can provide references for the design of the penstock stability under external pressure in hydropower station.
