摘要
加劲环式地下埋管的稳定是压力钢管设计中重要的问题之一,既要满足结构需要又要经济合理。文章在加劲环式地下埋管抗外压稳定设计过程中采用最优化技术解决了钢管管壁厚度、加劲环厚度及加劲环高度最优选择的难题,对加劲环式地下埋管设计的经济性取得了借鉴性成果。
Stability of the embedded penstock with stiffening ring is one of the key points in design of steel penstock. The design shall satisfy the structural requirements and be economic ＆ reasonable as well. In this paper, it describes the design of stability against ex- ternal pressure of embedded penstock with stiffening ring. In the design, the optimum technology is applied to get the optimum solution of the penstock wall thickness, the stiffening ring thickness and height. This provides the economy of the design of the ernbedded pen- stock with stiffening ring with reference.
