摘要
三道湾水电站位于甘肃省讨赖河上,水电站压力管道为地下埋管,设计水头达372.72 m。根据该工程的实际,建立了岔管及其围岩的三维有限元模型。采用钢岔管和围岩联合承载的设计原则,计算分析了在设计内水压力作用下,不同钢岔管管壁厚度和衬砌结构对应的钢岔管及外包混凝土的应力状态,选择了合理的钢岔管管壁厚度;最后复核各种工况下钢岔管的应力状态,证明钢岔管和衬砌推荐方案满足规范要求,成果可供设计和施工参考。
The Sandaowan Hydropowcr Station is located on the Taolai River in Gansu Province, and the penstock of station is buried underground with a design head of 372.72 m. The three-dimensional finite element model for stress analysis was established. The stresses nf bifurcation and surrounding concrete under design pressure and on the conditions of ,Jarious bifurcation thicknesses and lining structures were calculated surrounding rock. The thickness of bifurcation was selected based on the combined bearing principle of bifurcation and according the calculation and the stresses were checked for different operating conditions. The results show that the recommended scheme of bifurcation and lining meets the requirements of specifications and can be as retrence to engineering design and construction.
