摘要
采用有限元计算软件建立了丹东水电站的钢筋混凝土岔管及发电机组的三维有限元模型,分析计算了各种铁路桥荷载及其组合作用下钢筋混凝土岔管及发电机组的应力增量.结果表明,钢筋混凝土岔管及发电机组的应力增量较小,故月山车站改建工程对丹东水电站强度影响较小,不会对水电站的安全运行带来威胁.
The FEM software were adopted to establish the 3D mod el of reinforced concrete penstock and generating set of Dandong hydroelectric power station,and its stress increments under each railway bridge load and combination effects were calculated.The result indicated that due to the the stress increments of reinforced concrete penstock and generating set was smaller,the influence of Yueshan station rebuilding project on Dandong hydropower station was smaller,which wouldn′t threaten the safety operation of Dando ng hydroelectric power station.
