落生水电站压力钢管进人孔应力分析

Stress analysis of penstock manhole of Luosheng Hydropower Station

利用ANSYS有限元分析程序,分别进行了考虑人孔补强圈与主管接触或不接触两种情况下的应力计算,以此来分析接触行为对钢管开口区及补强圈应力的影响,提供落生水电站压力钢管3号人孔参考。

Using FEM Program ANSYS, the stresses around penstock manhole and in reinforcement pad are computed under the condition of considering or not considering the contact behaviour of reinforcement pad with penstock; the result is used to analyze the contact effect and the design of penstock manhole No. 3 of Luosheng Hydropower Station.
