| 摘 要： | 建立了泸定水电站深孔泄洪洞高耸岸塔式进水口结构模型,并进行三维有限元动静力分析.静力计算中,分不同工况考虑了各种荷载包括绕渗作用及温度场变化的作用,得到了结构的应力与位移分布.动力计算中对进水塔结构在空库及满库情况下的自振特性进行了分析.通过振型分解的反应谱法计算了在横河流向、顺河流向和竖直向地震共同作用下进水塔结构的动力响应,并将动力计算结果与静力计算结果进行叠加.重点分析了支铰大梁、边墙、闸门槽等部位的受力特性,并对进水塔各部位的动静力稳定性进行了评价.

| Abstract: | The structural analysis model for the bank intake tower of spillway tunnel in Luding Hydropower Station is built for simulating the static and dynamic characteristics by 3D FEM.The stress and displacement distributions of intake tower in different working conditions are achieved by the static analysis after considering all loads,including the by-pass seepage and temperature change.The self-vibration characteristics under the conditions of empty and full reservoir are studied in the dynamic analysis.The dyna... |
