摘要
鉴于进水塔结构在地震作用下的安全性关系到整个电站的安全和效益,以缅甸高震区某进水塔结构为例,采用振型分解反应谱法计算分析了进水塔结构的自振特性、动位移、动应力,并将静动力计算结果进行了叠加,评估了进水塔结构抗震性能,在此基础上分析了结构抗滑、抗倾覆稳定性。结果表明,该进水塔结构的变形、强度及稳定性均能满足要求,可为工程设计提供参考依据。
As seismic behavior of intake tower structure affects safety and benefit of the whole hydropower station under earthquake,seismic analysis of the tower is performed in Myanmar meizoseismal area.By using mode response spectrum method,the dynamic response such as natural vibration characteristics,seismic displacement and dynamic stress is discussed.Based on the superposition of static and dynamic stress results,the earthquake resistant behavior of intake tower is evaluated.Furthermore,the anti-sliding stability and over-turning resistant stability are analyzed.The results show that the deformation,strength and stability of the intake tower can satisfy requirement,which can provide reference for project design.
