摘要

通过对某水电站西宁出线楼分顺水水平向为主的地震作用和垂直于顺水水平向为主的地震作用两种工况进行三维有限元结构动力分析,得到了该出线楼在地震作用工况下自振频率的变化规律、屋顶和设备层的位移及变形结果,并对变形进行了验算。结果表明,该出线楼在当地多发地震作用下是安全的,能满足该出线楼的安全运行。
Based on dynamic analysis of three-dimensional finite element method,the 750 kV outlet-building of some hydroelectric power station was analyzed by two seismic loadcases,one was mainly the seismic action along the direction of flow,the other is mainly the seismic action vertical to the direction of flow.The change law of natural frequency and the displacements and deformation results of the roof and equipments layer of the outlet-building were obtained.Meanwhile,the checking calculation of the deformation had been done.The results showed that the outlet-building was safe under the action of local frequent earthquake and could meet its safe operation.
