| 摘 要： | 根据阀厅结构的动力特性,推导了考虑悬吊阀塔晃动离心力的阀厅结构动力计算方程,建立了有限元模型,并将深圳某换流站阀厅结构模态分析结果与实测结果进行对比,验证了模型的正确性。在此基础上,对该换流站阀厅结构体系在不同峰值、不同场地和不同方向地震波作用下,分别进行了动力时程分析。根据分析结果对换流站阀厅结构体系的地震作用效应、塔索的拉力等问题进行了探讨,为换流站阀厅结构体系的抗震设计提供依据。

| Abstract: | The finite element model for dynamic calculation of the valve hall with suspension valve tower was established,and the result of model analysis was compared with the measured result of an inverter station valve hall in Shenzhen to verify the validity of the model.On this basis,dynamic time history analysis was carried out in different peaks,different areas and different directions of seismic waves for this inverter station valve hall.According to the analysis,the seismic behavior of the valve hall and the t... |
