摘　　要：以呼和浩特抽水蓄能电站地下厂房为例,建立了考虑不同范围围岩的水电站地下厂房三维动力有限计算模型,分别在不同频率的内源动荷载作用下系统分析了围岩范围对水电站地下厂房动力特性的影响。计算结果表明,该模型的建立考虑一定范围的围岩是合理且必要的,可为水电站建模提供借鉴。Firstly,based on the background of Hohhot pumped storage plant,six dynamic simulated-models for the underground hydropower house were set up with various range of surrounding rocks. Then, the influence of surrounding rocks on the dynamic response of underground hydraulic power station was studied under the action of five kinds of frequency internal dynamic loadings separately. Numerical results indicate that it is reasonable to consider the influence of surrounding rocks once the dynamic features of underground hydropower house were studied under the action of internal dynamic loadings. The conclusions of this work could be used as a primary guidance to the setting up of dynamic simulated-model for underground hydropower house.
