摘　　要：用三维有限单元方法 ,对国外某水电站地下厂房的环梁三立柱式异型机墩及风罩、厂房墙体、楼板梁系统所组成的整体结构进行了动静力分析 ;对厂房内各种振源频率与支承结构固有频率间的耦合共振情况进行了校核 ,结果表明 。Through the 3D finite element method, the dynamic numerical analysis is performed in this paper on the whole system of the underground hydropower house located abroad, which is composed of a circle beam with three abnormal columns, bellows, walls, floors and beams. It also makes a resonance verification of the interrelationship between varient frequency of the vibration sources in the powerhouse and the natural frequency of the supporting structure. The results indicate that the dynamic design of the abnormal supporting structure of the turbine units is feasible.
