龙羊峡水电站厂房的抗震(振)研究

The Research of Earthquake Resistance of the Factory Building about Long Yang Xia Hydro - Power - Plant

对龙羊峡水电站整体厂房、单机组段厂房分别进行抗震研究;并对单机组段厂房进行模型试验;考虑到水轮机的转频与单机组段厂房基频接近,对原设计方案进行修改,使厂房基频与水轮机转频错开,避免共振现象发生。

The Researches of earthquake resistance (vibration proof) of factory building in globe type and single machine groupsection about Long Yang Xia Hydro - power station were carried out respectively, and model experiment of workshop of single machine group section has been made. Comparing the results of experiment with that of computation, good correspendence is found. In order to prevent the turning frequency of hydroturbine with the base frequency of a single machine group section workshop from common vibrating, the original design and model has been corrected. So that the common vibration can be avoided.
