电厂厂房建筑抗地震有 3个措施 :在电厂厂房建筑的底部布置弹簧隔振器 ,隔离地震中的高频激振力 ;布置粘滞阻尼器 ,消耗、吸收地震的低频能量 ;在电厂厂房建筑的高层布置调谐质量减振器TMD ,抑制地震激发振动的振幅。火电厂汽机岛厂房A列柱 ,由于刚度很小 ,不能抗地震。汽轮发电机组台板安装弹性支承后 ,台板下的立柱不再属于机器动力基础 ,而属于厂房静力基础 ,可与A列柱组成一致的厂房结构 ,增强了A列柱的刚度。这些措施在抗地震、环境振动、风振的实践中取得了很好的效果
There are three measures to prevent earthquakes in power plant buildings: the spring vibration isolator is arranged at the bottom of power plant buildings to isolate the high-frequency exciting force in earthquakes; the viscous dampers are arranged to consume and absorb the low-frequency energy of earthquakes; Of the high-level layout of the tuned mass damper TMD, suppression of earthquake-induced vibration amplitude. Thermal power plant turbine island A column plant, due to the stiffness is small, can not resist earthquakes. After the turbine generator platen is installed with elastic support, the column under the platen no longer belongs to the foundation of the machine but belongs to the static foundation of the plant. It can be consistent with the structure of the A column and enhances the rigidity of the column A. These measures have achieved good results in anti-earthquake, environmental vibration and wind-induced vibration
