［摘要］对保定垃圾焚烧发电工程主厂房结构采用时程分析法进行地震反应分析研究，并对动力特性、位移、加速度等计算结果进行分析。厂房由于设有垃圾储存池造成结构刚度在平面、立面都不均匀，且纵向较横向严重，会产生较大的扭转，不利于抗震。垃圾焚烧工程主厂房结构的抗震设计应合理选择结构布置方案，采用多个空间有限元分析程序，合理选择参数进行分析。通过控制振型、结构位移等计算结果来控制结构的扭转，并适当提高抗震措施。

Abstract:The seismic response of the structure system of Baoding refuse incinerating power plant is analyzed and studied by time history analysis method. The calculation results of dynamic properties, displacement and acceleration are concerned. Due to refuse bunker, the stiffness of plant structure is irregular in plane and elevation and the longitudinal direction is more serious than the transverse direction. It makes large torsion and its seismic behavior is poor. The seismic design of main building structure of  refuse incinerating power plant should have reasonable selection of structure arrangement scheme, use several special finite element analysis program, select reasonable parameters, control the torsion of structure by controlling calculation results such as vibration mode, displacement and so on and enhance seismic fortification measures properly.
Keywords:refuse incinerating power plant; frame-bent structure; seismic design point; time history analysis
