摘　　要：利用ANSYS软件,用弹塑性时程分析法分析了丰镇火力发电厂采用煤斗悬吊结构与传统的煤斗支承结构在地震作用下的结构反应特点。对比分析表明,煤斗悬吊结构对减小火电厂的结构地震反应有显著的效果。The seismic properties of the structure with suspending coal hoppers and the structure with supporting coal hoppers are studied by the method of elasto-plastic time history analysis with ANSYS. Through a comparative analysis, the results show that the structure with suspending coal hoppers has a distinct effect on reducing the seismic response of the thermal power plant.
