摘　　要：悬吊结构是一种理论技术成熟的抗震结构形式,将煤斗采用悬吊方式设置以改善电厂厂房结构的抗震性能是一项新的大型火电厂结构措施。利用ANSYS有限元分析软件,用反应谱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 suspending structure is mature in theory and technology,and the structural system of suspending coal hoppers is an innovative structural shape in engineering design for a large-scale thermal power plant.The seismic properties of the structure with suspending coal hoppers and the structure with supporting coal hoppers are analysed by the method of response spectrum method with ANSYS.Through a comparative analysis,the results show that the structure with suspending coal hoppers has a remarkable effect on reducing the seismic response of the thermal power plant.
