摘　　要：大型火力发电厂中煤的质量巨大,作用位置高,在高烈度区对整个主厂房结构产生的水平地震作用会很大,是影响主厂房结构抗震性能的主要因素之一.依据消能减震原理,将典型的火电厂混凝土主厂房的煤斗从传统连接的水平固结状态改为低水平刚度、高竖向刚度的支承式连接,即支承式煤斗.利用现有的有限元软件建立混凝土主厂房结构的弹性分析模型,同时对传统的结构形式与采用支承式煤斗减震技术的结构体系减震效果进行分析对比.There are large masses of coal in large thermal power plant which are at high position;so in the highly seismic intensity region,the horizontal seismic action on the main building structure will be very large;and it is one of the main factors affecting the seismic performance of main power building.According to the energy dissipation and vibration reduction theory,the coal scuttle of typical concrete main power building shall be changed from traditional connection with horizontal consolidation state to bearing type connection with low horizontal stiffness and high vertical stiffness,namely bearing type coal scuttle.An elastic analysis model of concrete main power building is established by using finite element software;and the damping effect of both connection types are analyzed and compared.
