摘　　要：大直径筒仓是一种大空间新型钢筋混凝土筒仓,仓顶盖多采用圆锥壳结构形式。为适应南方防雨、设备防护、隔热等问题,结合实际工程,提出一种适用于大直径筒仓的双层顶盖空间结构形式。基于有限元模拟,对其施工阶段和正常使用阶段两种工况下的力学性能进行数值分析,揭示其受力机理,优化结构设计方案,提出了双层顶盖的计算要点和设计建议。As a common new type of silo with large diameter,the silo top mostly adopts cone-top structure.In order to solve the problems of difficult construction and long period,a double roof space structure for large diameter silo is put forward.Based on the finite element simulation,the mechanical properties of the double roof under the construction stage and the normal use stage are numerically analyzed,the stress mechanism is revealed,the structural design scheme is optimized,and the calculation points and design suggestions are put forward.
