摘　　要：电力行业中的大型贮煤筒仓均为钢筋混凝土结构,其顶盖型式对工期、造价和结构安全都有很大影响。对筒仓顶盖采用现浇混凝土和钢梁现浇板等3种不同方案在工期和造价方面进行了对比分析,给出了详细的施工方案和造价清单,得出了采用钢梁现浇板方案是最优方案,为今后工程设计提供借鉴。As an important structure for coal storage in thermal power plants,silo has been widely used due to their unique advantages.At present,the large coal silos in the electric power industry are all reinforced concrete structures,and the roof type has a great influence on the construction period,cost and structural safety.This paper conducts a comparative analysis of the construction period and cost of three different schemes,which adopts cast-in-place concrete or steel beam cast-in-place slab for the silo roof.The detailed construction scheme and cost list are also given in this paper.lt is concluded that the steel beam cast-in-place slab scheme is the optimal scheme and can provide a reference for the future engineering design.
