摘　　要：某大型火力发电厂烟囱结构中采用大跨度圆环形简支板。原设计方案为钢筋混凝土板,后改为钢-混凝土组合板。利用有限元程序对钢筋混凝土板和钢-混凝土组合板两种设计方案进行计算分析和对比,说明钢-混凝土组合板应用于大跨度不规则板结构的优点和经济指标。工程实践表明,应用效果良好。The design and analysis of long-span cirque simple supported slab are introduced in a chimney construction. The reinforced concrete slab is used in the original design and then replaced by the steel-concrete composite slab. Finite element method is used to analyze reinforced concrete slab and steel-concrete composite slab, and the cost of materials is compared. The analysis results reveal that steel-concrete composite slab has advantage over reinforced concrete slab when used in longspan and special slab structure.
