摘　　要：火力发电厂汽机房屋盖承重结构常采用实腹式钢梁结构,但随着火力发电厂机组规模的不断扩大,汽机房的跨度也随之加大,汽机房屋面也需要有新的结构型式与之适应.以实际工程为例,详细介绍了火力发电厂汽机房三角形钢管桁架屋面的选型、构成方式及结构布置,结构计算采用空间整体计算,并进行了整体结构的稳定分析,探讨了结构的安全经济指标.供今后同类工程设计及研究人员参考.The bearing structure of steam turbine house cover in thermal power plant usually adopts solidweb steel beams.But with the enlargement of machine set scale in thermal power plants,the span of steam turbine house also increases.The steam turbine house cover also needs new structural styles to adapt to the change.Taking an actual project for example,this article expounds the structure mode,structural layout,mode selection of steam turbine house triangle steel pipe truss cover in thermal power plants in detail.The method of spatial integral calculation is adopted.The stability analysis of the whole structure has also been done.The safe and economic index of the structure is discussed,so as to affer for reference for similar engineering design and research personnel.
