【摘要】：某电厂封闭式煤场钢结构,跨度200m,长度240m,矢高为42m,为大跨度煤场封闭结构。从单元受力、剖面形状、荷载、设计参数、预应力影响等多方面论述了超大跨度结构的设计选型问题,并对结构进行风荷载作用、地震作用、支座位移影响及整体稳定性进行了分析,最后提出了超大跨度煤场结构设计中的几点建议,为超大跨度煤场结构的推广应用积累了一定的经验。
[Abstract]:The enclosed coal yard steel structure of a power plant has a span of 200m, a length of 240m and a vector height of 42m. it is a large-span closed structure of coal yard. From the aspects of element force, section shape, load, design parameter, influence of prestress and so on, this paper discusses the design and selection of super-span structure, and carries on wind load and earthquake action to the structure. The influence of support displacement and overall stability are analyzed, and some suggestions in the design of super-span coal yard structure are put forward, which have accumulated some experience for the popularization and application of super-span coal yard structure.
