摘　　要：通过多种结构方案的比较,研究了200m以上超大跨度干煤棚结构的设计选型,得出超大跨度干煤棚的适宜结构形式。依据国家规范及建设方使用功能要求,确定干煤棚结构的荷载作用和设计控制指标要求,在此基础上对结构进行设计选型。通过多种方案比较确定预应力拉索形状、预应力施加控制原则及最优柱距;最后通过存煤效益比较,得出最优跨度。结果表明:大跨度索拱桁架结构的各项技术经济指标均表现良好,适宜在200m以上跨度的干煤棚结构中采用。Through the comparison of various structural schemes,the design and selection of the super-long span dry coal shed structure of more than 200 m was studied,and the suitable structure form of the super-long span dry coal shed was obtained.According to the national regulations and the functional requirements of the construction party,the load function and design control index requirements of the dry coal shed structure were determined,and the structure was designed and selected on this basis.The shape of the prestressed cable,the principle of prestressing control and the optimal column spacing were determined by comparing various schemes.Finally,the optimal span was obtained by comparing the benefits of coal storage.The results show that the various technical and economic indicators of the large-span cable-arch truss structure perform well,and it is suitable for use in the dry coal shed structure with a span of more than 200 m.
