摘　　要：对大跨度干煤棚结构设计来说,在保证安全的条件下,如何更好地控制用钢量,达到最优经济效果是工程各方最关心的问题。本文以新疆某地区工程超大跨煤棚网壳的设计优化中网壳合拢温度区间的最终确定的过程为例,探讨温度应力对干煤棚结构的影响及其作用的减小措施。In the structural design of long-span dry coal shed,under the condition of ensuring safety,how to better control the steel consumption and achieve the optimal economic effect is the most concerned problem of all engineering parties.Taking the intermediate process of the final determination of the closure temperature range of the reticulated shell in the design optimization of the super large span coal shed reticulated shell of a project in Xinjiang as an example,this paper discusses the influence of temperature stress on the dry coal shed structure and the reduction measures of its effect,and puts forward some suggestions for the dry coal shed structure design of the site with large temperature difference.
