| 摘 要： | 大型钢结构建设所需要的临时结构规模也比较大，在永久结构吊装和临时结构拆撑过程中，永久结构和临时结构的内力和位移都会不断地发生变化，而施工力学的预跟踪分析可以为实际施工过程提供指导．但是当永久结构和临时结构的规模较大时，会造成计算和分析的诸多困难，如何对临时结构进行准确地简化分析是解决问题的关键．本对如何简化支撑、如何考虑弹簧的耦合影响进行了分析．

| Abstract: | Large temporary supporting structures are needed during the construction process of large span steel structures. The internal forces and deformation of permanent structures and temporary structures will be variable during the erection of steel structures. And the mechanical analysis can guide the real construction procedure. When the temporary structures are large and complex the analysis of construction process will be difficult. The simplified analysis solution method is given in this paper and the way to simplify the supports as well as the effect of spring is analyzed. |
