大跨结构单个临时支撑卸载的施工内力分析

摘要

对大跨结构单个临时支撑的卸载过程进行了研究,并对其的施工内力进行了分析,比较目前常用的两种分析模型的有限元计算结果,探讨了不同的卸载时间和加载方式对施工内力的影响,得出了有指导意义的结论。%The paper researches the unloading process of the single temporary support of the large-span structure,analyzes the internal force in the unloading process of the single temporary support,compares the finite element calculation results of the common two analysis models,explores the influence of the different unloading time and the uploading ways on the internal force of the construction,and concludes some structure with direction significance.
