摘　　要：对后浇带区域受力性能及临时独立支撑布置方法进行了研究.首先基于力学原理建立后浇带区域变形的计算模型,根据规范取后浇带所在跨跨度的1/1000作为支撑布置的挠度控制指标,推导出支撑布置计算判据,以此判定需要布置支撑的后浇带区域,提出后浇带临时支撑布设方案;然后总结支撑布置规律,给出支撑布设位置速查表;最后以具体工程为例验证所提出的支撑布设方案的适用性.A study was conducted on the load-bearing performance and temporary independent support arrangement method of the post-cast strip area.Firstly,a calculation model for the deformation of the postcast strip area was established based on mechanics principles.A deflection control index for support arrangement was derived by taking 1/1000 of the span where the post-cast strip was located according to specifications.A calculation criterion for support arrangement is proposed to determine the post-cast strip area that requires support.Then,a temporary support arrangement plan for the post-cast strip is presented.The rules for support arrangement are summarized,and a quick reference table for support placement is provided.Finally,a specific project was used as an example to verify the applicability of the proposed support arrangement scheme.This study provides insights into improving the design and construction of post-pouring belt structures.
