摘　　要：为了研究多层模板支撑体系荷载传递规律,探究多层模板支撑架在一个完整施工周期内的最不利荷载,对青岛某工程模板支撑系统内若干楼层支架立杆轴力进行长期监测。通过对监测数据的统计分析,得出了支撑架立杆轴力在一个周期内的变化规律,说明了支撑架立杆承担的最不利荷载出现在上一楼层顶板浇筑混凝土时,通过定量分析给出了顶层施工荷载向各层楼板及支撑架的传递比例。In order to study the load transfer law of multilayer formwork supports system,and explore the most unfavorable load of multilayer formwork support in a complete construction period,we have long term monitoring of the shaft force of the support bar of a project in Qingdao.Through the statistical analysis of the monitoring data,it is found that the variation of the axial force of the support frame in a cycle.It shows that the most unfavorable load of the support frame appeared in the upper storey roof pouring concrete.Through the quantitative analysis,the transfer ratio of the top construction load to the floor and the support frame is presented.
