摘要： 通过现场实测施工期混凝土结构,来把握各楼层所承担的荷载随上部结构施工不断进行而改变情况。对实 测结果的分析和讨论,发现顶层混凝土浇筑和底层楼板支撑拆除时,临时受力体系内楼层应力变化很大,对结构的 安全性影响显著;临时受力体系中楼层最大应力值随着施工周期和拆模时间的延长而不断减小,对结构安全起有 利作用。

Abstract: Through on-site investig ation, changes of load borne by each floor with the ongoing process of upper parts were studied. Based on analysis and discussion of test results, it was found that changes of stress were significant when top slab concrete was being poured and the support was temporarily remov ed, which greatly impacted structure safety. Under temporary stress system, the longer the construction period and removal period, the smaller them aximum stress, which could improve structure safety.

Key words: reinforced concrete structures, construction period, on-site measurement, structure safety
