摘　　要：以某6层框架结构为例,因4层某楼板负弯矩筋钢筋保护层超出允许偏差较大,为保证结构工程的安全使用,考虑荷载最不利因素,采用分级加载方式,在楼板原位进行了安全性静载检验,测量混凝土现浇板的荷载、挠度、残余应变等指标,与理论形成对比,并对试验结果与理论结果进行讨论和分析,为后续类似工程提供参考。Taking a six story frame structure as an example,in order to ensure the safe use of the structural engineering,considering the most unfavorable factors of the load,this paper adopts the method of graded loading to carry out the safety static load test in the original position of the floor,and measures the load,deflection,residual strain and other indicators of the cast-in-place concrete slab,and the theory In order to provide reference for similar projects in the future,it is necessary to discuss and analyze the test results and theoretical results.
