摘　　要：对5块相同配筋的CFRP加固的RC双向板和1块对比板进行了试验研究,试验中考虑了贴布量、贴布方式、二次受力等变化因素,分析各种贴布方式下加固板的裂缝开展情况,为设计、施工及工程加固应用提供了有价值的参考依据。Experimental research on 5 RC two-way slabs reinforced with CFRP and 1 RC slab was carried out in this paper.In the test,many fac-tors were considered,such as the quantity of CFRP,method of strengthening,secondarily loading.Crack methods of the strengthened slabs wereanalyzed and the conclusion that be proposed from the test can be used for reference in design and construction of reinforcement structures.
