摘　　要：通过对4块170mm厚预应力混凝土空心叠合板和8块120mm厚预应力混凝土空心底板进行结构性能试验研究及对比分析,研究预应力混凝土空心叠合板的抗裂性及裂缝发展规律、挠度、承载力等结构性能,分析跨高比、配筋率等影响预应力混凝土空心叠合板破坏性质的主要因素。结果表明:与全预应力构件相比,叠合板的抗裂承载力不会因为现浇叠合层而下降。Through structural performance experimental study and contrastive analysis of 4 single supported prestressed-concrete laminated hollow slabs（170 mm） and 8 single supported prestressed concrete hollow soleplate（120 mm）,it was researched anti-cracking,crack development regularity,the amount of deflection and load bearing capacity of prestressed-concrete laminated hollow slabs.It was shown by the analysis that span-depth ratio and steel ratio were the main factors influencing the failure property of prestressed-concrete laminated hollow slabs,it was analyzed and validated anti-cracking capacity could not be reduced because of taminated.
