摘　　要：在模拟不同现役混凝土棱柱体柱情形下,测得CFRP约束预压混凝土棱柱体试件的应力-应变曲线,并对其进行分析;与此同时还得到未约束混凝土试件、CFRP约束混凝土试件两类对比试件的应力-应变曲线,并将后者与前者进行对比分析,为实际工程加固提供试验依据。In simulated different concrete prism column in work,stress-strain curves were obtained and analyzed of CFRP restrained concrete in work prism specimen with different axial compression ratio.We also got the curves of nonrestrained and CFRP restrained specimen both of which are compared in order to provide the experimental basis for the actual engineering reinforcement.

关 键 词：CFRP 棱柱体试件 现役混凝土 轴压比 应力-应变关系
