摘　　要：对采用CFRP加固后双向板的承载力进行分析,得出加固后板的承载能力有极大的提高,随着碳纤维布用量的增加,承载力有增加趋势但并不是线性增长;依据塑性铰线理论提出CFRP加固后板的承载力计算模型,并与实际承载力对比得出,该计算模型计算出的加固板承载力值较为保守,偏于安全.The bearing capacity of the two-way reinforced concrete slabs strengthened with CFRP（carbon fiber reinforced polymer） sheets was analyzed. It was then concluded that the bearing capacity of the rein- forced plate after had greatly improved. With the increase of the use of CFRP, the bearing capacity increased but didn＇t show linear growth. Based on the plastic hinge line theory, the calculation model of the bearing capacity of the slabs strengthened by CFRP was put forward. Compared with the actual bearing capacity, the bearing capacity value calculated by this calculation model was comparatively conservative and safer.
