摘　　要：首先提出碳纤维加固受弯构件承载力计算公式,并提出碳纤维加固材料强度系数,结合收集到的粘贴碳纤维加固梁承载力试验数据,建立碳纤维加固钢筋混凝土梁的抗弯承载力提高系数计算公式,实现粘贴碳纤维加固梁的简化计算。开展了粘贴碳纤维加固预应力高强度混凝土(PHC)管桩抗弯承载力试验。试验结果表明,提出的碳纤维加固梁承载力计算公式也可用于碳纤维加固混凝土管桩承载力的计算。The bearing capacity formula of flexural members strengthened with CFRP and the material strength coefficient are proposed in this paper. Combined with experimental data, we obtained the calculation method to improvement coefficient, which can be used to simply calculate the bearing capacity. The bending capacity test of PHC pipe pile strengthened with CFRP was developed. The test results show that the calculation formula for beams strengthened with CFRP also can be used to calculate the bearing capacity of pipe piles strengthened with CFRP.
