摘　　要：为研究碳纤维复合材料(CFRP)对修复的点蚀加筋板极限强度的影响,通过对CFRP修复裂纹钢板的试验进行数值模拟与试验结果比较,验证了数值模拟方法的可行性。考虑加筋板的受载特性,分别以单轴压缩、双轴压缩、侧向载荷以及联合载荷(双轴压缩、侧向载荷)对CFRP修复后的点蚀加筋板的极限承载能力进行研究。结果表明,采用CFRP修复方法可有效提高点蚀加筋板的极限强度。In order to study repair effect of carbon fiber composites on the ultimate strength of pitting reinforcement plates,feasibility of the numerical simulation method is firstly verified by comparing the numerical simulation with the test results of repairing cracked steel plates with carbon fiber composite.Considering loading characteristics of the reinforced plate unit,ultimate load carrying capacity of the CFRP-repaired pitting reinforced plate was investigated by uniaxial compression,biaxial compression,lateral load and combined load(biaxial compression,lateral load)respectively.The results show that ultimate strength of the repaired pitting reinforced plate can be effectively improved.
