摘　　要：通过对九江长江大桥角焊缝实桥取样,作了不同取样方式和不同部位的裂纹扩展速率试验,并做了分析对比,给出了九江长江大桥角焊缝裂纹扩展速率的规律,从而为九江长江大桥寿命估算提供了依据.Experimental study for crack growth rates of fillet welds are carried out with specimens cut from real bridge structures of Jiujiang Yangtze River bridge for different kinds of fillet welds and positioas. The patterns of crack growth rates of fillet welds are then concluded so that the basis for evaluating the bridge life is provided.
