摘　　要：提出一种含缺陷压力管道极限承载能力图像有限元分析方法,采用内压爆破实验进行验证。结果表明:重构模型与真实模型的几何结构参数最大误差不超过2.50%;数值模拟计算所得极限载荷与实验爆破压力的误差分别为0.559%、7.020%、5.710%,且数值计算结果略小于实验结果。An image finite element analysis method for ultimate bearing capacity of the pressure pipe with defects was proposed.The results of internal pressure blasting test show that,the maximum error of the geometric structure parameter between the reconstructed model and the real model is less than 2.50%.The errors of the limit load calculated numerically and the experimental bursting pressure are 0.559%,7.020%and 5.710%respectively,and the numerical calculation results are slightly smaller than the experimental results.
