【摘要】 通过对室内混凝土模型试件进行声波测试和CT成像,研究模型两侧测点数量逐渐减少的情况下生成CT成像图的差异性,并与试验模型进行对比分析。结果表明随着导入CT软件中的测点数量减少,CT成像图中缺陷的大小受到一定的影响,但缺陷位置和陷形状受的不变,进一步说明通过弹性波CT成像能直观地反映混凝土内部的质量分布,通过CT成像对混凝土内部缺陷的检测是可靠的。更多还原

【Abstract】 The differences of CT images under each situation of the gradual decrease imported points,which were measured on both sides of the model,were studied and analyses with the tested model,through the experiments of acoustic test and CT imaging.The results showed that the size of defect in CT images had a certain influence by the number of imported points reduce.But the location and shape of defect had a consistent with the actual.It was further proved that elastic wave CT could visualize reflect the distribution of concrete,and defect detection of concrete through the CT imaging was reliable.更多还原
