基于超声CT成像的钢-混凝土组合结构界面损伤识别研究

针对传统超声检测方法难以准确识别钢-混凝土组合结构内部缺陷的难题,提出了基于超声Computed Tomography (CT) 成像的钢-混凝土组合结构界面剥离损伤量化方法。研发了具有电磁屏蔽功能的磁吸式新型超声换能器,利用Akaike Information Criterion (AIC) 算法提取透射波初至的方法。基于所建立的正演数值模型和反演分析,系统性研究了Back Projection Technique (BPT),Algebra Reconstruction Technique (ART),Simultaneous Iterative Reconstruction Techni...
