摘要：

针对混凝土基桩超声波层析成像技术中两声测管间剖面区域的竖向尺寸远大于水平尺寸、换能器布置间距相对稀疏的测试特征，提出基于换能器布置尺寸加密的场源点分布形式、发-收端互换虚拟射线组、考虑完整场修正的改进SIRT算法及层析成像后处理技术等优化方法，对基桩超声波层析成像效果进行提升. 利用有限元分析软件ABAQUS，对不同工况条件下的超声波层析成像发射、接收换能器信号进行数值模拟，分析影响成像效果的工况参数. 研究结果表明，采用优化后的层析成像反演算法可以更加快速、准确地定位以及量化声测管间剖面区域内的潜在质量缺陷，具有较高的计算可靠性.

Abstract:

The field source-point encryption technique based on the layout of the transducers, the scheme of reverse virtual ray path pair of omitting-receiving transducers, the improved SIRT algorithm considering the whole field correction, and the computed tomographic image post-processing technology, etc., were proposed respectively to improve the ultrasonic tomography effect of the RC pile foundations in view of the test characteristics of reinforced concrete (RC) pile foundation that the vertical dimension of cross-section area between two acoustic tubes is significantly larger than that of the horizontal dimension and the transducer spacing is relatively sparse. The ultrasonic tomography omitting and receiving transducer signals under different working conditions were simulated by using the finite element analysis software ABAQUS. Condition parameters that affect imaging effects were analyzed. Results show that it is quicker and more accurate to locate and quantify the potential defect among the cross-section area between two acoustic tubes by employing the proposed algorithms. The calculation reliability of the algorithm is high.
