This algorithm can overcome the limitations of 3D tomography technology and traditional sonic logging techniques for piles testing and the shortcomings. By optimizing the distribution of spatial field source points, the Dijkstra algorithm is used to accurately track the elastic wave propagation path in three-dimensional space. And combined with the improved SIRT algorithm, the visualization of the internal structure of concrete foundation piles and the rapid location and quantitative assessment of potential defects are achieved. Subsequently, numerical simulation verification was carried out through the finite element analysis software ABAQUS. The impact of key technical parameters including transducer arrangement density, field source point encryption coefficient and defect characteristics on the three-dimensional tomography results was analyzed. Finally, the proposed optimization algorithm was applied to a bridge pile foundation on the Qiantang River in Hangzhou City, Zhejiang Province. The results demonstrate that the technology can accurately locate concrete defects and provide references for defect types and severity, offering theoretical and technical support for innovations in sonic logging methods for piles testing., correspAuthors=null, authorNote=null, correspAuthorsNote=null, copyrightStatement=null, copyrightOwner=null, extLink=null, articleAbsUrl=null, sourceXml=null, magXml=null, pdfUrl=null, pdf=null, pdfFileSize=null, pdfExtLink=null, richHtmlUrl=null, mobilePdfUrl=null, reviewReport=null, pdfFirstPage=null, abstractGraph=null, abstractGraphContent=null, abstractVideo=null, citation=null, cebUrl=null, magXmlContent=null, mapNumber=null, authorCompany=null, fund=null, authors=null, authorsList=null), CN=ArticleExt(id=1259474418775016057, articleId=1259474417512530551, tenantId=1146029695717560320, journalId=1259198796492718097, language=CN, title=基于三维空间路径追踪的混凝土基桩层析成像技术研究, columnId=1259474416170295982, journalTitle=土木工程学报, columnName=桥梁工程, runingTitle=null, highlight=null, articleAbstract=该文针对传统基桩声波透射法检测的局限以及三维层析成像技术的不足，提出一种基于三维空间路径追踪的基桩超声波层析成像优化算法。通过优化空间场源点分布，利用Dijkstra算法在三维空间内精确追踪弹性波传播路径，并结合改进SIRT算法，实现对混凝土基桩内部结构的可视化以及潜在缺陷的快速定位与量化评估。随后，通过有限元分析软件ABAQUS开展数值模拟验证，并分析关键技术参数包括换能器布置密度、场源点加密系数及缺陷特征等对三维层析成像结果的影响。最后，将所提出优化算法应用于浙江省杭州市钱塘江某大桥桩基础实际工程测试案例，结果表明该技术能够准确定位混凝土缺陷位置并提供缺陷类型及程度参考，有望为基桩超声波透射法检测技术创新提供理论基础和技术支持。, correspAuthors=吴君涛, authorNote=叶启扬(2000—)，男，硕士研究生。主要从事桩基动力理论及测试技术开发研究。
