基于3DGIS和超声波层析成像的混凝土基桩可视化信息集成研究
Research on visualized information integration of concrete piles using 3DGIS and ultrasonic tomographic imaging
摘要
Abstract
To address the limitations of traditional cross-hole sonic logging method in defect identification,spatial localization,quantitative analysis,and site information integration,a visualization information integration method for concrete piles that integrates 3DGIS(three-dimensional geographic information system)and ultrasonic tomographic imaging was proposed.Based on an optimized forward and inverse algorithm for multi-transducer arrangement and post-processing techniques,accurate localization,shape reconstruction,and quantitative analysis of internal structural defects in concrete piles were achieved by this method.A three-dimensional information model system was constructed,integrating functions such as 3D structural visualization,data display and query,and risk prediction.Spatial correlation information between pile structures and the surrounding geological environment was effectively integrated.A comprehensive and intuitive basis for safety assessment was provided for engineering personnel.The results show that the proposed method significantly improves pile defect detection accuracy,enhances interpretability of the results,and increases information management efficiency.It is expected to offer a technical pathway and theoretical support for intelligent inspection and safe operation of concrete piles.关键词
