地质雷达技术在既有铁路挡墙质量检测评价中的应用

Application of GPR to Quality Inspection of Retaining Wall of Existing Railway

介绍了地质雷达技术检测挡土墙质量的原理,以及在检测评价既有铁路挡土墙中的应用,实测资料表明能够较好地反映墙体厚度和砌筑质量,查清存在质量缺陷的挡墙范围和位置,对存在缺陷的挡墙的危险状态作出评价,既而为铁路工务部门消除隐患,确保铁路安全运营具有重要意义。

The theory of quality inspection of retaining wall is introduced,and the application of evaluating the railway retaining wall is also mentioned. The actual data could reflect the thickness and quality of the retaining walls,and check the range and position of the walls that exist quality bug,then the evaluation could be made and thereby the railway department could eliminate hidden trouble ,and be sure that the railway can be safe.
