【摘要】 采用疏浚土充填袋筑堤是一种新型技术,尚处于开发研究阶段,相应的检测手段等很不完善。基于GPR(地质雷达)的高效、无损、分辨率高等特点,开展GPR探测堤体结构特性的试验研究,并通过标定及与传统监测手段的比对等方法来论证探测堤体结构特性的可行性。研究成果表明,采用地质雷达探测充填袋压坡体结构其结果与分层沉降等实测资料较为吻合。充填袋典型的雷达图像特征,为充填袋筑堤变形的快速检测提供了依据。更多还原

【Abstract】 The application of dredged soil filling bags in diking is a new technique which is still at the R&D stage.Therefore,its corresponding detection method has not yet been fully developed.As GPR(Ground Penetrating Radar)have the advantages of high efficiency,no destruction,high resolution and so on,it was adopted to detect the characteristics of the dam body structure.Furthermore its feasibility in doing so was demonstrated by calibration of the radar and the comparison between this method and other conventional monitoring methods.The study indicates that GPR detection results are consistent with the monitored data of layered settlement.The typical image data of the detection provides the theoretical basis for fast deformation detection of dams built with filling bags.更多还原
