The Application of Three-dimensional Ground Penetrating Radar Technology in the Detection of Subsidence Causes and Evaluation of Remediation Effects

介绍采用三维探地雷达探测沉陷脱空的技术特征、设备和工作原理,详细描述某路段沥青道路存在沉陷脱空的基本情况以及利用三维探地雷达进行无损检测的过程。通过处治前的检测结果,确定脱空程度、位置,并计算沉陷的位置、面积和高程差。通过对比两个具有不同沉陷脱空形成原因的路段,分析沉陷、脱空的形成原因,提出针对性的处治措施。根据处治后的检测结果,对注浆、加铺等病害处治措施的处治效果进行评价。研究结果表明,三维探地雷达系统能够准确地探测沥青路面内部的沉陷脱空病害程度、位置和形成原因。基于探测结果,提出具有针对性的处治措施,并评价处治效果的可行性和有效性。

The technical characteristics,equipment,and working principle of using 3D ground penetrating radar to detect subsidence and clearance are introduced.A detailed description of the subsidence and clearance situation in a specific section of an asphalt road,as well as the process of conducting non-destructive detection using 3D ground penetrating radar are conducted.The detection results before treatment are utilized to determine the degree and position of the void,and to calculate the position,area,and elevation difference of the subsidence.By comparing two sections with different causes of subsidence and clearance,the causes of subsidence and clearance are analyzed,and corresponding treatment measures are proposed.The test results after treatment are used to evaluate the effectiveness of treatment measures such as grouting and paving.The findings demonstrate that the 3D ground-penetrating radar system can accurately detect the extent,location,and causes of subsidence and clearance in asphalt pavement.Based on the detection results,targeted treatment measures are put forward,and their feasibility and effectiveness in achieving the desired treatment outcomes are evaluated.
