沧榆高速顶管区地质雷达探测分析

Detection and Analysis of GPR in Cangyu Highway Pipe Crossing Areas

在高速公路运营阶段,利用地质雷达探测并分析次生灾害的案例并不多见,尤其是在探测公路顶管穿越区的次生灾害方面。在道路顶管施工中,不可避免出现次生灾害,影响公路的正常运营。为便捷的识别路基以下的次生地质灾害对路网的影响,本研究应用地质雷达技术,以特定的顶管为中心,两侧各15米,分布多条测线,探测道路病害,经过治理后复测,对探测出的病害路段再次治理后探测。

During the operation phase of highways,there are not many cases of using ground penetrating radar to detect and analyze secondary disasters,especially in detecting secondary disasters area where highway top pipes pass through.During road jacking construction,secondary hazards inevitably occur,affecting the routine operation of the highway.In order to conveniently identify the impact of secondary geological hazards below the roadbed on the road network,this study applies GPR technology to detect road diseases by distributing multiple survey lines centered on a specific pipe jacking,15 meters on each side,and after treatment and re-testing,and detecting the detected diseased sections after treatment again.
