Rapid roadbed disease detection method
The invention discloses a rapid roadbed disease detection method. The rapid roadbed disease detection method comprises the steps of arranging a plurality of displacement monitoring points in an area where road settlement is most obvious, and adopting geological radars loaded with different dominant frequency shielding antennas to detect the displacement monitoring points one by one on a measuringline parallel to the road direction; comparing and analyzing the detection results of the radars with the same measuring line and different dominant frequencies, circling an electromagnetic anomaly region with strong amplitude and a certain extension scale or approximate hyperbolic shape in the transverse and longitudinal directions of an event, and marking electromagnetic anomaly on a measuring line plane layout diagram; and evaluating the void and cavity development conditions of a roadbed and an underlying soil body according to a radar analysis result, determining geological grouting rangeand grouting depth based on the void and cavity development conditions, and continuing to monitor the settlement conditions of road observation points after grouting is completed. According to the method, electromagnetic information within the depth range of dozens of centimeters to several meters below the pavement can be reflected at the same time, the electromagnetic anomaly interpretation precision is high, guidance can be provided for subsequent road grouting construction, and meanwhile the method can be used for evaluating the grouting effect.
本发明公开了一种路基病害快速探测方法。本发明在道路沉降最明显的区域布置若干位移监测点，采用装载不同主频屏蔽天线的地质雷达在平行道路方向的测线上逐一探测；将相同测线不同主频雷达探测结果对比分析，圈出振幅强且同相轴横纵向具备一定延伸规模或近似双曲线形状的电磁异常区域，将电磁异常标注于测线平面布置图上；根据雷达分析成果评价路基及下伏土体的脱空、空洞发育情况，并以此为依据确定地质灌浆的范围及灌浆深度，灌浆完毕后继续监测道路观测点的沉降情况。本发明可同时反映路面以下十几公分至几米深度范围内的电磁信息，电磁异常解译精度高，可为后续道路灌浆施工提供指导，同时可用于灌浆效果的评价。
