摘要
为更直观、高效地探测土石堤坝渗漏,基于无人机载红外-可见双光成像的渗漏巡查模式,提出了土石堤坝渗漏非接触无损快速巡查方法。综合考虑双光设备成像效果,讨论了该方法无人机航高设定问题,给出了土石堤坝工程渗漏巡查实现流程,并在多种天气条件下开展了实际工程现场巡测试验。试验结果表明:该巡查方法能有效探测土石堤坝坡面渗漏和管涌,且操作简便、作业高效、结果直观、夜间工作性能良好,对大体积、长线状堤坝工程渗漏巡查具有很好的实用性。结合野外巡测试验,指出了该方法应用于实际工程时需充分考虑复杂地面条件、温度变化、成像设备等因素的影响。
By introducing the detection mode of UAV-mounted infrared and visible dual-light imaging,the non-destructive and fast detection technique of earth-rock embankment leakage is proposed for the more intuitive and efficient leakage detection of earth-rock embankments.The altitude setting of a UAV is discussed considering the imaging effect of the dual light equipment.The implementation procedure of using UAV-mounted infrared and visible dual-light imaging to detect the leakage of earth-rock embankment project is proposed,and the site detection tests of actual project are carried out under various weather conditions.The results of the tests reveal that this detection method can effectively discover the slope leakage and piping in the earth-rock embankment,and it is simple,efficient,and intuitive,with good performance at night.This detection method is excellent for the leakage inspection of large-volume and long-linear embankment projects.The limitations of this method in the practical engineering such as being affected by complex ground conditions,temperature changes,and surface sensing are also discussed.
