摘要。早期发现滑坡对灾害预防具有重要意义，而传统的测量方法仍然是一项非常困难的工作。干涉合成孔径雷达（InSAR）技术为我们提供了覆盖范围广、精度高的沿坡位移监测能力。在本文中，我们提出了一种定性的多基线DInSAR方法来早期发现和绘制潜在的滑坡。选取317国道和213国道两段作为研究区域。利用该方法，对10个滑坡潜在区进行了快速有效的早期探测和测绘。其中，石大关滑坡于2017年8月发生垮塌，与我们的研究结果相吻合，表明该方法可以成为获取滑坡早期探测图的有效途径，以辅助未来的防灾工作。
Abstract. Early detection of landslides is important for disaster prevention, which was still very hard work with traditional surveying methods. Interferometric Synthetic Aperture Radar (InSAR) technology provided us the ability to monitor displacements along the slope with wide coverage and high accuracy. In this paper, we proposed a qualitatively multi-baseline DInSAR method to early detect and map the potential landslides. Two sections of China National Highway 317 and 213 were selected as study area. With this method 10 potential landslide areas were early detected and mapped in a quick and effective way. One of them (i.e. Shidaguan landslide) collapsed on August 2017, which was coincident with our results, suggesting that this method could become an effective way to acquire the landslide early detection map to assist the future disaster prevention work.
