摘　　要：地基边坡雷达系统能以毫米级精度测量边坡、山体、桥梁、大坝和高楼等大型建(构)筑物的位置变化,是星载InSAR和常规大地测量手段的有效补充。为探究MSR地基边坡雷达在边坡监测中的适用性,介绍了该系统的工作原理、软硬件系统组成、技术参数及其独特优势,并结合北京延庆冬奥赛区3处危险边坡稳定性监测实例进行分析。结果表明:3处边坡均存在明显的形变区域。在满足观测条件的情况下,地基雷达可以达到亚毫米级的形变监测能力,可为安全生产提供有力的技术保障。该方法对边坡变形监测具有重要的参考价值,已经成为灾害预警重要手段之一。The ground-based slope radar system can measure the position changes of large buildings such as slopes,mountains,bridges,dams and high buildings with millimeter-level accuracy,which is an effective supplement to spaceborne InSAR and conventional geodetic methods.In order to explore the applicability of MSR ground slope radar in slope monitoring,the working principle,hardware and software system composition,technical parameters and unique advantages of the system are introduced,and the stability monitoring of three dangerous slopes in Beijing Yanqing Winter Olympics is analyzed.The results show that the three slopes have obvious deformation regions.Under the condition of meeting the observation conditions,the ground-based radar can achieve the deformation monitoring capability of sub-millimeter level,which can provide strong technical support for safe production.This method has important reference value for slope deformation monitoring and has become one of the important means of disaster early warning.
