| 摘 要： | 滑坡是仅次于地震的发生最频繁、造成损失最严重的地质灾害之一，给人民群众生命和财产安全带来了巨大威胁。为了能够对危险滑坡进行动态监测，采用GPRI-Ⅱ地基雷达系统，研究了滑坡形变时序分析关键技术，制定了地基雷达数据时序处理流程，并应用于浙江绍兴某道路边坡稳定性监测。实验结果表明，该边坡存在1处明显的形变区域，位于施工现场堆积区，最大形变量达到3.5 mm/d。目前在观测条件满足的情况下，地基雷达可以达到亚毫米级的形变监测能力，已经成为灾害预警和治理的重要手段之一。

| Abstract: | Landslide is the second only to earthquake as one of the most serious geological hazards, which occur most frequently and cause the most serious losses. It poses a great threat to people's lives and property safety. In order to monitor dangerous landslides dynamically, GPRI-Ⅱ ground-based radar system is used in this experiment to study the key technology of landslide deformation time series analysis, and the main process of ground-based radar data time series processing is formulated. It is applied to the stability monitoring of a road slope in Shaoxing, Zhejiang Province. The experimental results show that there is an obvious deformation area in the slope, which is located in the accumulation area of the construction site, and the maximum deformation is 3.5 mm/d. At present, ground-based radar has the ability to monitor deformation with sub-millimeter accuracy when the observation conditions are satisfied. Ground-based radar has become one of the important means of disaster early warning and control. |
