| 摘 要： | 变形监测是滑坡、沉降等灾害监测的重要支撑手段。地基合成孔径雷达干涉测量技术可提供远距离、大范围、连续空间覆盖的形变结果,无需接触观测目标,在变形监测方面具有广阔的应用前景。利用地基合成孔径雷达系统对隔河岩大坝进行了变形监测实验,分析了环境因素的变化对监测结果产生的影响,对环境改正方法进行了比较,通过对改正结果的分析选取了相应的环境改正方法,并对大坝整体的监测结果进行了分析。实验结果表明,地基合成孔径雷达技术可获取高精度的大坝表面整体形变信息,有利于后期对大坝进行整体稳定性分析。

| Abstract: | GB-SAR (Ground Based Synthetic Aperture Radar) system could perform all-day, all-weather, non-contact and highly accurate deformation monitoring. In the present research, we employed GB-SAR to monitor the deformation at Geheyan Dam, and analyzed the impact of environmental factors on the monitoring result. Moreover, methods of environment correction were compared. By analyzing the correction results. we selected corresponding correction methods. Results show that the deformation information of the entire dam surface can be reflected accurately with the monitoring data corrected by the environmental correction methods, and these corrected data can be used for analyzing the stability of the dam. |
