地形微变远程监测仪在地表微变形监测中的应用

Application of IBIS-L system in micro-deformation monitoring of ground surface

边坡监测是工程中经常面对的问题。常规的外观监测方法主要有全站仪法、GPS法等,这些方法是点源监测,监测频率低、工作量大。介绍了采用地形微变远程监测仪(IBIS-L)对滑坡、煤矿进行边坡外部变形监测的方法。该设备结合了步进频率连续波技术和合成孔径雷达技术。实例监测结果表明,地形微变远程监测仪在地表微变监测方面具有很高的先进性,可以24 h进行面源观测,测量精度高、范围广、操作方便;数据采集过程无需人工干预,简化了监测过程,有效降低了工作强度。

Landslide monitoring is a common problem in the engineering. The routine methods of landslide monitoring such as electronic total station and global positioning system （GPS） belong to point - to - point monitoring with low efficiency and low monitoring frequency. The external deformation of landslide and a slope of coal mine are monitored with the IBIS - L （ Image by Interferometric Survey - L） system. The IBIS - L system is the equipment that integrates the technology of stepped - frequency continuous - wave and synthetic aperture radar. The monitoring results indicate that, the IBIS - L system for micro - deformation monitoring of ground surface has great advantages of continuous monitoring with high accuracy, large coverage of survey area and easy to operate.
