摘　　要：边坡变形监测是防止滑坡、崩塌、泥石流等地质灾害的有效途径之一。圆弧式地基合成孔径雷达是一种非接触式的新型地表形变监测设备,具有高分辨率、高频率、高精度、全方位、全天候实时监测等优点,更能有效地满足边坡变形监测的全面性和连续性要求。为了验证该设备在边坡变形监测中的效果和精度,本文采用两种便携圆弧式地基合成孔径雷达系统进行测试。测试结果表明,两种设备均能快速、全面地获得整个边坡的形变情况,具有较高的分辨率和亚毫米级的监测精度,且能实时发出预警,是一种全面高效的边坡变形监测手段。Slope deformation monitoring is an effective way to prevent landslides,collapse,debris flow,and other geological disasters.Arc ground-based synthetic aperture radar(GB-SAR)is a new type of non-contact surface deformation monitoring equipment,which has the advantages of high resolution,high frequency,high precision,all-round and allweather real-time monitoring.It can effectively meet the comprehensive and continuous requirements of slope deformation monitoring.To verify the effect and accuracy of this equipment in slope deformation monitoring,two portable arc GB-SAR systems were employed for testing.The test results show that both devices can quickly and comprehensively obtain the deformation of the entire slope,which have high resolution and sub-millimeter monitoring accuracy.They can issue realtime early warning,which are comprehensive and efficient slope deformation monitoring methods.
