摘　　要：地表沉降是影响引黄济青工程安全与稳定运行的一项重要因素。为获取引黄济青工程沿线的地表沉降状况,分别采用SBAS-InSAR与DS-InSAR技术对引黄济青工程沿线进行了地表形变监测。SBAS-InSAR结果与DS-InSAR结果间的相关系数为0.736,验证了结果的可靠性。处理结果表明,引黄济青渠道线北段存在较为明显的沉降现象,南段则相对稳定。最后,对引黄济青工程线路末端的棘洪滩水库进行了长时序的InSAR形变监测,发现三处形变相对明显的区域。形变监测结果为后续引黄济青工程线路设施的维护提供了参考。The surface deformation monitoring project of the Yellow River to Qingdao Reconstruction and Expansion Project in Shandong Province is studied in depth.Synthetic aperture radar interferometry(InSAR)technology was used to continuously monitor the project for 1 year and 9 months.Through SBAS-InSAR and PS-InSAR techniques,high-precision surface deformation data were successfully obtained and compared with leveling data.The result show that the overall stability of the reconstruction and expansion project of the Yellow River to Qinghai is stable,and there is a slow settlement phenomenon in the local area.The application prospect of InSAR technology was discussed in surface deformation monitoring,and puts forward the prospect of future work.
