摘要/Abstract

摘要： 收集了2018—2019年度的32景雷达卫星影像,采用PS-InSAR技术对荆江大堤石首至监利段堤防的沉降进行监测,获取了2018年4月至2019年4月间该区段堤防的平均沉降速率,分析了其形变趋势及物理机制。结果表明,该段堤防存在不均匀沉降,但在一年中形变的趋势会随时间变化。利用雷达卫星时序分析技术可实现荆江堤防的沉降情况高效大范围监测,表明该技术在长江堤防形变监测上具有很大的应用潜力。

Abstract: In this research we collected 32 radar satellite images from 2018 to 2019, and monitored the settlement of Jingjiang segment of Yangtze River dyke segment from Shishou to Jianli using PS-InSAR technology. We obtained the deformation trend and its physical mechanism by analyzing the average settlement rate from April 2018 to April 2019. Results unveiled uneven settlement in this segment of dike; but the deformation trend changes with time in a year. Radar satellite time series analysis technology could highly-effectively monitor the settlement of Jingjiang River dyke in a large range, which suggest that radar satellite time series analysis has great application potential in the deformation monitoring of the Yangtze River embankment.

Key words: monitoring of dyke settlement, Sentinel-1A radar satellite imaging, time series analysis, uneven settlement, Jingjiang segment of Yangtze River dyke
