| 摘 要： | 利用2016年8月—2017年8月的14景Sentinel-1雷达影像，采用小基线集（SBAS）技术，提取了鲁西南地区地面沉降信息，并结合公路和铁路等专题数据开展了沉降影响分析。研究结果表明：鲁西南地区地面沉降严重且覆盖范围较大，最大沉降漏斗位于郓城县主城区，沉降速率达-134.06 mm/a；同时地面沉降对铁路有一定影响，特别对公路影响较大；并与水准测量数据进行对比，验证了SBAS用于沉降监测的准确性和时效性。

| Abstract: | In this paper, we use the Sentinel-1 radar image of 14 scenes from August 2016 to August 2017, and use the small baseline set (SBAS) technique to extract ground subsidence information in the southwest of Shandong Province. Combined with special data such as roads and railways, settlement impact analysis is carried out. The results show that the ground subsidence is serious and covers a large area in the southwest of Shandong Province. The largest settlement funnel is located in the main urban area of Yancheng County, with a settlement rate of -134.06 mm/a. At the same time, ground subsidence has a certain impact on the railway, especially the larger impact on the highway. We compare with level data to verify the accuracy and timeliness of SBAS technology for settlement monitoring. |
