摘要
为了更好地了解首都国际机场区域差异性沉降的原因,该文基于小基线集干涉测量理论对2015年7月至2019年9月的60景Sentinel-1A降轨数据进行技术处理,获取了首都机场地区高精度地表形变探测结果,并对其时空演化进行分析。结果表明,首都机场地区地表出现分区性差异沉降现象,观测时段内累积沉降量差异超287 mm,可能影响机场的安全运行。发现地下水漏斗时空分布演化与机场区域差异性沉降响应特征较弱,由顺义—良乡断裂构造发育的顺义地裂缝是造成机场差异性沉降发展的主要原因。
In order to better understand the reasons for the regional differential settlement of the Capital International Airport,this article used the small baseline set interferometry theory to perform technical processing on the 60 scenes of Sentinel-1 A de-orbit data from July 2015 to September 2019,and obtained the capital High-precision surface deformation detection results in the airport area,and analysed of its temporal and spatial evolution.The results showed that there were zonal differential settlements on the surface of the Capital Airport area,and the cumulative settlement difference during the observation period exceeded 287 mm,which might affect the safe operation of the airport.It was found that the temporal and spatial evolution of the groundwater funnel and the response characteristics of the differential settlement of the airport area were weak.The Shunyi ground fissure developed by the Shunyi-Liangxiang fault structure was the main reason for the development of differential settlement of the airport.
