摘要
城市建筑物是城市化建设主要组成部分,建筑物安全是城市建设与发展的重要前提之一.利用哨兵一号(Sentinel-1A)数据(时间覆盖为360 d),基于短基线集干涉技术(SBAS-InSAR),在分析其技术原理及工作流程的基础上,对乌鲁木齐市城区及周边地区进行了地面沉降监测实验,并对监测结果进行统计,结合地面基础资料分析了其沉降原因,实验结果表明:沉降区域多为建筑兴建、资源开采活动频繁的地区,并主要分布在米东区、水磨沟区和沙依巴克区西山附近,其中米东区和水磨沟区最为严重,沉降速率最高可达97 mm/a.
Urban buildings are the main component of urbanization. Building safety is one of the important prerequisites for urban construction and development. Based on the short baseline interferometric technique （SBAS InSAR）, Sentinel 1A dataset, covering the Urumqi city and with a time span of 360 days, is used to research the subsidence of Urumqi city and surrounding areas, statistical analysis for the reason, and to explore the technical principles and data processing workflow. Through experiments, the subsidence areas have been found mostly locating where buildings are built and nature resources are extracted frequently. They are mainly distributed in the area of Midong, Shuimogou and Shayibake. Among them, the more serious ones are Midong and Shuimogou area, with a high sedimentation rate up to 97 mm/a.
