郑州市地面沉降InSAR监测
|
摘要
针对地面沉降长期作用将会对城市建筑物、防洪排汛系统、地下线性管道,以及地铁、铁路等线性城市基础设施造成破坏,直接威胁人民生活及工业生产安全的问题,该文联合永久散射体雷达干涉测量和短基线雷达干涉测量技术,基于郑州市2012年至2013年的15景TerraSAR-X影像,提取了郑州市地面沉降场,并分析了郑州市地面沉降的原因及时空变化特征。研究区发现了4个沉降较显著的区域,均处于大型地表地下建设以及建筑物密集区,最大沉降量达到-48.66mm。结合研究区地质条件、地表环境以及已有研究成果分析表明,监测出的郑州市沉降区域是合理的。该监测成果同时验证了联合永久散射体干涉测量与短基线干涉测量方法监测城市地面沉降的有效性。
Land subsidence is an irreversible regional geological disaster with slow accumulation,if long-term effects,not only the city buildings,flood control system,linear underground pipelines,linear urban infrastructure such as subway and railway,but also people's life and industrial production,will under threat.The urban subsidence during 2012 to 2013 of Zhengzhou was detected and the reason of subsidence and spatial-temporal evolution of subsidence was investigated through 15 TerraSAR-X images by integrating persistent scatterer interferometry and small-baseline interferometry.The detected deformation shows that there are four significant subsidence regions in Zhengzhou,which are all located in the area with large scale surface or underground construction and intensive buildings,and the maximum subsidence is up to -48.66 mm.The detected subsidence regions are proved to be reasonable through comprehensive analysis of the geological conditions,the surface environment and the existing research results about the study area.The investigation further indicates that the combination of PSI and SBAS can be used to monitor urban subsidence effectively.
