摘要(Abstract)：

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。
