摘要

摘要: 目的大同盆地是我国地面沉降、地裂缝等地质灾害集中发育区之一。采用短基线InSAR方法对覆盖该地区的40景 EnvisatSAR数据进行了处理,获取了大同盆地的地面沉降分布特征,分析了典型沉降区的时间序列形变特征,研究了盆地地面沉降、地裂缝及断裂活动之间的相互影响。研究表明,大同市地面沉降受地下水开采影响明显,同时其走向受断裂带控制。此外,还分析了大同机车厂地裂缝的水平及垂直活动特征,及其与降水量的关系。

Abstract: Objective Datong basin is one of the geological hazards development zones where geological disasterhas a high frequency,such as the ground subsidence,ground fissure and so on.In this paper,thesmall baseline subset(SBAS)InSAR technology was used to process 40scenes of Envisat SAR datacovering this area,and the surface deformation distribution characteristics were obtained.The timeseries deformation characteristics of the typical subsidence area were analyzed.The relationship amongthe regional ground subsidence,ground fissures and fault were also analyzed.The results show thatthe ground subsidence is influenced by groundwater exploitation and controlled by the faults.At thesame time,the horizontal and vertical activity characteristics of the Locomotive Factory ground fissurewere analyzed,and its relationship with precipitation.
