摘　　要：大规模的煤炭开采引起矿区地面沉陷,而同时随着地铁交通的发展,矿区沉降作为地铁建设中的不良工程地质问题也越来越突出.在矿产资源开发十分广泛的省份,地铁选线时经常无法回避沉降区的影响.因此依据矿区历史沉降趋势来选择地铁线路,对我国地铁交通的发展具有深远的意义.小基线子集法能克服传统合成孔径雷达差分干涉测量技术的一些弊端,并对影像数量要求不太严格,具有传统监测方法无法比拟的优势.本文以淮南谢家集矿区为研究区域,以ALOS-Palsar数据为数据源,采用SBAS技术对地铁线拟穿过矿区进行遥感监测.最终获取研究区域监测时间段内累积沉降量及年平均沉降速率,所得结果与现场调查结果基本一致.对不同线路方案通过该沉陷区的可行性进行分析,从而为地铁线路方案选择提供技术支撑,并验证了SBAS方法监测矿区地表形变的可行性.The large-scale coal mining causes the ground subsidence,Meanwhile subway traffic develops fast in country.The problem of ground subsidence as the bad geological engineering matters encountered during the subway construction is becoming more and more prominent.The subway route selection could not avoid the impact of ground subsidence in some provinces which mineral resources was abroad exploitation.So choose the right line based on the history deformation tendency is of great significance to the development of subway traffic.Small Baseline Subset(SBAS)can overcome the abuses of traditional Differential Synthetic Aperture Radar interferometry(D-InSAR),and it is not strict with quantity of images.So it has distinct advantages over the traditional monitor methods.This paper taking huai nan xie jia ji mining area as the study area,with the ALOS-Palsar images as data sources,and the SBAS method is adopted for the subway ground settlement monitoring.Eventually get the average of settlement rate and accumulative land subsidence.It is found that the deformation tendency are consistent with on-site investigation results.Some feasibility study on the different subway route selections was did when subway passing through mine.So that It provide technical support for the choice of subway route,and proven technology's feasibility of the SBAS to monitor mine ground subsidence.
