    GPS测量技术在锡山市地面沉降研究中的应用

    APPLICATION OF GPS OBSERVATION TECHNIQUE TO STUDY OF GROUND SUBSIDENCE IN XISHAN CITY

    • 摘要: 通常研究认为, 苏锡常地区超量开采地下水是产生地面沉降最主要的因素之一。锡山市地下水开采十分强烈, 其地面沉降灾害也最为严重。为了有效地分析研究地面沉降的发生发展过程, 必须获取一定时间间隔内的地面沉降实测值, 全球定位系统 (GPS)就是一种既经济又高效的测量手段。本文在简要介绍了锡山市地质、水文地质及地下水开发利用情况的基础上, 重点阐述了运用GPS测量技术对锡山市地面沉降进行首次实测的情况, 并对其测量结果进行了系统分析, 最后对锡山市地面沉降的发展历史和现状进行了初步讨论。

       

      Abstract: The study suggests that one of the most important factors causing ground subsidence is the over-pumping groundwater in the Suzhou-Xishan-Changzhou region. Water pumping in Xishan City is most intense and hence damage from the ground subsidence is also most heavy. In order to effectively analysis and study of the process of occurence and development of ground subsidence, it is necessary to obtain observation data of ground subsidence for a certain long time. Global positioning system(GPS) is an ecnomic and high-effective approach. After a brief account of geology, hydrogeology and development and utilizatoin of groundwater in the Xishan city in the paper, a stress is put on the first observation of ground subsidence in the city by using GPS technique and the obtained data are systematically analyzed. Finally, the development history and current status of the ground subsidence in the city are preliminarily discussed.
