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

    • 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.
