摘要
为研究东营市发生地面沉降的空间分布规律,在东营市市域范围内建立GPS监测网,通过GPS精密数据处理获得了精度优于4mm的大地高,经三年观测结果统计可初步判断东营市地面沉降变化总体表现为自北向南,自西向东沉降量逐渐增大,且诱发东营市地面沉降的主导因素为地下水开采。
In order to study the ground settlement in Dongying area,we set up the GPS monitoring net.By means of the precise GPS data processing,we get the geodetic heights,and the precision is less than4 mm. From the results of three years observations,we can arrive at a conclusion that the ground settlement is increasing from north to south and from west to east,and the main reason of ground settlement is mining of groundwater.
