| 摘 要： | 地面变形对工程建设安全稳定具有一定影响，对工程建设规划、地质灾害防治等具有重要意义。本文利用卫星导航定位基准站（CORS）网全球卫星导航系统（GNSS）连续观测，实现了区域地面大地高、地面重力和地倾斜变化面的监测，通过与部分地质灾害信息进行时空分析，确定了用于地面稳定性变化分析的要素和权重，进而定量分析了地面稳定性变化。该方法在浙江省东南部地区进行了测试验证，获得了较好的效果。利用CORS网连续观测能够定量监测地面变形整个面的变化，分析区域地面稳定性变化情况，可为区域规划和地质灾害防治提供技术支持和参考。

| Abstract: | Ground deformation has a certain impact on the safety and stability of engineering construction,and is of great significance to engineering construction planning and geological disaster prevention.This paper uses the continuous observation of the Global Navigation Satellite System(GNSS)of Continual Operating Reference Station(CORS)network to realize the monitoring of regional ground height,ground gravity and ground tilt changes.Through the time and space analysis with part of the geological disaster information,it is determined the factors and weights used in the analysis of ground stability changes,and then quantitative analysis of ground stability changes.This method has been tested and verified in the southeast region of Zhejiang province,and good results have been obtained.Continuous observation using the CORS network can quantitatively monitor the changes of the entire surface of ground deformation,analyze changes in regional ground stability,and can provide technical support and reference for regional planning and geological disaster prevention. |
