  • 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.
