普适性北斗用于城市地面沉降实时监测研究
Universal application of BeiDou for real-time monitoring of urban ground subsidence research
摘要
Abstract
In the context of rapid urbanization today,issues such as land subsidence have a significant impact on the stable operation of cities and the lives of residents.Strengthening the monitoring of land subsidence can effectively promote the implementation of prevention and control measures,and reduce related economic losses.With the continuous development of China's BeiDou navigation satellite system(BDS),this system plays an important role in various fields in our country.This paper,combining universal BeiDou receivers and the high-precision positioning software GAMIT/GLOBK,has designed a real-time monitoring network for urban ground subsidence.Taking Xi'an as the experimental area,a real-time urban ground subsidence monitoring network was established.The results show that the BDS system can achieve a monitoring accuracy of 3 mm in the horizontal direction and 10 mm in the elevation direction.Compared with the monitoring results of the GPS,the differences in the east,north,and elevation directions of the BDS system are all lower than 3 mm.The experiment proves that the universal BeiDou fully utilizes its positioning accuracy and real-time characteristics in urban ground subsidence monitoring,which helps enhance the city's risk response capability,achieving safer,more stable,and sustainable urban development.关键词
