【摘要】：地面沉降灾害制约了社会经济可持续发展,目前地面沉降监测广泛采取水准测量、GPS测量和InSAR技术等方法。为有效解决不同技术方法在精度、时间分辨率和空间分辨率上的缺陷,综合其优点,本文提出了对InSAR、水准及GPS数据进行精密处理和高效融合的理论方法,获取高精度、高时空分辨率的地面沉降监测成果。以广州南沙试验区数据实例验证了理论方法的可行性和可靠性。
[Abstract]:Land subsidence disaster restricts the sustainable development of social economy. At present, leveling GPS and InSAR are widely used in land subsidence monitoring. In order to solve the shortcomings of different technical methods in precision, time resolution and spatial resolution, and to synthesize their advantages, this paper presents a theoretical method for precision processing and efficient fusion of InSAR, leveling and GPS data, which can obtain high accuracy. Results of land subsidence monitoring with high spatial and temporal resolution. The feasibility and reliability of the theoretical method are verified by an example of Nansha test area in Guangzhou.
