【摘要】：地面沉降災(zāi)害制約了社會經(jīng)濟(jì)可持續(xù)發(fā)展,目前地面沉降監(jiān)測廣泛采取水準(zhǔn)測量、GPS測量和InSAR技術(shù)等方法。為有效解決不同技術(shù)方法在精度、時(shí)間分辨率和空間分辨率上的缺陷,綜合其優(yōu)點(diǎn),本文提出了對InSAR、水準(zhǔn)及GPS數(shù)據(jù)進(jìn)行精密處理和高效融合的理論方法,獲取高精度、高時(shí)空分辨率的地面沉降監(jiān)測成果。以廣州南沙試驗(yàn)區(qū)數(shù)據(jù)實(shí)例驗(yàn)證了理論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.
