Joint InSAR and GNSS to monitor land subsidence in coastal areas

doi:10.13474/j.cnki.11-2246.2021.0180

Abstract

Abstract: The traditional point-based geodetic monitoring technology has limitations for regional surface deformation. Spatial geodesy technology proposed in this paper is used to study the surface deformation of the city. In the study, time-series InSAR and GNSS technology are used to monitor the surface deformation field in the coastline area of Shenzhen and Hong Kong Special Administrative Region of China. At the same time, a time series of three-dimensional changes at the network reference station in the Hong Kong Special Administrative Region is generated. The results show that there is a significant substitution phenomenon in the reclamation area, especially in the subway construction area and the buildings with shallow foundations in the reclamation area.

Key words: time-series InSAR, subsidence, GNSS, coastal urban area
