基于InSAR技术的江苏沿海地区水闸垂直变形风险预警研究
Research on early warning of sluice vertical displacement risk in Jiangsu coastal area based on InSAR technology
摘要
Abstract
Under the influence of complex meteorological,hydrological and geological conditions,the settlement deformation of sluices in coastal area may be excessive,which will affect their operation safeties.Therefore,a three-level early warning system of sluice settlement deformation based on PS-InSAR technology was constructed in this paper.Based on the level observation data and 129 Sentinel-1 SAR images,the feasibility of the proposed early warning system was verified.Results show that the settlement deformation monitoring results by PS-InSAR can effectively cover the level observation values at the same time for case sluices,and the design of three-level settlement risk warning makes the application of PS-InSAR in the settlement risk warning of sluice feasible and operable.With the further development of InSAR technology,the application of engineering deformation early warning technology based on InSAR will be greatly promoted.关键词
