Abstract
This study proposes a comprehensive and 3D monitoring method for the subgrade settlement area of highway based on inter feremetric synthetic aperture radar(InSAR)technology,in order to ensure the operation safety of highway.Atmospheric delay phase is used to estimate the optimal solution of linear settlement rate and residual phase of elevation,the linear settle-ment value of the subgrade can be obtained.Differential interferograms are used to obtain nonlinear settlement values of the subgrade linear and nonlinear settlement values are integrated to obtain large-scale line of sight(LOS)directional settlement values.Offset tracking technology is used to obtain small-scale LOS directional settlement values.The multi-level settlement fusion results of highway foundation are obtained by fusing the two methods.3D decomposition of the fusion results is per-formed to obtain the settlement value of the highway subgrade in 3D space.The experimental results indicate that the subgrade settlement values monitored by the proposed method retain the high-resolution characteristics,and the relationship between groundwater level and settlement at different positions of the highway subgrade is monitored,and the proposed method has high accuracy in monitoring the vertical,east,and north settlement values of highway subgrade.The proposed method can ac-curately monitor changes in subgrade settlement,which is of great significance for ensuring the safety of highway operation.关键词
