Abstract: In order to overcome the problems of long response time and high error in traditional settlement monitoring methods of highway, a differential settlement monitoring method based on BIM technology is proposed in this paper. According to the large-scale general finite element program and geotechnical theory, the numerical analysis model of highway expansion project is established to obtain the deformation value of highway expansion subgrade under different subgrade design parameters and subgrade materials. The differential settlement deformation mode and influencing factors of highway expansion are analysed. According to the analysis results, combined with SAR and BIM technology, the differential settlement of expressway expansion in the study area is monitored. The simulation results show that the response time of the proposed method is always less than 5 ms, the maximum monitoring error is only 0.067%, the response time is short and the monitoring error is small.
