With the continuous development of highway construction in mountainous areas with complex topography,landform and geological conditions,slope instability and failure occur frequently during construction and operation period,which often leads to serious traffic safety accidents,affects the efficiency of highway operation and operation,and even causes serious casualties and property losses,resulting in adverse social effects.How to effectively monitor the safety of the slope and predict the deformation trend of the slope by monitoring data,so as to reduce or avoid the casualties and property losses caused by the deformation and destruction of the slope is very important.In this paper,the slope deformation monitoring system based on Beidou satellite is used to monitor the slope deformation.When making the slope deformation monitoring scheme,the finite element software Abaqus is used to establish the slope model,and combined with sensitivity analysis and grey correlation analysis,the layout of key monitoring areas and monitoring points is determined.Through monitoring data,a mathematical model is established to analyze the stability state and deformation trend of the slope.The following results can be achieved:(1)The main components of the slope deformation monitoring system based on Beidou satellite and the functions of each plate are studied.Compared with other deformation monitoring methods,the slope deformation monitoring system based on Beidou satellite has high accuracy,high efficiency,strong timeliness,higher autonomy and security,and can better meet the needs of slope deformation monitoring in China.(2)Various modes and influencing factors of slope deformation and failure are analyzed,and combined with numerical analysis software Abaqus,the key areas of deformation monitoring are determined,the optimization method of sensitivity analysis is established,and the pertinence of monitoring scheme is improved by optimization of sensitivity zoning.Detailed steps and calculation methods of optimization of grey correlation analysis are put forward,and the monitoring is reduced by optimization of grey correlation analysis.Redundancy of measurement scheme.Numerical simulation,sensitivity analysis and grey relational analysis improve the shortcomings of relying on empirical method to select points in slope monitoring projects,and improve the effectiveness and economy of monitoring schemes.(3)By comparing and analyzing various theories and methods of slope monitoring data processing,the grey system analysis method is recommended to process and analyze the slope monitoring data.Based on the deformation monitoring data,a grey GM(1,1)model is established to evaluate the slope stability and safety state and predict the deformation trend.(4)The slope deformation monitoring system based on Beidou satellite is applied to the left side slope of Yazhou Interchange Section of Pingluo Highway.The monitoring data and the actual technical condition of the slope are analyzed and compared,and good monitoring results are obtained.Beidou satellite is a global positioning and communication system independently developed in China.The slope deformation monitoring system based on Beidou satellite is a new method of slope monitoring.The optimization of slope deformation monitoring points is conducive to obtaining real and reliable monitoring data for Beidou satellite monitoring system.The grey model based on monitoring data can analyze and judge the stability state and deformation trend of the slope.It will provide necessary technical support for the development of highway disaster monitoring.
