Taking the landslide on the right side of DK0 +585~DK0 +780 section of Yongji Expressway as a case study,the sensor layout scheme is designed,and the automatic monitoring and early warning system is used to monitor and warn the slope all day and au-tomatically.The system timely and accurately identifies every deformation acceleration process of the slope and plays a warning role.Through the analysis of the monitoring data,the deformation characteristics are summarized,and combined with the site inspection and engineering geology,the comprehensive safety evaluation is carried out.The results show that the landslide is still in an unstable state,and the main inducing factor is rainfall.Automatic monitoring and early warning can accurately grasp the deformation and acceleration process of landslide,and effectively guarantee the operation safety of expressway.
