The analysis and research of the highway that has experienced landslides were conducted with the aim of mitigating the potential hazards caused by landslides.Taking the landslide remediation of a typical embankment on the Lechang-Guangzhu Expressway as the engineering background,three main unstable factors that contribute to landslide formation were identified through field investigations.Subsequently,the primary mechanical mechanisms behind the landslide formation were analyzed.Based on the formation mechanism and deformation characteristics of the landslide at the construction site,a new technology of using sub segmented control grouting steel flower pipe support reinforcement and multiple segmented control grouting inclined prestressed steel anchor pipe anchor cable combination structure reinforcement was proposed through scheme comparison,and the application effect was good.
