Analysis of Factors Influencing the Instability of Anti-dip Slate Slope of Highways in Mountainous Areas and Landslide Treatment Scheme
Slate is widely distributed in China and the slate slope is unstable during the construction of the highway.Through the analysis of the instability of the slate slope of the Guanxin Highway,the main factors influencing the instability of the slate slope are summarized,that is,the unfavorable topography,mechanical characteristics under the influence of slate joints,the impact of rainfall infiltration and the weakness of temporary measures for the slope excavation.The treatment scheme of deloading through rock and soil removal+anchor rod and anchor cable+micro pile reinforcement is proposed,which will provide certain reference value for the design of slate slopes and the treatment of slate landslide.
