摘　　要：路堑边坡开挖成形后,泥灰岩暴露在外,泥灰岩遇水崩解、失水干缩,破碎后强度大幅度降低,长期暴露在外经雨水作用后容易发生滑坡。本文结合工程实例,介绍重力式罩面及锚杆、喷射混凝土在处理滑坡时的应用。After the cutting slope is excavated and formed,the marlstone is exposed,the marlstone disintegrates and shrinks after water loss,and the strength of the broken marlstone is greatly reduced.After being exposed to the rain for a long time,landslides are likely to occur.Combining with engineering examples,this paper introduces the application of gravity cover,anchor rod and shotcrete in landslide treatment.

关 键 词：泥灰岩 滑坡 重力式罩面 锚杆 喷射混凝土
