摘　　要：为设计惠罗高速公路K72+705~MK0+200段右侧滑坡防护方案,本文根据野外地质调绘确定主滑方向及滑动规律,利用钻探工作揭露滑体、滑带、滑床岩性、产状及规模,运用工程地质类比法及力学稳定性分析确定防护比选方案,对方案存在问题进行探讨,最后综合各方因素以及施工安全,确定应急抢险治理设计方案。To design the prevention program of K72 ＋ 705 ~ MK0 ＋ 200 in the Huishui-Luodian expressway,the main slip direction and sliding laws have been determined according to the field geological survey. The sliding body,sliding zone,sliding bed lithology,inclination and scale has been exposed based on the drilling working. The prevention program has been confirmed based on the engineering geology analogy and mechanical stability analysis of the slope. At last,the design scheme of emergency management has been determined considering all the factors including the construction safety.
