摘　　要：针对渝湘高速公路黔江隐患较大,且整治困难的长大顺层滑坡工程,通过现场详细勘查及室内试验分析,深入研究其分段滑动破坏机理,提出了具体施工整治措施:对破坏体进行削方处理,重点预加固已松动的潜在滑体前段,并采用锚索框架+钢管桩的综合治理方案,整治工作已完,坡体稳定,效果较好。Qianjiang this paper Against the long large bedding landslide engineering with larger risks and treatment difficulties along Chongqing-Changsha Highway, the failure mechanism of sectional sliding is further studied through in in site survey and indoor test analysis. Then the specific treatment measures are put forward： cut the damaged body; pre-reinforce the potential sliding body which has been loose; then adopt the anchor cable frame and steel pipe pile for treatment. The bedding landslide has been treated using the said measures and the slope is stable now, which achieved better effect.
