Taking the deep excavation cut section treatment of Jing-Tong highway as an example,combining with the landslide geology environ-ment and landslide geotechnical characteristics,the paper analyzes landslide causes and categories,and calculates residual landslide sliding force with transmit coefficient slice method. Through indoor geotechnical test and in-situ test and counter-analysis method,based on technical and eco-nomic conditions,it analyzes and selects anti-sliding landslide processing scheme,and carries out engineering design,and finally obtains great effect.%以靖通高速公路某深路堑段滑坡治理为例，结合该滑坡场地地质环境与滑坡岩土体特征，分析了滑坡成因及类型，依据传递系数法对滑坡剩余下滑力进行计算，计算参数通过室内土工试验和现场原位测试并结合反分析方法综合确定，通过技术和经济条件分析对比选取抗滑桩治理滑坡方案，并进行工程设计，获得良好效果。
