摘　　要：高原斜坡软土是在特定的地质条件和特定的气候环境下形成的具有成分复杂性、隐蔽性、膨胀性、蠕滑性等特殊性质的软土。对建筑其上的路基工程具有明显的危害性。通过内昆铁路老锅厂—李子沟区间高原斜坡软土地区抗滑支挡施工的实践 ,总结分析了高原斜坡软土对路基工程的危害 ,研究了适合高原斜坡软土路基抗滑支挡的技术措施 ,从实践过程中总结提出了治软、削坡减载、降水、加强支挡的关键技术 ,确保了本区段路基工程的安全稳定施工。其工程案例和研究成果对类似工程具有指导意义。The plateau slope soft clay is the special soft clay which forms in special geological condition and climatic environment and has the special characteristics such as the complex composition,cover-up,dilatability,flow to slide etc. The hazard of the slope soft clay to the roadbed is visible. Through the construction practice between Laoguochang-Lizigou of Neijiang-Kunming railway line,the risk of the plateau slope soft clay on the roadbed engineering is summarized. Some technical measures of solve soft, unloading,dewatering,strengthning surport,etc are amplied. This will ensure the stabilization and safety of the roadbed.The case and research will add more experiences for geotechnical engineers
