摘　　要：西南地区工程建设条件复杂,高速公路在建设过程中面临工程地质、生态环保及交通安全等问题。结合西南地区多个高速公路项目,对工程穿越的泥石流频发区、膨胀岩区、岩溶地区、顺层高边坡及高陡斜坡存在的设计难题进行分析,提出解决方案;对工程涉及的环境保护与交通安全问题进行梳理,结合工程经验提出建议措施,对类似地区的公路总体设计具有一定的借鉴意义。The physical conditions in the southwest region are complex, and the expressway construction faces problems such as geology, ecological environment protection and traffic safety during the construction process. In the paper, combining several expressway projects in the southwest region, the problems that when carrying out design faces is analyzed, such as the frequent debris flow areas, expansive rock areas, and karst areas, high and steep slopes etc., and solutions are proposed. The environmental protection and traffic safety issues involved in the project are sort out, and suggestions are put forward based on engineering experience, which have certain reference meaning for the overall design of highways in similar areas.
