摘　　要：针对G85云南麻柳湾至昭通高速公路四方石段路线方案中存在的安全问题,结合现场情况提出了解决思路,阐明了山区高速公路路线设计中贯彻落实"安全选线"、"地质选线"总体设计原则的重要性,最终确定的路线方案建设风险小、造价低、工程可靠度强、行车安全性好。并对山区高速公路路线比选中应注意的一些问题进行了总结。Combining checking with site conditions, this paper puts forward a solution to the security problem of Sifangshi section in G85 Yunnan Maliuwan-Zhaotong expressway, and illuminates the significance of implementation of overall ＂security selection＂ and ＂geological selection＂ design principles in route selection of mountainous expressway. Final design scheme has the features of lowers risk ofconstruction, costs less and higher engineering reliability and driving safety. Finally, this paper summarizes some problems should be paid attention to in route selection of mountainous expressway.
