摘　　要：随着我国的民生基础设施建立的加快,公路设施的建设也逐步完善。然而我国幅员辽阔,地形多变,尤其是我国西部地区海拔比较高,对于公路建设选线形成一定的难度。标准的公路选线时,不仅仅要考虑工程造价的合理性,还需要考虑很多综合的设计要求,如公路路线应当每个面都可以得到综合应用,公路的安全性始终作为核心要求贯穿于整个选线阶段。针对我国部分地区复杂的地质条件,探讨了公路路线的选线设计要求。具体包括公路选线的勘察步骤和内容,对所选公路线段做定性和定量判断,以判别地质的稳定性,提出经济美观的公路选线方案。With the increase of people＇s livelihood infrastructure to build,the construction of highway facilities also gradually improve.However,our country is a large country,and topography,especially altitude is higher,the western China form a certain difficulty for highway line selection.Standard of route selection,not only to consider the rationality of project cost,also need to consider many comprehensive design requirements,such as highway route should each side can get comprehensive application,the safety of the highway has been as a core demand throughout the line selection phase.In parts of the complex geological conditions in China,discusses the line selection of highway route design requirements.Including investigation steps and contents of road line selection,the selected road segment do qualitative and quantitative judgments,in judging the stability of the geological,economic and beautiful road line selection scheme is put forward.
