【摘要】 宏观上论述了我国西部道路交通开发中地质环境基本特点、主要工程地质问题及工程可行性，并着重指出，地形复杂、地壳强活动、滑坡泥石流、冻土和风沙等灾害构成了交通开发中施工、养护的突出问题，部分干旱区水源匮乏矛盾尤为突出，但工程地质环境仍具可选择的条件。更多还原

【Abstract】 This paper comprehensively discussed basic characteristics of geological environment,main engineering geological problems and engineering feasibility in Land traffic exploitation in West China.It is emphasized that topographic complexity and hazards such as intensive activity of the crust,landslide debris flow,frozen soil and blozen sands,etc.,are the primary problems in land traffic construction and maintainance.In some arid regions,lack of water resource is much striking.However,there are still some available conditions which can be chosen in such engineering geological environment.更多还原
