摘　　要：以某山区高速公路跨深V峡谷特大桥工程为背景,从结构特点、施工难度、工程经济及景观效果等方面,对适于桥址处地形、地貌和地质条件的4种桥型方案进行比选;经综合考虑,钢管混凝土拱桥因具有造价适中、技术成熟、造型美观、对环境影响较小等优点而作为推荐方案。在此基础上,对山区高速公路桥型方案的比选提出建议。Based on the engineering project of an super large expressway bridge crossing deep V Canyonin mountainous area,four bridge schemes suitable for the landform and geological conditions are compared in this paper from the following aspects:structural characteristics,construction difficulty,engineering economy and landscape effect.After comprehensive consideration,the concrete-filled steel tubular arch bridge scheme is recommended for the advantages of reasonable cost,mature construction technology,graceful shape and little impact on the environment.Finally,some suggestionson the comparison and selection of highway bridge type schemes in mountainous areas are given for reference.
