摘　　要：以贵州剑榕高速、G6京藏高速那曲至拉萨段为依托,针对山区高速及桥梁设计应考虑的多重因素进行具体分析。多重因素包括地形、地质、地震、施工期桥梁防护及特殊桥梁型式比选等,提出了具体措施,避免设计时考虑因素单一、局限于本专业内容的情况发生,为山区、峡谷、陡坡路段的路线及桥梁设计提供有益借鉴。Based on the Jianhe-Rongjiang Expressway in Guizhou and the Nagqu-Lhasa section of G6 Beijing-Tibet Expressway, a detailed analysis of the multiple factors that should be considered in the design of highways and bridges in mountainous areas is carried out, including terrain, geology, earthquake, bridge protection during construction, and comparison of special bridge types, etc. Specific measures are put forward to avoid the occurrence of single factor and limited to the contents of the discipline in the design, which provides a useful reference for the design of routes and bridges in mountainous areas, canyons, and steep-slope sections.
