摘要:: 山区高速铁路桥隧比重高，受地形、地质等条件影响，站场工程复杂。本文结合多条山区高速铁路站场工程实例，分别从车站分布、车站规模及站址、站型、站坪等方面分析山区高速铁路站场工程系列关键技术。研究结果表明：（1）西南山区高速铁路平均站间距小于西北地区，但高于东部（京沪高速铁路除外）、南部及东北地区；（2）山区高速铁路以2个站台规模的小型客运站为主，约占65.8%，明显高于其他平原地区高速铁路；（3）山区高速铁路展线系数并不比平原地区高，车站分布及站址设置是影响山区高速铁路正线绕行长度的关键因素；（4）复杂地形地质条件下车站站型和站坪应根据工程条件因地制宜创新设置。研究结论可为复杂艰险山区高速铁路站场工程设计提供指导和借鉴。

Abstract:: With a high ratio of bridges and tunnels for the high-speed railways in mountainous areas, the construction of stations and yards are complicated due to the influence of topographical and geological conditions. This paper takes several high-speed railways stations and yards in mountainous areas as study cases, to analyze the key technologies related from the aspects of the distribution, scale, location, type, and site of stations. The results show that: (1) The average spacing of high-speed railways stations in the mountainous area of Southwest China is smaller than that in Northwest China, but higher than those in East China (except Beijing-Shanghai High-speed Railway), South China, and Northeast China. (2) Small passenger stations with two platforms are prevailing for high-speed railways in the mountainous areas, accounting for about 65.8%, significantly higher than other HSRs in plain areas. (3) The coefficient of extension line of HSRs in mountainous areas is not higher than that in plain area, and the distribution of stations and the setting of station location are the key factors affecting the bypass length of the open track of high-speed railways in mountainous areas. (4) The type and site of station shall be designed out of the box according to the local complex topographical and geological conditions. The conclusions can be taken as a guidance and reference for the design of high-speed railways stations and yards in complex mountainous areas.
