| 摘 要： | 当前运营的时速160 km以下有砟轨道（普货）隧道内轮廓尽寸难以满足大型养护机械（特别是大型清筛机）作业空间需求，通过对新建时速160 km以下电气化铁路、单双线隧道内轮廓主要影响因素（建筑限界、接触网悬挂方式及布置、大型养护机械空间需求、轨道结构型式、侧沟及电缆槽设置等）进行综合分析，确定单双线有砟轨道隧道内轮廓控制性尺寸，并初步拟定满足大型养护机械作业要求的内轮廓方案，在此基础上通过对内轮廓方案的结构安全性、经济性及施工便利性进行综合比较，确定推荐方案，该成果对铁路行业隧道通用图编制有一定的参考价值。 |

| Abstract: | The inner contour mode of ballast track railway tunnels with speed less than 160 km/h in China nowadays can not meet the requirement of large maintenance machinery. The main influencing factors of inner contour of electric railway tunnel and single line/double line tunnel, such as building boundary, hanging mode and layout of overhead catenary system, space requirement of large maintenance machinery and setting of ditch and cable trench, etc. are comprehensively analyzed. The control size of inner contour of singleline/doubleline ballast track railway tunnel is decided; and the inner contour mode is selected. The comparison between two inner contour modes is made in terms of structural safety, economical benefits and construction efficiency. The study results can provide reference for the selection of inner contour mode of ballast track railway tunnels in the future. |
| Keywords: | railway tunnel with speed less than 160 km/h general cargo transportation ballast track tunnel inner contour |
