长赣高铁浏阳至萍乡段经采空区域线路方案研究

Research on Route Through Goaf of Changsha to Ganzhou High-speed Railway between Liuyang and Pingxiang

长赣高铁呈南北向引入萍乡地区并穿越采空区域,区域内分布大型煤矿采空区及私采煤窑,历史悠久。考虑绕避周边大型煤矿采空区,结合车站站位需求,通过综合地质勘察手段,对线路方案及敷设方式进行综合比选,推荐采用下穿采空区两隧道方案。并结合研究成果,提出线路穿越采空区段方案的研究思路和建议。

The Changgan high-speed railway is introduced into the Pingxiang area in a north-south direction and passes through the goaf area.Large coal mine goafs and private coal mines are distributed in the area,with a long history.Considering avoiding the surrounding large coal mine goaf and considering the station location requirements,a comprehensive geological survey was conducted to compare and select the route plan and laying method.It is recommended to adopt the two tunnel scheme that passes through the goaf.And based on research results,research ideas and suggestions are proposed for the scheme of the line crossing goaf sections.
