复杂地质条件下铁路道岔区段架空施工技术研究

文章通过采用合理的措施解决线路间距小侵线的问题;解决道岔尖轨尖端难以加固的难题;针对流沙层进行架轨体系的整体性施工,"托轨"与"吊轨"的组合施工方法,有针对性地设计"型钢组合岔枕",保证施工期间铁路线安全运营,顺利完成了施工任务,取得了良好的效果。

Through adopting reasonable measures, this paper intends to solve the problem of small distance between lines and the difficulty of reinforcing the tip of point rail of turnout. Also, it carries out the integral construction of rack rail system for quicksand layer, and combine the construction methods of ＂supporting rail＂ and ＂lifting rail＂, in order to ensure the safe operation of the railway line during the construction period, thus, the construction task has been successfully completed and good results have been achieved by the targeted design of the ＂section steel combined switch tie＂.
