铁路框架桥应用于煤田采动区的研究

Research on Railway Frame Bridge Applied to Coal Mining Area

矿井铁路专用线平面展线往往需经过煤田采动区,这会给铁路桥梁结构的稳定带来安全隐患,严重时会导致桥毁而中断运营。本文以河南某矿铁路框架桥工程为例,对铁路框架桥在采动区的布置要点及适应泄洪及沉降所采用的构造措施进行了阐述,提出了能够适应不同需要的框架增高组合形式。

The horizontal extension of the mine railway special line often needs to pass through the coal mining area,which will bring great safety hazards to the stability of the railway bridge structure,and in severe cases,the bridge will be destroyed and the operation will be interrupted.This paper takes a railway frame bridge project in a mine in Henan as an example,expounds the main points of the railway frame bridge layout in the mining area and the structural measures adopted to adapt to flood discharge and settlement,and proposes the frame heightening combination form that fits different needs.
