摘要:
为提高线路利用率和实现联网运输,我国新建高速、城际铁路多采取在已开通运营线路车站到发线咽喉区接入道岔的接轨方式引入既有客运站。为减小接轨施工对既有线路运营的干扰,本文以新建江苏南沿江城际铁路通过既有到发线引入江宁站的接轨工程为例,确定了施工改造范围,并分析了锁定轨温差、扣件纵向阻力及植筋锚固措施对18号无缝道岔受力和位移的影响,最后结合施工要求给出合理的施工建议,为类似工程提供理论支撑和技术参考。
Abstract:
In order to improve the utilization rate of the line and enable the access to the railway network, most of the newly-built high-speed railways and intercity railways in China are connected to the existing passenger stations by connecting switches in the throat area of the arrival and departure tracks of the stations of operating lines. For the purpose of reducing the interference of junction construction on the operation of the existing line, this paper took the junction of new Nanjing-Taicang Intercity Railway connecting to Jiangning Station through the existing arrival and departure track as an example, determined the scope of reconstruction, and analyzed the impact of the difference of fastening-down rail temperatures, the longitudinal resistance of fasteners and the anchorage measures of embedded bars on the stress and displacement of No. 18 continuous welded rail turnout, finally, reasonable construction suggestions were given in combination with construction requirements to provide theoretical support and technical reference for similar projects.
