高速铁路无碴轨道板封边方案的技术经济比选

摘要

Combining with the fact of the ballastless track plates along Beijing-Shanghai express railway,the paper explores the sealing scheme for the gap edges between the track plate and the bottom plates,compares and analyzes the angle scheme and mortar scheme of the edge sealing from the technical and economic aspects,and selects the angle steel edge sealing scheme,so as to provide certain direction for the future ballastless track construction along express railways.%结合京沪高速铁路无碴轨道轨道板实际情况,探讨了轨道板和底板之间的缝隙边缘密封方案,通过对封边采用的角钢方案和砂浆方案从技术经济角度进行了对比分析,最终选定角钢封边方案,为今后高速铁路无碴轨道施工提供了一定指导。
