摘要
研究目的:以福厦铁路站前工程Ⅲ标段过渡段施工为例,阐述了过渡段的施工方法与处理形式,以解决在过渡段处因路基与桥涵、隧道等结构物刚度差别较大,引起轨道刚度突变,和因不同结构的沉降不一致而导致轨面不平顺,从而引起列车与线路结构的相互作用加强,影响线路结构的稳定的问题。研究结果:福厦铁路站前工程Ⅲ标段过渡段施工已基本完成,根据已完成的过渡段的检测结果和沉降观测数据分析显示,路基沉降变形已基本趋于稳定,完全能够保证路基工后沉降的要求。
Research purposes:Taking construction of transition section of BiddingⅢof pre-station engineering of Fuzhou-Xiamen Railway,the analyses of construction methods and treatment ways of transition section are made for the purposes of solving the following problems:(1)sudden change of track rigidity in transition section caused by big differences in rigidity between subgrade and bridge,culvert,tunnel;(2)the irregularity of rail surface caused by the different settlements of different structures;(3)the instabilit...
