【摘要】 无碴轨道底板作为无碴轨道下部基础的主要承载层,其施工质量要求很高,结合隧道作业空间狭小的特点,如何快速、优质完成底板的施工,便成为客运专线隧道施工中的一个重点。通过对大别山隧道无碴轨道底板施工的介绍,以此期望为其它客运专线隧道底板施工提供经验及借鉴。更多还原

【Abstract】 As the major load-bearing layer of the understructure of the non-ballast track,the floor slab of the non-ballast track system has high requirements in construction quality.Due to the narrow working space inside the tunnels,the rapid and high-quality construction of the floor slAbs inside tunnels becomes one of the most important aspects in the construction of passenger-dedicated railway tunnels.The construction of the floor slAbs of the non-ballast track system inside Dabieshan tunnel is presented in the paper,which can provide reference for the construction of the floor slAbs in other passenger-dedicated railway tunnels.更多还原
