【摘要】：新建山西中南部铁路通道为国内第一条设计轴重30 t的重载铁路。通过对我国客货混运线路双块式、长枕埋入式、弹性支承块式无砟轨道结构的组成及技术特点的对比分析,选用弹性支承块式无砟轨道作为该重载铁路隧道内无砟轨道结构形式。阐述了弹性支承块无砟轨道结构设计要点;给出了无砟轨道与隧底衔接的设计方案;分析了弹性支承块预制质量及轨道施工关键工序质量控制关键技术;提出了隧道排水系统设计优化建议。本文可为重载隧道内无砟轨道结构设计与施工提供借鉴。
[Abstract]:The new railway passage in central and southern Shanxi is the first heavy-haul railway with a designed axle load of 30 tons in China. The composition and technical characteristics of ballastless track structure of double block type, long pillow embedded type and elastic support block type on mixed passenger and cargo transportation lines in China are analyzed. The ballastless track with elastic support block is selected as the structure of ballastless track in the heavy haul railway tunnel. The main points of structure design of elastic bearing block ballastless track are expounded, the design scheme of the connection between ballastless track and tunnel bottom is given, the precast quality of elastic support block and the key technology of quality control in key working procedure of track construction are analyzed. The optimization suggestion of tunnel drainage system design is put forward. This paper can provide reference for the design and construction of ballastless track structure in heavy haul tunnel.
