隧道内弹性支撑块无砟轨道施工关键技术

Key Technology in Construction of Elastic Bearing-block Ballastless Track within Tunnel

弹性支撑块整体道床具有施工进度快、抗列车冲击和抗疲劳作用能力强,寿命长,维修少,列车高速运行平稳等优点,阐述了在我国长度大于1 km且时速小于160 km/h的隧道及隧道群内的应用,详细介绍了弹性支撑块无砟轨道的施工工艺及施工注意事项,可为类似工程提供借鉴。

Elastic bearing-block solid bed has the advantages of fast construction progress,high train impact resistance,strong fatigue resistance,long service life,less maintenance and smooth high-speed train running.This paper sets forth its application in the length >lkm and the speed < 160km/h of the tunnel and tunnel group in China,and introduces the construction technology and construction gist of elastic bearing-block ballastless track in detail,which can be referenced for the similar projects.
