重载铁路隧道弹性支撑块式无砟轨道施工技术

Construction Technology of Elastic Support Block Ballastless Track in Heavy Haul Railway Tunnel

弹性支撑块式无砟轨道具备很多优点,比如:极佳的降噪性、结构较为简单等,在实施隧道养护的过程中,该施工技术有着较为普遍的运用。该技术当前在重载铁路隧道的铺设中也得到了应用。基于此,该文以弹性支撑块式无砟轨道结构组成和技术特征分析为出发点,探讨了重载铁路隧道弹性支撑块式无砟轨道施工技术。

The elastic support block ballastless track has many obvious advantages,such as excellent noise reduction and simple structure,it is widely used in the process of tunnel maintenance.Now,this technology is currently used in the laying of heavy rail tunnels as well.Based on this,this paper takes the analysis of the structural composition and technical characteristics of elastic support block ballastless track as the starting point,and then discusses the construction technology of elastic support block ballastless track in heavy haul railway tunnel.
