摘　　要：中国已开通运营的地铁线路尤其是地下线路基本采用无砟轨道结构形式。无砟道床初期投资大,扣件选用技术标准严格,轨道几何形位调整困难。而有砟道床建设费用低、弹性良好、透水性强、噪声传播范围小、建设周期短、破坏修复时间短、自动化及机械化维修效率高、轨道超高和几何状态调整简单。运用ABAQUS建立隧道内车辆-轨道空间耦合模型分析地铁隧道中车轨振动特性,评价车辆运行的安全新、舒适性,论证隧道内有砟轨道应用可行性。Most currently operational subway lines in China,particularly underground sections,predominantly adopt ballastless track structures.While ballastless track beds require higher initial investment,stringent technical standards for fastener selection,and present difficulties in adjusting track geometric alignment,ballasted track beds demonstrate significant advantages including lower construction costs,superior elasticity,enhanced permeability,limited noise propagation range,shorter construction periods,faster post-damage restoration,higher efficiency in automated and mechanized maintenance,as well as simpler adjustment of track superelevation and geometric conditions.This study established a vehicle-track spatial coupling model within tunnel environments using ABAQUS software to analyze vibration characteristics of metro vehicles and tracks in subway tunnels.The investigation evaluated operational safety and ride comfort while demonstrating the feasibility of implementing ballasted tracks in subway tunnel applications.
