摘要
随着城市化进程的不断推进,城市路网和轨道交通线网越来越广,在既有轨道交通区间隧道上方新建城市道路的情况也越来越多。为了保证隧道结构的安全和新建道路工程的顺利实施,以某新建道路工程和既有盾构法区间隧道为研究对象,利用三维数值模拟方法分析道路路基开挖、填筑施工对隧道结构的影响,在确保隧道结构安全的前提下确定合理的道路路基设计方案。
With the continuous advancement of urbanization,the urban road and rail transit networks are more extensive.And there are more urban roads built above the existing rail transit tunnels.To ensure the safety of the rail transit tunnel structure and the smooth implementation of the new road project,a new road project above the existing shield tunnel is taken as the research object.The influence of roadbed excavation and filling construction on tunnel structure is analyzed by a three-dimensional numerical simulation method,and a reasonable roadbed construction scheme is determined to ensure the safety of the tunnel structure.
