摘　　要：为减小地铁车站建设中明挖法施工对现状地面交通疏导的不利影响,常采用盖挖法修筑临时路面系统,最大限度地维持路面交通状态,利用军用梁建立临时路面体系便是常用方式之一。以沈阳地铁4号线北大营站为研究对象,基于项目周边环境因素介绍了军用梁临时路面体系的设计思路、安装方法和受力特点。该方法可有效解决城市主干道下地铁车站基坑施工期间的道路交通疏导难题,对类似工程有一定的参考价值。In order to reduce the adverse impact of open cut method in subway station construction on the current ground traffic diversion,the covered excavation is often used to construct the temporary pavement system to maintain the road traffic state to the maximum extent,and the establishment of temporary pavement system by using military beams is one of the common ways.Taking Beidaying Station of Shenyang Metro Line 4 as the research object,based on the surrounding environmental factors of the project,this paper introduces the design idea,installation method and mechanical characteristics of the temporary pavement system of military beams.This method can effectively solve the road traffic diversion problem during the foundation pit construction of subway station under urban main roads,and has certain reference value for similar projects.
