摘　　要：城市明挖隧道通常采用现浇钢筋混凝土闭合框架结构,单层隧道可按沿隧道纵向长度为1m的平面框架计算,双层共板隧道结构受力与单层隧道存在明显不同之处。结合某实际工程,对双层共板隧道结构模型建立、荷载加载方式、受力特点进行计算分析和对比,可为类似工程设计提供一定参考。Urban open cut tunnels usually adopt a cast-in-place reinforced concrete closed frame structure,and single-layer tunnels can be calculated as a plane frame with a longitudinal length of 1 m along the tunnel.There are significant differences in the stress of the doublelayer common plate tunnel structure compared to single-layer tunnels.Based on a practical project,the establishment of a double layer tunnel structure model,load loading methods,and stress characteristics are calculated,analyzed,and compared,which can provide certain reference for similar engineering designs.
