摘　　要：随着城市建设的飞速发展,城市隧道成为构建城市立体路网体系的重要组成部分,以合肥市骆岗生态公园花园大道隧道工程为例,详细介绍了花园大道隧道结构设计重难点,并运用有限元分析软件对双层箱型顶板断面进行三维计算分析,通过工程实践印证了结构设计是合理、安全、经济的,可为今后类似建设条件下的隧道设计提供参考。With the rapid development of urban construction,urban tunnels have become an important part of the urban three-dimensional road network system.Taking the Garden Avenue Tunnel Project in Luogang Ecological Park,Hefei City as an example,this paper introduces in detail the key points and difficulties in the structural design of the Garden Avenue Tunnel,and uses the finite element analysis software to conduct three-dimensional calculation and analysis on the double-layer box-shaped top plate section.The engineering practice has verified that the structural design is reasonable,safe and economical,which can provide a reference for the tunnel design under similar construction conditions in the future.
