摘　　要：双联拱隧道在特殊地质及地形条件地区的公路建设中应用广泛。依据第四届全国高校城市地下空间工程专业大学生模型设计竞赛题目,以巴西白卡纸为原材料制作双联拱隧道结构模型,采用理论计算、模型试验和数值模拟相结合的方法,对双联拱隧道模型进行设计及优化,得到模型结构的承载能力和变形特性,模型极限承载力和破坏形态可为结构优化与局部加固提供参照,对地下空间模型结构设计竞赛和实际隧道的设计具有一定借鉴意义。Double arch tunnel is widely used in highway construction in special geological and topographical conditions.According to the title of the 4th national competition for model design of university students majoring in urban underground space engineering,the double arch tunnel structure model is made of Brazilian white cardboard.The double arch tunnel model is designed and optimized by combining theoretical calculation,model test and numerical simulation.In this way,the bearing capacity and deformation characteristics of the model structure are obtained.The ultimate bearing capacity and failure mode of the model can provide reference for structural optimization and local reinforcement,which have certain reference significance for the design competition of underground space model structure and actual tunnel design.
