摘要
结合第四届全国城市地下空间工程专业大学生模型设计竞赛,建立了双联拱隧道数值模型,分析了各计算工况。根据有限元数值模型计算结果,对各工况下模型顶部竖向位移、构件最大侧向位移及构件最大轴力对比分析,提出了隧道支护结构模型优化设计建议。
Based on the fourth national model design competition for college students majoring in urban underground space engineering,the numerical model of double-arch tunnel is established,and the calculation conditions are analyzed.According to the calculation results of the finite element numerical model,this paper makes a comparative analysis of the vertical displacement at the top of the model,the maximum lateral displacement and the maximum axial force of the members under various working conditions,and puts forward some suggestions for the optimal design of the tunnel supporting structure model.
