1、XX高速公路XX隧道初步设计摘要此次设计为兰州至海口高速公路甘川界至XX段G7合同段XX到XX处的XX隧道左线主体的初步设计，全长1165.5m。起止桩号ZK20+230至ZK21+396，设计速度80km/h。本次任务主要内容包括有隧道平面设计、隧道纵断面设计、隧道横断面设计、隧道洞门设计、隧道初期支护设计、隧道二次衬砌设计、隧道防排水设计、隧道施工方法确定、隧道施工组织设计、工程数量计算等部分。隧道的线性设计主要依靠的是线路勘察时所取得的数据，进行平面、纵断面、横断面设计；洞门设计依靠地质情况进行比选；初期支护设计依据公路隧道规范进行设计；二
2、次衬砌设计时使用结构-荷载模型进行计算，用有限元分析法得出结构的内力，绘出结构内力图，再进行结构验算和配筋，最后确定衬砌结构的具体参数；防排水设计和施工方法是使用工程类比法进行相关设计。此次设计包括隧道设计时的各个方面，对各个部分进行初步设计，具体施工还需要更加详细的设计。【关键词】：有限元分析法；公路隧道；结构设计；隧道施工；IPreliminarydesignofXXtunnelinXXexpresswayName：XXXMajor：CvilEngineeringSupervisor：XXXAbstract：ThisdesignforLanz
