1、 I 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

2、；二次衬 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； II Preliminary design of XX tunnel in XX expressway Abstract： This design for Lanzhou to Haikou highway Gan-Chuan Part to Yaod

5、ained, to plane, profile, cross-sectional design; Tunnel exit and entrance design rely on geology for coMParison; A design basis for highway tunnel lining design specification; Secondary lining design using Load- Structure model to calculate, using ANSYS software the internal force of the structure,

6、 draw the structure within, trying to get the internal force data, structural reinforcement and check again, and finally determine the specific parameters of the lining structure; Waterproof and drainage design and construction method is to use the engineering analogy method for related design. This design including all aspects of the tunnel design, to the preliminary design of each part, the specific construction also need more detailed design.
