1、摘要本设计为陆家嘴单向双车道隧道设计，隧道进洞里程为DK8+772m，出洞里程为DK8+827m，全长55m；设计时速100km/h，隧道最大埋深20m。根据提供的工程地质资料及相关设计标准，进行了此次设计。设计中利用作图法确定进出口里程、边仰坡开挖线及隧道长度；选用翼墙式洞门并进行强度和偏心验算；根据工程类比法采用复合式衬砌：初期支护采用喷锚支护，模筑混凝土作为二次衬砌，二者共同作用来形成整个隧道的结构支护体系，根据规范数据作衬砌横断面图，依此计算结构内力并检算其抗压、抗拉强度。该隧道设计主要包含四个部分的内容。第一部分为洞口设计，包括隧道里程和开挖线的确定；第二部分为洞门设计，包括洞

2、门类型的选择、洞门设计和洞门验算；第三部分为衬砌设计，包括支护形式的选择、衬砌设计和衬砌验算，其中衬砌验算是用Fortran程序完成的；第四部分是施工组织设计，主要阐述了设计依据、工程概况和一些具体的施工措施，同时对机具的配备和人力的安排提出了建议。关键词：公路隧道；双车道；翼墙式洞门；复合式衬砌AbstractThedesignisoftheLujiazuione-waytwo-lanetunneldesign.TheMilegeofthetunnelentranceisDK8+772m,theMilegeofthetunnelexitisDK8+827m,andtotallength
