1、南京工业大学本科生毕业设计（论文）许府巷~南京站地铁区间隧道设计摘要此段设计为许府巷站至南京站地铁区间隧道设计，本标段工程隧道纵坡为V形，最大纵坡为25‰。据初步调查，区间隧道将在内某河下方穿过、共有8栋建筑物位于隧道线路的侧下方（指四层以上房屋）。区间隧道最小曲线半径为R=800m。其埋深在8.0m～14.0m之间。该区间为K12+661.09～K14+117.95，上下行线总长为2913.72m，为了满足含泵站、检修井、集水管使用需要，在K13+367.50处设置联络通道，总长为14.2m。本工程设计基准期为100年，采用具有一定刚度的单层柔性衬砌。管片尺

2、寸为：内径5.5m,厚度为350mm，宽度为1.2m。管片采用六个分块：一个小封顶块K、两个邻接块B、三个标准块A。本次设计的主要内容包括：管片方案的确定、隧道管片结构设计、联络通道二衬结构设计、施工组织设计、沉降分析以及防水设计。关键词：地铁区间隧道管片联络通道施工组织设计IAbstractDesignofmetrotunnelfromZhangfuyuantoXinjiekouAbstractThisprojectformetrotunnelfromZhangfuyuantoXinjiekouisatwin-tracktunnel,whichmainlyi
