静宁隧道综合设计

专业：姓名：指导老师：

摘要：

随着科技的不断进步，现代隧道无论是从结构计算，还是从施工方法都较以前有了较大的飞跃，本设计课题为公路隧道，注重的是结构计算，重点研究新奥法施工。

本设计按照“新奥法”施工的要求，根据设计任务书的要求和参考公路隧道设计规范及其他各规范，对某山岭高速公路上的静宁隧道进行了综合设计。主要内容包括：工程地质的概况理解，并根据地质条件、水文条件等多方面的因素进行洞门设计、隧道横纵断面设计、隧道衬砌结构设计、路基路面防排水及管线沟槽设计以及施工组织设计，并进行了初期支护结构计算与隧道二次衬砌的结构计算，同时还完成了隧道通风、照明的计算及设计。最终达到内实外美、合理节约的原则完成本次静宁隧道的设计任务。

ABSTRACT

As science and technology progresses,the modern tunnel either from the structure calculation ,or from the construction methods have a greater than before,the design for tunnel project, focusing on the structure calculation , focus on New Austrian Tunneling Method.

According to the construction requirements of NATM ,according to the design requirement of the mission statement,Reference highway code for design of road tunnel and other desig n and construction specifications，the comprehensive design is made for JingNing Tunnel which is included in a highway of the mountainous area .This design paper includes the following several aspects : an overview of engineer geology to undeersrtand,according to geological conditions、according to geological conditions, hydrological conditions,and many other factors、portal design、tunnel cross-longthudinal
