隧道毕业设计摘要

摘要

本设计名称为“黄土梁隧道综合设计”，根据指导老师的要求及所给定的隧道拟建区的交通、气象、地质、水文等条件，主要设计了隧道平面图、隧道纵断面图、建筑限界内轮廓、紧急停车带内轮廓、隧道各级围岩衬砌结构及洞门、明洞结构、明洞暗洞的防排水措施和通风、照明等内容。

隧道除洞口段结合地形、地质条件设置，其余均按新奥法原理设计，采用柔性支护体系的复合式衬砌。初期支护采用锚喷支护，由喷射混凝土、锚杆、钢筋网和钢架等支护形式组合使用。由工程类比法，结合《公路隧道设计规范》拟定相应的支护形式,并通过必要的理论分析计算（收敛—约束法，荷载—结构法）进行校核。经验算，所有设计参数都符合规范要求，说明本设计是安全合理的。

隧道通风照明根据《公路隧道通风照明设计规范》并结合本设计，通风采用机械通风，照明采用不同功率的高压钠灯，并根据隧道总长分段进行照明。

关键词：公路隧道衬砌结构新奥法

Abstract

This design name as "Huang-tu-liang tunnel integrated design ". According to the requirements of guide teacher and the transportation, geology hydrology .etc, design the tunnel plan, the tunnel longitudinal profile, structural approach limit of tunnel, tunnel lining structure and tunnel portal, open cut tunnel structure, tunnel water handling, tunnel ventilation and tunnel lighting .etc.

Except the tunnel portal combine of the topography and geology conditions set, the others all design by the NATM, using the composite tunnel lining structure of flexible support. Primary lining using the bolting and shotcreting, be composed of shotcreting, bolting, steel mesh and steel arch support .etc supporting structure. By engineering analog method with 《Code for Design of Road Tunnel》studying out the homologous supporting structure, and checking by through the necessary computing(The convergence- restrain method and the load structure method). The analysis indicated that the design satisfied the design requirements stipulated in the Codes and Standards, then explained that the design is reasonable and safe.

Tunnel ventilation and lighting on the basis of 《Specifications for Design of Ventilation and Lighting of Highway Tunnel》combined with the design, adopt mechanical ventilation, and different types of laser HPSL (high pressure sodium lamp) combined with the length of the tunnel decorate subsection lighting.
