摘要
本设计对隧道的设计内容主要包括从地质、地形、经济、环保的方面对路线的方案确定;对隧道平面、纵断面、横断面的设计以满足经济、合理、安全、施工容易等要求;对隧道衬砌结构设计和计算以保证衬砌能够满足围岩压力的要求;在排水设计遵循“防、排、截、堵相结合,因地制宜,综合治理”的原则下,采用完整的防排水体系,使隧道内防水可靠,排水通畅,保证运营期间隧道内不渗不漏,基本干燥;根据隧道进出口地形和工程地质条件,结合开挖边仰坡的稳定性及洞口防排水需要,选用经济、美观并有利于视线诱导的洞门形式;在考虑尽量少刷坡和隧道“早进洞、晚出洞”的原则确定洞门位置;选择合适隧道施工方案使之满足本隧道围岩节理发育、围岩不稳定易发生变形等要求;隧道通风、照明的设计和计算。

Abstract
The routes selection of the tunnel design are mainly from the geological, topographical, economic, and environmental protection programs . Plane of the tunnel, vertical section of the tunnel, cross-sectional of the tunnel design to meet the needs of the economy, a reasonable, safe, easy construction, etc. Structural design of tunnel lining and calculation to ensure the lining to meet the requirements of pressure of surrounding rock . In the drainage design to follow, "defense, platoon, section, block by combining the light of local conditions in a comprehensive way" principle, adopting a complete drainage system make water inside the tunnel reliable, efficient drainage to ensure that operators do not dialysis during the tunnel does not leak, basic dry; Import and Export under the tunnel and engineering geological conditions of the terrain, combined with the excavation side slope stability and Yang drainage holes need to choose the economic, aesthetic and conducive to the form of attention-induced portal; Brush as little as possible in considering the slope and tunnel "geting in the tunnel portal as aerly as possible and getting out the tunnel portal as late as possible" principle to determine the location of Portal; Choosing the right tunnel construction program to meet the joint development of tunnel surrounding rock, rock deformation prone to instability, etc.; Designing and calculating of ventilation and illumination of the tunnel.
Key words:routes selection;structure lining; Construction method ; structural calculation;drainage;Portal;Ventilation;illumination
