摘要
目前,隧道工程也已经成为公路系统中的重要组成部分。它对优化道路线形、缩短公路里程有重大影响;同时对促进周边地区环境保护、经济发展及国防建设也具有深远影响。本设计是虎山隧道施工组织设计。
虎山隧道设计为公路Ⅲ级,采用双向两车道,人字坡设计。隧道全长840m,出口段为V级围岩,采用翼墙式洞门。洞身穿越III、IV、V级围岩。设计中,根据隧道的基本情况,通过对施工方案的必选,确定了采用新奥法原理设计的复合衬砌方案,初期支护主要为锚喷混凝土,二次衬砌采用模筑混凝土。III级围岩施工时采用全断面法开挖,IV级围岩施工时采用上下台阶法开挖,V级洞身段先超前加固再台阶法开挖,并针对性的设计了各施工的具体工序及流程。隧道内设有完善的排水设施以及运营通风、照明、供电等附属工程,保证了隧道的安全和正常运营。

Abstract
Tunnel project also has e an important part of road system. It is to optimize road alignment, shorten the length of roads are important influence, To promote environmental protection and surrounding areas for economic development and national defense construction and far-reaching paper is designed for anization of HuShan Tunnel.
The load is designed as Ⅲ class, adopting 2 directions with 2 lanes, herringbone slope design. The total length of HuShan Tunnel is 840m. The entering section’s rocondition is classified as V, chooseing wing wall tunnel portal. The tunnel had been through III、IV、V-class rocks. In this paper, after parison and selection of construction scheme, determines to use NATM to posite lining, according to the basic situation of the tunnel. The early support is mainly use anchor shotcrete, using lining concrete to build the model. Using whole cross section excavation method for the construction of the holes of III-class rock construction. Using Steps method for the construction of the tunnel of IV-class rocks, and Advance reinforcement excavation pit method for V-class rocks. And designed the concrete construction process at the same time. With the internal operation of the tunnel water system, ventilation, lighting, electricity and other ancillary works, the driving safety had been insured during operation phase.
