迫在眉睫。
本设计课题为高速公路隧道，重点研究隧道内轮廓的确定，隧道通风的设计，二次衬砌的设计和新奥法施工。
该高速公路隧道为分离式单向行驶两车道隧道，左线全长298m，围岩的基本情况为：Ⅱ级围岩长155m；Ⅲ级围岩长90m；Ⅳ级围岩长53m。
隧道洞门设计成翼墙式洞门；隧道采用新奥法施工，隧道衬砌采用复合式衬砌；隧道开挖Ⅱ、Ⅲ级围岩使用全断面开挖法，Ⅳ级围岩使用长台阶分部开挖法，采用钻爆法开挖；隧道的辅助施工方法有超前小导管注浆和超前锚杆；隧道通风方式主要为自然通风，兼有机械通风。
隧道经过多次计算和验算后，洞门、衬砌和通风等均满足要求，可以正常施工。

XXX HIGHWAY TUNNEL DESIGN
[Abstract]
After the reform and opening-up policy, the national economy is booming, highway passenger-cargo traffic volume increase substantially, the existing highway capacity manual insufficient contradiction have become increasingly prominent, the urgent need to improve road level and technical standard, the highway will become the mainstream of road construction in China. However highway tunnel of technical and economic conditions needed than railway tunnel and other tunnel project of highway tunnel, therefore, design concept, design method and construction method of exploration and research is very necessary. Because of linear and highway rating by the requirement, highway slope servants and inevitable requirement more and more using tunnel scheme, which not only can overcome the terrain and elevation obstacles, improve lines, improve speed and shorten mileage, save fuel, save time, reduce the damage to vegetation, protect the ecological environment; Can effectively prevent rockfalls, landslide, collapse avalanches and natural conditions, enhances the parameters of safety, reliability and comfort at the same time, and local environmental photograph coordination level security the natural landscape.
Therefore, from the economic benefit, ecological benefit and international big trend, safe, economic and reasonable, the artistic research of highway tunnel is imminent.
This design task for highway tunnel, the key research tunnel profile, the design of
