小林子冲1号隧道工程设计 摘要 本设计为“ 小林子冲1号隧道工程设计”，设计速度100km/h，按单向三车道设计，隧道全长 1015m。主要设计内容如下：隧道总体设计、隧道横断面设计、隧道洞门设计、隧道衬砌设计、隧道防排水设计、隧道通风设计、隧道施工设计、隧道照明设计（专题）。 总体设计主要进行了隧道平面设计和隧道纵断面设计。隧道横断面设计进行了建筑限界和衬砌内轮廓的拟定。隧道洞门选择端墙式洞门与削竹式洞门，通风方式采用射流式通风。衬砌采用复合式衬砌，初期支护采用锚杆、喷射混凝土和钢筋网等，二次衬砌采用模筑混凝土或模筑钢筋混凝土，运用软件同济曙光对二次衬砌进行验算。隧道采用新奥法施工，III、IV V级围岩采用上下预留核心土短台阶法及单侧壁导坑法施工。 关键词：洞门设计；衬砌设计；同济曙光；施工设计 SMALL LIN ZI CHONG NO.1 TUNNEL DESIGN ABSTRACT The design for the "small lin zi chong no.1 tunnel design", the design speed of 100km / h, according to one-way three lanes design, tunnel line length of 1015m. The main design content are as follows: the overall design of the tunnel, the tunnel cross-sectional design, the tunnel portal design, design of the tunnel lining, tunnel waterproof and drainage design, tunnel ventilating and lighting design, tunnel construction design,tunnel lighting design (topics ). The overall design of the tunnel mainly for graphic design and design of the tunnel longitudinal section. Tunnel cross section design of the building and the inner lining bounding contour drawn. Select the side wall tunnel portal Portal and cut bamboo tunnel portal, ventilation use jet ventilation. Lining use composite lining, initial support use bolt, sprayed concrete and steel nets, secondary lining concrete building use mold or mold built of reinforced concrete, the use of the GeoFBA software using direct method for the secondary lining were just checking. Tunnel use NATM, level III、IV Grade rock upper and lower short step method of construction, V Grade Rock Reservation Core Soil short upper and lower stairs law and unilateral Heading Method. Key words: The Portal design; Design for concrete lining; GeoFBA; Construction Design  目录 1.概况 1 1.1 地理位置 1 1.2 地形地貌 1 1.3 隧道地质 3 1.4 气象与水文 4 1.5 主要技术指标 4 1.6 设计依据 5 2.总体设计 5 2.1 隧道建筑界限 5 2.2 内轮廓设计 6 3 隧道洞门设计 7 3.1 洞门设计原则 8 3.2 洞门位置选择 8 3.3 洞门确定 8 3.3.1 洞门设计参数 9 3.4 进口洞门验算 10 3.4.1倾覆稳定性验算 10 3.4.2滑动稳定性验算 11 3.4.3基底应力及力偏心距验算 11 3.4.4
