公路隧道毕业设计(论文).docx

摘要本设计围绕重庆奥特莱斯配套道路工程隧道右线而进行，本隧道为高速公路隧道短隧道，隧道长251.424m，设计为双向四车道，设计车速为100km/h，建筑限界净宽为10.75m。衬砌采用三心圆曲墙式结构，支护结构和围岩共同承载，并充发挥出围岩的自承能力。以新奥法施工作为隧道结构设计指导，依托隧道围岩条件较复杂，包括IV、V级二种级别的围岩，相应围岩段均采用包含有初支、防水层、二衬组成的复合式衬砌。初期支护为喷锚支护，采用锚杆、喷射混凝土、钢筋网、钢拱架共同作用，二次衬砌采用模筑砼。洞门设计严格按照《公路隧道设计规范》（GTJ-2004）中的相关规定进行相关验算，采用端墙式洞门；初支根据《公路隧道设计规范》（GTJ-2004）、《隧道工程》和相关工程实例进行设计。二次衬砌利用理正岩土6.0版软件算出相关数据，并进行配筋计算；同时，根据相关参考资料和工程实例进行了隧道施工组织设计、防排水设计和监控量测的设计，绘制了相应的图纸。关键词：短隧道；新奥法；曲墙；复合式衬砌；端墙式洞门ABSTRACTThe design is carried out on the right line of the road tunnel of the auxiliary road in Chongqing. The tunnel is a short tunnel of the expressway tunnel，Tunnel length 251.424m, designed for two-way four lanes，the design speed is100km/h，Clearance width to 10.75m. of the three circular curved wall lining structure, supporting structure and surrounding rock bearing together, and full play the self bearing capacity of surrounding rock. The new Austrian law as the core design of tunnel structure, surrounding rock tunnel contract is complex, IV, V two levels of surrounding rock in. IV and V are used at the beginning of rock section, waterproof layer, composite lining lining consisting of two. The initial support for the spray anchor, anchor bolt, shotcrete, steel mesh, common steel arch, two lining by formworking concrete.In strict accordance with the portal design code for design of highway tunnel (GTJ-2004) of the relevant provisions of the related checking by end wall portal; primary support according to code for design of highway tunnel (GTJ-2004), of tunnel engineering and related engineering design examples; two lining using Lizheng geotechnical software version 6 to calculate the relevant data, and reinforcement calculation; at the same time, according to the relevant reference materials and engineering example of a tunnel construction design, design of drainage design and monitoring, rendering the corresponding drawings.Keywords: short tunnel; NATM; curved wall; composite lining; side wall portal目录第一章设计任务及原始资料31.1 工程概况31
