湖南科技大学潇湘学院本科生毕业设计（论文）－i－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－ii－ThedesigniscarriedoutontherightlineoftheroadtunneloftheauxiliaryroadinChongqing.Thetunnelisashorttunneloftheexpresswaytunnel，Tunnellength251.424m,designedfortwo-wayfourlanes，thedesignspeedis100km/h，Clearancewidthto10.75m.ofthethreecircularcurvedwallliningstructure,supportingstructureandsurroundingrockbearingtogether,andfullplaytheselfbearingcapacityofsurroundingrock.ThenewAustrianlawasthecoredesignoftunnelstructure,surroundingrocktunnelcontractiscomplex,IV,Vtwolevelsofsurroundingrockin.IVandVareusedatthebeginningofrocksection,waterprooflayer,compositeliningliningconsistingoftwo.Theinitialsupportforthesprayanchor,anchorbolt,shotcrete,steelmesh,commonsteelarch,twoliningbyformworkingconcrete.Instrictaccordancewiththeportaldesigncodefordesignofhighwaytunnel(GTJ-2004)oftherelevantprovisionsoftherelatedcheckingbyendwallportal;primarysupportaccordingtocodefordesignofhighwaytunnel(GTJ-2004),oftunnelengineeringandrelatedengineeringdesignexamples;twoliningusingLizhenggeotechnicalsoftwareversion6tocalculatetherelevantdata,andreinforcementcalculation;atthesametime,accordingtotherelevantreferencematerialsandengineeringexampleofatunnelconstructiondesign,designofdrainagedesignandmonitoring,renderingthecorrespondingdrawings.Keywords:shorttunnel;NATM;curvedwall;compositelining;sidewallportal－iii－录第一章设计任务及原始资料..................................................................11.1工程概况........................................................................................................11.2线路条件........................................................................................................11.3工程地质及水文地质条件............................................................................11.4经济技术条件................................................................................................1第二章隧道总体设计............................................................................32.1一般规定与设计原则......................................................................................32.1.1一般规定................................................................................................32.1.2设计原则..............................................................................................32.2主要技术标准及执行规范............................................................................42.2.1技术标准.........................................................
