...摘要本设计围绕会何家寨隧道右线而进行，本隧道为高速公路隧道中隧道，隧道长646m，设计为单向双车道，设计车速为80km/h，建筑限界净宽为10.25m。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。新奥法作为隧道结构设计的核心，合同段隧道围岩条件较复杂，有III、IV、V级三种级别的围岩，在IV、V围岩段均采用有初支、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，采用翼墙式洞门；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：复合式衬砌；翼墙式洞门；中隧道；新奥法；曲墙...ABSTRACTThisdesignwillaroundthehejiazaitunnelrightline，Thisisamediumlengthofhighwaytunnel，Tunnellengthof646m，ThisdesignisUnidi-rectionaldoublelane,Adesignspeedof80km/h.Constructionboundaryclearwidthis10.25m.LininguseThreeheartgardenCurvedwall,supportstructuresandRockSharedLoad.andMakefulluseofRockLoadbearing.NewAustrianTunnellingMethodisTunnelstructuredesigncore,Tunnelhasacomplicatedsurroundingrockcondition,haveIII、IV、Vcountryrock,Initialsupport、waterbarrierandsecondaryliningformCompoundliningoftheIII、IVcountryroc.InitialsupportforboltsupportShotcrete,ThetwoliningisBuildingconcrete.tunnelportaiswingwalltunnelportal.Instrictaccordancewiththeportaldesignat《Codeforhighwaytunneldesign》（GTJ-2004），Initialsupportaccordingto《Codeforhighwaytunneldesign》（GTJ-2004）design.twoliningutilizationofLiZhengrockandsoil6.0design.Atthesametime,AccordingtotherelevantinformationandengineeringexamplesConstructionorganizationdesignandwaterproofdrainageandMonitoringmeasurement.Keywords：compositelining;wingwalltunnelportal;Middletunnel;NATM;Curvedwall...目录第一章隧道工程概况.....................................................................................................11.1工程概况......................................................................................................................11.2工程地质........................................................................................................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...........................................................................32.2.1技术标准............................................................................................32.2.2执行规范............................................................................................42.3设计依据.......................................................................................................42.4隧道平面及纵断面设计...............................................................................42.5隧道横断面设计...........................................................................................52.5.1隧道建筑限界....................................................................................52.5.2隧道衬砌内轮廓线设计....................................................................62.6支护形式的选择...........................................................................................62.6.1洞门衬砌设计....................................................................................62.6.2洞身衬砌设计....................................................................................6第三章洞门设计与计算................................................................................................83.1洞口地质条件...............................................................................................83.1.1怀仁端洞口........................................................................................83.1.2赤水段洞口........................................................................................83.2洞门类型的选择...........................................................................................83.3洞门各部的尺寸拟定...................................................................................83.4计算参数.......................................................................................................93.5建筑材料的容许应力与容重.......................................................................93.6洞门稳定性验算...........................................................................................93.6.1计算洞门前一延米的平均高度........................................................93.6.2土压力计算......................................................................................103.6.3翼墙稳定性验算..............................................................................123.6.4主洞端墙验算..................................................................................14...3.6.5主洞与翼墙共同作用的..................................................................15第四章隧道初期支护设计与计算.........................................................................164.1概述.............................................................................................................164.2初期支护的设计.........................................................................................164.3V级围岩初期支护机构计算.......
