.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...ABSTRACTThis design will around the hejiazai tunnel right line，This is a medium length ofhighway tunnel，Tunnel length of 646m，This design is Unidi- rectional double lane,Adesign speed of 80 km/h.Construction boundary clear width is 10.25m.
