6、d.摘要该设计运用所学的知识完成木冲隧道左线的设计与施工。木冲隧道左线长1825m所经地区为典型的喀斯特地貌，地层为以砂岩、页岩、粉砂岩为主的寒武系地层。首先依据工程要求和设计规范确定隧道断面，然后根据“荷载-结构”法通过ANSYS对结构进行强度检算，根据检算结果配筋。隧道围岩等级主要以Ⅱ级、Ⅲ级、Ⅳ级和Ⅴ级为主。Ⅱ级和Ⅲ级围岩比较稳定设计采用全断面开挖，Ⅴ级和Ⅳ级围岩，由于围岩情况差，开挖断面较大设计采用中侧壁导坑法。隧道的主要施工方法：隧道采用新奥法施工，以喷射混凝土锚杆作为主要的支护手段，通过检测控制围岩变形，充分发挥围岩的自承能力。通过对围岩的力学
7、形态以及支护结构的工作状态的监控量测来评价设计施工水平并及时的改进与调整。隧道采用管棚作为超前支护，初期支护采用超前或径向注浆锚杆(小导管)、型钢钢架、钢格栅及挂网湿喷等施工技术，当围岩与初期支护基本稳定后施做二次衬砌关键词：高速公路隧道结构设计施工新奥法consciousness.Correctivemeasures:oneistosolvetheproblemofperformanceconceptdeviation;thetwoistodevelopadown-to-earthstyleofwork;threeistostrengthenthethr
