摘　　要：以烟台市塔山北路快速路工程为例,提出山地城市地下快速路的总体设计、交叉节点、防灾救援及智慧隧道方案.根据"两山夹一城"的地势条件,对穿城段方案进行了浅埋暗挖、叠层明挖和平铺明挖的综合比选,推荐平铺明挖方案,采用隧-桥-隧结合形式,实现"长隧短做",有效地降低了工程风险、难度和造价,以及机电系统的复杂程度和运维难度,为相似工程的方案和设计提供了可参考的经验.Taking the Yantai City North Tashan Road Expressway Project as an example,the overall design,intersecting node,hazard prevention rescue and wisdom tunnel scheme of the underground expressway in the mountainous city are introduced.Based on the topographical conditions of"one city in two mountains",the shallow buried excavation,laminated open excavation and flat open excavation of the scheme of crossing-city section are comprehensively compared and selected.The flat open excavation scheme is recommended.The tunnel-bridge-tunnel combined type is adopted to realize the"short construction for long tunnel",which effectively reduces the engineering risk,difficulty and cost,and decreases the complexity and the operating and maintaining difficulties electromechanical system.The referable experience can be provided for the schemes and designs of the similar projects.
