摘　　要：乌鲁木齐外环线扩容改建工程穿越雅玛里克山,新建雅玛里克山连拱隧道位于既有雅山隧道上方,新建隧道与既有隧道为平行小净距隧道。针对雅玛里克山隧道的线位布置、衬砌结构选型、施工工法、爆破振速控制等方面的设计进行介绍,可为同类型工程设计和研究提供借鉴和指导。Urumqi Outer Ring Line Extension Reconstruction Project passes through Yamalike Mountain. The newly built Yamalike Mountain Multi Arch Tunnel is located at the upper of the existing Yamalike Mountain Tunnel. The newly built tunnel and the existing tunnel are the paralleling and small-spacing tunnels. The article introduces the design of Yamalike Mountain Tunnel from its alignment layout, lining structural selection,construction method and blasting vibration speed control, which can be referred for the design and study of the similar tunnels.

关 键 词：既有隧道 平行小净距 连拱隧道 三导洞法 振速控制
