摘　　要：由于黄土具有结构性、欠压密性和土结构性受损易发生湿陷等特性,再加上公路连拱隧道施工开挖工序多,结构受力复杂。这就对黄土连拱隧道的设计提出了更高的要求。结合青银国道主干线离石至军渡(晋陕界)段离石和王家会两条黄土连拱隧道工程,对黄土连拱隧道的洞门口设计、洞身设计、中隔墙及其基础设计、隧道的防排水系统设计和施工方案的设计进行了探讨,提出了合理的设计方案。Loess has the characteristics of structural properties, such as incomplete consolidation , collapsibility ; And the multi-arch tunnel of highway has complex excavation steps and structure stress. So the loess multi-arch tunnel is difficult to construct with soft surrounding rock, large excavation section and strict technology. According to the projects of Lishi and Wangjiahui loess multi-arch tunnels in Qingyin main line highway from Lishi to Jundu ,the design of tunnel, which contains design of tunnel doorway, tunnel structure, mid-partition wall and its foundation, waterproofing drainage system and construction plan, is discussed. And a reasonable design plan is put forward, which is benefit for the design of loess multi-arch tunnel.
