要: 厦门市机场路一期工程中的万石山地下互通式立交为目前我国第 1 座大型暗挖地下互通式立交, 结构种类
繁多, 施工工序复杂, 既有平面分岔结构, 又有上下交叉结构。通过分段扩大的方式实现平面分岔功能, 从大跨结构
到不对称连拱结构, 到小净距结构, 从普通隧道的开挖到既有洞室的改造, 此立交覆盖了目前山岭隧道几乎所有的
结构型式, 创造了单洞 25. 8 m 的开挖跨度, 小净距中夹岩仅 1. 42 m 的记录。
关键词: 隧道; 地下立交; 大跨; 连拱; 小净距

Study on Construction and Design of Underground Interchange
Li Yong, Li Xiaochun, Hu Xuebing
Abstract: Wanshishan underground interchange in Phase I of Jichang Road Project in Xiamen city is the first
large underground interchange constructed by cover and cut method in China. It has a variety of structure
patterns and its construction procedure plicated. The whole interchange almost covers all the architecture,
structure and construction patterns of mountain tunnels, e. g. from the horizontal crossing structure to vertical
crossing structure, from the large span tunnel structure to the asymmetric twin tunnel and the small interval
tunnel, from the ordinary tunnel excavation to the innovation of the existed tunnels. The project sets the records
of 25. 8 m in the excavation span for the single tunnel and 1. 42 m in the thickness of inter space rock for the
small interval tunnel.
Key words: tunnel; undergr
