摘　　要：小间距并行盾构隧道施工相互作用明显,隧道间距是控制性因素。针对目前缺乏可靠的计算分析方法,设计及施工经验尚不成熟的现状,文章将盾构隧道工程中的经典结构设计方法——修正惯用法与增量法相融合,提出了反映小间距盾构隧道施工相互作用全过程的计算方法,该方法成功应用于依托工程并得到了验证,可作为小间距、长距离盾构隧道的一般设计方法。The interaction between two parallel shield tunnels with small spacing is obvious in construction, and the space between two tunnels is a controlling factor. Considering the lack of reliable computation and analysis meth- ods and inexperience regarding the design and construction of shield tunnels with small spacing, a calculation meth- od is presented to describe the whole process of construction interactions between two shield tunnels with small spacing based on a combination of the modified routine method and the incremental method, which are the typical structure design methods used in shield tunnels. As the presented method has been successfully applied in practice, it can be used as a general design method for shield tunnels with small spacing and long distances.
