摘　　要：鉴于传统中墙连拱隧道在结构受力性能、防排水效果等方面的缺陷,认为复合式曲中墙为深埋软弱煤系地层下双连拱隧道理想的中墙结构形式。另外,该结构施工过程中隧道衬砌台车和模板利用率高,能简化施工工序,可大大加快施工进度,节约成本。对江西向(塘)至福建莆(田)准高速铁路戴云山隧道连拱段的设计进行介绍,以期为今后类似工程的设计提供经验。In view of the deficiency of structural mechanical behavior and drainage work in traditional middle wall multi-arch tunnel,the article considers the composite curved middle wall as the ideal middle wall pattern.In addition,the high use factor of tunnel lining machine and template can simplify the construction procedure,reduce cost and speed up construction.Therefore the design of Daiyunshan multi-arch Tunnel in Jiang XI Xiang Tang to Fu Jian Pu Tian sub-high speed railway is introduced as a reference for similar projects in the future.
