摘　　要：文章采用三维有限元数值计算方法,对连拱隧道与人防洞室连接段进行了空间受力分析,重点探讨了人防通道开挖对隧道正洞结构及中墙产生的影响。其计算结果为隧道的设计与施工提供了理论依据,也可为其它同类结构的设计提供参考。By using the spatial FEM numerical calculating method, the forces applied on the connection between a dual - arch tunnel and a civil defense passage is analyzed, especially the influence of passage excavation on the main tunnel structure and central diaphragm. The calculating results are taken as the theoretic basis for the tunnel design and construction, as well as the reference for the design of similar structures.
