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。
In this paper, a three-dimensional finite element numerical calculation method is used to analyze the space stress of the connecting section between a multi-arch tunnel and a man-made cave cavern, and the impact of civil air defense tunnel excavation on the structure and the middle wall of a tunnel is discussed emphatically. The calculation results provide a theoretical basis for the design and construction of the tunnel, and also provide reference for the design of other similar structures.
