摘　　要：中隔墙是实现隧道单洞双线布置形式的关键构件,当前研究集中于中隔墙的施工技术、受力性能,对其设计方案关注较少。本文基于上海市市域机场联络线预制中隔墙结构,对其设计方案进行了研究,以便减小冲击荷载对中隔墙产生的撞击力,在施工以及运营过程中应确保顶部节点的可靠性,避免出现顶部节点失效的情况。The middle partition wall is the key component to realize the single-hole and double-line layout of the tunnel,and the current research focuses on the construction technology and mechanical performance of the middle partition wall,and pays little attention to its design scheme.In this paper,based on the prefabricated partition wall structure of Shanghai Municipal Airport Liaison Line,the design scheme is studied,so as to reduce the impact force of impact load on the middle partition wall,and ensure the reliability of the top node in the construction and operation process,so as to avoid the failure of the top node.
