摘　　要：随着地铁轨道交通的迅猛发展,越来越多的换乘节点工程必然出现,也将出现更多的枢纽换乘车站施工技术问题。在全暗挖十字换乘地铁车站交叉节点施工方案设计上,就存在多种方案可以选择,为了达到控制地表沉降,确保路面行人及行车安全的目的,本文以长春地铁1号线解放大路站交叉节点施工方案比选为例,从沉降量大小、关键节点应力分布和土体塑性区变化等主要因素进行详细分析,得出了从衬砌端破马头门施工连接段的最优方案,为今后换乘车站及其关键节点施工技术提供技术和经验的指导,同时指导类似的工程设计及施工,促进地铁轨道交通施工技术的快速发展。With the rapid development of Metro Rail Transit ,more and more inevitable transfer station project will appear and with lots of problems of the construction technology of transfer hub station .There are lots of schemes to choose about the cross nodes construction of cross interchange metro station by shallow excavation .In order to control the settlement and make sure the safety of pedestrians and driving ,the paper takes Metro Line 1 Liberation Road Station in Changchun as the example ,ana-lyzes the settlement ,the stress distribution of key nodes ,the variety of plastic zone of soil and other factors ,and gets the opti-mal solution of constructing connection segment by breaking the horsehead from the lining ,which provides the technology and experience for the following construction on interchange stations and the key nodes and guides the similar projects ,promoting the development of the railway traffic technology .
