摘　　要：为了研究新建隧道的开挖对既有地铁结构的影响,通过对上跨地铁节点的计算得出长短桩的围护设计方案,并对围护设计方案和节点基坑开挖顺序进行数值模拟,验证了此方案的可行性,为复杂环境下新建隧道工程的顺利实施提供参考。In order to study the deformation effect,caused by the excavation disturbance of new tunnels,on the structure of existing subway,the design of long and short piles is obtained through the calculation of the upper span subway nodes.In the meantime,the numerical simulation of the retaining design,as well as the excavation sequence of node foundation pit is carried out so that the feasibility of this scheme is verified.The results of this paper can provide useful reference for the successful implementation of the tunnel construction in complex environment.
