摘　　要：＂近接施工＂工程问题一直以来都是地下工程关注的热点.在许多地铁隧道近接隧道施工中,上、下重叠隧道是城市地下隧道中最基本和常见的近接隧道类型.本文以深圳地铁9号线孖岭站~银湖站区间隧道上跨深圳地铁9号线停车场入场线隧道近接隧道施工的控制技术研究项目为契机,运用Midas-GTS进行三维分析,着重于研究不同施工工序对重叠隧道近接施工力学行为及对地表沉降的影响,进而指导设计和施工.The issue of ＂Approaching construction＂ is a major concern for underground engineering. In many cases, as approaching construction applies, overlapped tunnel is the most basic and common type of urban metro. Making control technology research project of Shenzhen subway NO.9 line Maling-Yinhu tunnel overlapped with Entrance tunnel of parking lot of Shenzhen subway No. 9 line as an example, this article applies Midas-GTS for 3 dimensional analysis and guides the design and construction, by focusing on effects on mechanical behavior of approaching construction of overlapped tunnels and the ground surface settlement resulted from different construction processes.
