摘　　要：盾构法是一种常用于城市地铁、交通隧道等工程中的暗挖隧道施工方法,具有机械化程度高、施工效率快、对周围环境影响小等优点。在重叠隧道盾构施工下穿铁路营业线时,由于施工空间狭小、施工要求严格、风险系数较大等因素,需要克服各种技术难题。基于此,本篇文章对重叠隧道盾构施工下穿铁路营业线施工技术进行研究,以供参考。Shield tunneling is a commonly used method for underground tunnel construction in urban subways,transportation tunnels,and other engineering projects.It has the advantages of high mechanization,fast construction efficiency,and minimal impact on the surrounding environment.When crossing railway service lines under overlapping tunnel shield tunneling construction,various technical difficulties need to be overcome due to factors such as limited construction space,strict construction requirements,and high risk factors.Based on this,this article conducts research on the construction technology of overlapping tunnel shield tunneling under railway operating lines for reference.
