摘　　要：盾构法施工凭借效率高、扰动小等优势已然成为隧道工程建设中常用的手段。不同工程的地质水文环境不尽相同,盾构装备能否适应地质水文环境是决定施工能否高效、安全开展的关键因素,这在复合地层大直径隧道施工时更为明显。依托广州南站联络线隧道工程,识别出工程区间存在盾构选型适应性、刀盘刀具磨损、大直径浅埋盾构掘进控制三种重大风险,基于此针对盾构选型、刀盘刀具、推进驱动系统进行适应性选型设计。实践证明,经针对性设计后的盾构装备在此区间地层适应性优良,能够提升施工效率,保障施工安全。Shield construction has become a common method in tunnel engineering construction due to its advantages of high efficiency and small disturbance.The geological and hydrological environment of different projects is different.Whether the shield equipment can adapt to the geological and hydrological environment is the key factor to determine whether the construction can be carried out efficiently and safely,which is more obvious in the construction of large-diame-ter tunnels in composite strata.Based on the liaison line tunnel project of Guangzhou South Railway Station,three major risks of shield selection adaptability,cutterhead tool wear and large-diameter shallow-buried shield tunneling contro are i-dentified in the project interval,so as to carry out adaptive selection design for shield selection,cutterhead tool and pro-pulsion drive system.The shield equipment after targeted design has excellent adaptability in this interval,which can im-prove construction efficiency and ensure construction safety.
