摘　　要：浅埋暗挖隧道在施工过程中不可避免地对地层产生扰动,以长春火车站站场地下通道的浅埋暗挖法施工为例,通过采取预加固和强支护施工措施,并对通道开挖过程中的沉降进行严密的监测,严格控制沉降值,有效保证了通道施工的安全。从沉降控制基准值的确定、监控量测系统设计、沉降控制措施等方面论述了该隧道施工的关键点。通道的开挖支护设计与施工监测方案对相似工程具有一定的借鉴性。The construction of shallow tunnel excavation may induce disturbance of the surface ground inevitably. In the under- pass construction of Changchun Railway Station square, we have taken the measures such as pre - reinforcement and strong sup- port, intensifying monitoring to ensure the construction safety. We discuss the key points for the underpass construction, inclu- ding settlement control standard, monitoring system design, settlement control measures. The construction, monitoring and support design have the certain reference value for similar projects.
