摘　　要：上海轨道交通2号线、10号线区间隧道以及仙霞西路道路隧道3项盾构隧道工程同时在虹桥机场飞行区实施下穿施工建设。其中10号线从运营中的机场跑道下方穿过,为国内首例在不停航条件下,在跑道下进行施工的盾构法隧道。通过精心设计、施工和监测,3条隧道穿越引起的地表沉降均控制在允许范围内,未对机场跑道及其他飞行区设施产生不良影响。The running tunnels of Shanghai Rail Transit Line 2 and Line 10,and West Xian Xia Road Tunnel all have shielded through the flight zone of the Hongqiao Airport in the same time.Among the three projects,the running tunnel of Shanghai Rail Transit Line 10 passes underneath the operating runway.It is domestically the first case that the shield tunnel has been constructed beneath the runway while no flights stopped.Through careful design,construction and monitoring,the ground settlement resulting from the three tunnels' construction was controlled within the allowable range,causing no negative impacts on the runways and the other facilities in the flight zone.
