摘　　要：盾构机在城市地铁建设中得到了广泛的应用，但在盾构掘进过程中会引起地层损失，过大的地层损失，可导致较大的地面沉降，对地面建筑物、地下管线等设施产生不利影响甚至会导致破坏，引起较大的经济损失。为此，本文以实际工程为例，对盾构掘进过程中引起的建筑物、地下管线位移以及引起的地下水位进行了监测，得到了规律性的结论。Nowadays, Shield machines are used widely in metro construction all over the world. However, the ground loss may occur during shield tunneling, too much ground loss may cause the great ground surface settlement. That will cause damage of the buildings and buried pipelines. For the sake of diminishing the accident due to shield tunneling, the supervising about the deformation of the buildings, buried pipelines and the aherafion of ground water table was carried out. Based on the supervised results, the laws of impact of shield tunneling on ambient environment are also obtained.
