To avoid excessive settlements caused by shield tunnelling, a systematic instrumentation is planned to monitor ground behavior during the excavation by slurry shield and to analyze the influence of construction factors on the ground movements. It is found that the ground settlements are as follows, (1) Settlement before cuttng face pass through, (2) Settlement when the shield machine passing through, (3) Settlement after the tail passed away. This paper presents settlement when the shield machine passing through is found to be related to the pose of the shield machine.
