It is necessary to study how vibration generates and
propagates during shield construction process, so that the harm of vibration to
the adjacent buildings can be reduced. Based on the relevant research in China
and abroad, the generating sources of vibration, vibration characteristics, and
propagation law during shield construction process are analyzed, and insitu
monitoring and numerical simulation research for the vibration response of
adjacent buildings during shield construction process are discussed. Then the
existing vibration isolation and damping measures are summarized from three
aspects, namely vibration source control, vibration propagation path control,
and vibration object protection. Finally, the shortcomings of the existing
research are pointed out, and the suggestions for further research on vibration
response and vibration control during shield construction process are proposed.
The main conclusions are as follows: (1) The vibration in construction is
mainly caused by shield cutter for cutting soil. (2) The properties of soil
around the tunnel are the main factor affecting vibration propagation. (3) When
the shield travels near the adjacent buildings, measures like reducing shield
speed, controlling propulsion force, and cutting torque of the cutter are
effective to reduce the impact of tunnel construction vibration.
