Multi-wave field earthquake detection method based on the construction noise of a shield machine and associated system

摘要

The present disclosure provides a multi-wave field earthquake detection method based on shield machine construction noise and an associated system. In the present disclosure, using the information of noise generated by a shield machine when operating as an earthquake focus, multi-wave field seismic information of body waves and surface waves generated by the generated seismic wave while propagating in the earth stratum is acquired, using a earth stratum velocity model is constructed along a tunnel by joint inversion, whereby migration, among other things based on the information of reflected waves, finally achieves precise detection of the geological condition in front of the face of the tunnel built by shield methods.
