Title:
MULTI-WAVEFIELD SEISMIC DETECTION METHOD AND SYSTEM EMPLOYING CONSTRUCTION NOISE OF SHIELD TUNNELING MACHINE
Document Type and Number:
WIPO Patent Application WO/2021/227236
Kind Code:
A1
Abstract:
A multi-wavefield seismic detection method and system employing construction noise of a shield tunneling machine. Noise information generated by a shield tunneling machine during construction work is used as a seismic source to obtain multi-wavefield seismic information, such as body waves and surface waves which are formed during propagation of excited seismic waves in a stratum. Stratum velocity modeling along a tunnel is carried out by means of joint inversion, and offset imaging is performed using information such as reflected waves, thereby achieving accurate detection of geological conditions ahead of a tunnel face of a tunnel under shield tunneling construction.
