Aim to improve the interpretation of seismic signals induced by TBM drilling noise by using advanced signal processing techniques.
Developed an adaptive impulse reconstruction algorithm combining CEEMDAN screening and MDD interferometry.
Utilized band-limited inversion, phase-only whitening, and a multi-reference strategy in MDD processing.
Conducted numerical experiments with a 3D elastic tunnel model and field measurements from an operating TBM tunnel.
Proposed workflow produced a more compact and coherent virtual-source gather compared to traditional methods.
Numerical experiments indicated enhanced retrieval of interpretable impulse-like responses.
Field measurements confirmed the effectiveness of the method in real tunneling conditions.
