    Three-dimensional numerical simulation and wave field analysis of seismic-while-digging model with faults by Shuai XU, Guangzhong JI, Yakuan GAO, Wenjie JIAO, Dixiu HE

    Published 2025-06-01
    “…According to the characteristics of the seismic-while-digging source, the stress mode of the cutting head of the boring machine is studied, and the force analysis is carried out. The real data of the seismic source is loaded into the three-dimensional fault model for forward simulation, and the correlation conclusions of radial, transverse and vertical components are obtained( the radial, transverse and vertical components are collectively referred to as x, y and z components); on the basis of the force analysis of source of the seismic-while-digging, a Ricker wavelet point source is loaded on each point of force, and a single shot source is simulated to verify the effectiveness of cross-correlation processing of the following excavation seismic records. …”
