Overview

Numerical modeling predicts geological heterogeneities near tunnels, indicating improved construction safety.

Key Points

  • This work aims to use the grid-characteristic method for detecting geological features near tunnels.
  • Application of the grid-characteristic method for seismic wave modeling
  • Verification based on field experiments near an under-construction tunnel
  • Numerical experiments conducted for three geological scenarios
  • Demonstrated qualitative agreement with real seismograms
  • Confirmed the ability to detect geological features ahead of the tunnel face
  • Produced wave fields and probability maps of heterogeneity boundaries
