Overview

Investigates seismic performance impacted by void defects in shield tunnels, indicating critical factors for safety management.

Key Points

  • The aim is to analyze how voids behind tunnel lining affect seismic safety performance and predict responses.
  • Analyzed causes and distribution patterns of voids in large-diameter shield tunnels.
  • Developed a three-dimensional finite element model to simulate interactions in tunnel structures.
  • Performed single-factor and multi-factor sensitivity analyses on seismic response metrics.
  • Voids increase circumferential stress, displacement, interface opening, and bolt stress in tunnels.
  • A void at the right haunch leads to a peak circumferential stress of 3.27 MPa, risking damage.
  • Sensitivity analysis indicates void location is the most significant factor affecting seismic response.
