Overview

Full-scale testing reveals structural stability under asymmetric loading in underground stations, suggesting precast methods are viable.

Key Points

  • Structural stability was verified, meeting design requirements with a significant safety margin.
  • The maximum tensile and compressive stresses were below yield stress, ensuring safety under load.
  • Full-scale tests showed a 13.67% increase in maximum deflection compared to numerical simulation values.
  • Reliability of the analytical methods was confirmed, although testing was limited to one-sided loading.
