Effect of water oscillation inside lining cracks on interior pressure characteristics: Two high-speed trains intersect in a tunnel

Key Points

• Interior pressure characteristics are significantly affected by water oscillation during train intersections, creating unique dynamics in tunnel environments.
• Measurements showed fluctuations in interior pressure, specifically noting changes of up to 15% during high-speed train passage in constrained tunnel spaces.
• Observational analysis under controlled conditions simulating high-speed train interactions within tunnels highlights the complexity of pressure dynamics.
• These findings suggest that understanding water interaction is critical for improving tunnel design and ensuring structural safety.
