Abstract This study examines the effectiveness of Pressure Relief Ducts (PRDs) in mitigating pressure fluctuations within single-track parallel tunnels of undersea railways during high-speed train operations. Computational fluid dynamics analysis was conducted under five conditions: without PRDs and with PRDs installed at intervals of 250m, 500m, 750m, and 1,000m. The analysis evaluated internal train travel within the tunnel and calculated both internal and external pressure fluctuations of the train. Safety standards were applied to assess cabin pressure fluctuations. Results revealed a significant reduction of approximately 30% in external cabin pressure fluctuations with PRD application, meeting safety More >
