As more megacities emerge owing to urbanization and industrialization, the subway has
become the main public transportation mode worldwide, providing punctuality and …

Metro systems have been in use for over 150 years, and new metro lines are still being
constructed, either as new metro systems or as expansions of existing metro networks. In …

This study was based on computational fluid dynamics (CFD) and field measurement
verification. First, we researched and analyzed the main ventilation system, when closed or …

To decrease the high concentration dust in tunnels with a long-duct forced and short-duct
exhaust ventilation system, airflow and dust field migration behaviours, when different …

In order to avoid pneumoconiosis and other hazards caused by excessive concentrations of
dust in construction tunnels, this paper applies CFD numerical simulation, in combination …

With the flourishing development of the subway construction, it becomes increasingly urgent
to improve the subway tunnel environment and reduce the energy consumption of the tunnel …

Transient pressure changes induced by trains passing through tunnels have a significant
influence on the structural safety of tunnels. A verified numerical method was employed in …

The piston effect due to train movement in a subway system significantly affects the
ventilation system in the stations and connecting tunnels. In this study the train movement in …

Super-long metro tunnels, which allow two trains to simultaneously drive in the same tunnel
direction, have become increasingly important in urban areas where construction is …

The pressure transient on a platform screen door (PSD) is crucial for its structural safety and
proper operation. This study experimentally investigated the train-induced pressure on the …
