Purpose The paper aims to clarify the operation rationality of high speed trains (HSTs) under tunnel condition with 400 km/h through representative aerodynamic factors including running drag, eardrum comfort, carriages noise, loads on ancillary facilities and HST, micro-pressure waves, then put forward engineering suggestions for higher based analysis. Design/methodology/approach Based field measurement data CR400AF-C CR400BF-J operation, correlations between each indicators HST were...
After decades of research in the field high-speed railway technique, technology running trains at velocity level 350 km/h gradually become mature. It is great importance to capture variation regular aerodynamic parameters situation that train runs a higher speed level. The present paper motivated by this knowledge gap, both tests and numerical simulations were conducted help illustrate basic characteristic transient pressure loads, micro-pressure wave, as well wave propagation inside tunnel...
With the implementation of regional coordinated development strategy, traffic flow has grown explosively. The construction a larger tunnel section becomes an effective way to solve highway network’s insufficient transport capability problem. Currently, there is little research on factors influencing and methods calculating loose pressure in surrounding rock mass for tunnels with super-large cross-sections. Based Bifurcation Tunnel, which one sign projects past five years, this paper...
The transient temperature response is of great importance for evaluating the thermal capacity ground heat exchangers (GHE). Based on composition line source theory and superposition principle, we have developed a novel analytical model in Laplace space calculating response. In comparison to existing models, this proposed can account fluid storage effect rate difference between two legs single U-tube. With aid model, conduct thorough sensitivity analysis investigate effects different...
Summary Preventing smoke back‐layering in longitudinal‐ventilated tunnels is an important topic handling with fires safety issues. Previous studies focused on the critical velocity, while only very few of them paid attention to how realize this parameter, that is, a state, overcome resistance tunnel and fire source airflow, required driving force provided by ventilation equipment installed tunnel. This study addressed problem situation where coupling effect blockage throttling was...
