DEVELOPMENT AND TEST OF SIMPLIFIED METHODS TO PREDICT SUBWAY AIR PRESSURE TRANSIENTS
This report is one of many reports leading to final product, a subway environmental design handbook. Simplified models are introduced to predict subway air pressure transients. The models deal with pressure changes due to portal entry, post portal entry, vent passage, portal exit and passing trains. Predictions yielded by the models are compared to full-scale field test data gathered at BART. It was concluded that the models are sufficient to identify pressure transient problem areas, as well as solutions in the early stages of subway system design.
