NEW AIR SHAFT DESIGN FOR RAILROAD TUNNELS

An outline of the various methods for reducing pressure fluctuations is given. These range from simple non-aerodynamic methods to complex proposals involving the optimum positioning of airshafts. The latter case leads to a new airshaft design which overcomes some of the problems caused by long airshafts of conventional design. The description has been concentrated on the case of long shafts, that is shafts which exceed about 5% of the tunnel length.
