SUPPRESSION METHOD FOR TUNNEL INSIDE TEMPERATURE, PRESSURE, SHOCK WAVES OF MAGNETIC LEVITATION TYPE RAILWAY AND ITS STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a suppression method for tunnel inside temperature, an abnormal pressure, and shock waves of a magnetic levitation type railway and its structure.;SOLUTION: A shaft 14 or an inclined shaft is constructed at a position near the highest point in a tunnel, in a long and large tunnel for a magnetic levitation railway having a chevron-shaped longitudinal section with a high central part to generate a rising air current from both entrances to the shaft (inclined shaft). In this way, temperature increase in the tunnel can be prevented.;COPYRIGHT: (C)2003,JPO
