THE EFFECT OF SUBWAY MODEL IMPROVEMENT ON THE INUNDATION CHARACTERISTICS OF SUBWAY NETWORK

Abstract

 There is an increasing possibility that rainfall patterns will change due to the effects of climate change associated with global warming. In addition, the use of underground spaces such as underground mall and subway is progressing in Osaka, and the subway network is expanding. In this paper, subway model considering the detailed shape of the tunnel based on the construction records shown in the published books is built, and conducted pluvial flood simulation.

 The results show that the detailed tunnel shape affects the propagation of flood water. In addition, the subway stations at high risk for flood can be pointed out by the improving subway model.
