Zusammenfassung:This study concerns the evaluation on the discharge of inundating water flowed over a straight stair to underground space. First of all, survey at the entrances to the underground mall in JR Hakata Station is executed. Secondly, hydraulic experiments are carried out using a model of a straight stair. The obtained results are able to propose an empirical formula for evaluating the discharge to underground space. In particular, it is realized that the straight stair setting a footstep on the ground level's entrance has an effect on the mitigation of inundation flow in underground space.
