説明

<p> Since the Great East Japan Earthquake, the mound-type tsunami evacuation facility has become crucial because evacuees to this type of facility survived the disaster caused by the tsunami. Based on the examined results in Fukuroi City, Shizuoka Prefecture, a method for designing mound-type tsunami evacuation facility has been developed. In this design method, the inundation depth estimated from the tsunami simulation was applied to examine the crest height and the stability of the facility. A high-resolution analysis based on the tsunami simulation was implemented to model the surrounding houses as terrain. We believe that runup will rise in the tsunami evacuation facility, judging from the positional relationship between the tsunami evacuation facility and the surrounding houses, which cause flow inhibition. This paper reports the examination of the separation distance between tsunami evacuation facility and the surrounding houses.</p>
