PROBLEM TO BE SOLVED: To provide a tidal wave evacuation facility of a structure endurable against a tidal wave, without enlarging a member of respective parts of a structure.SOLUTION: The tidal wave evacuation facility 1 is provided so that outside end wall parts 11 and 21 for gradually expanding an interval in the orthogonal direction to the arrival direction (x) toward the center from the tip of the structure to the respective arrival direction (x), are provided in one side end part 10 and the other side end part 20 along the arrival direction (x) of the assumed tidal wave, and inside end wall parts 12 and 22 are provided inside along its outside end wall parts 11 and 21, and are formed as a part of a wall structure for supporting weight of the structure by a double wall part composed of the outside end wall parts 11 and 21 and the inside end wall parts 12 and 22, and an outer surface of the outside end wall parts 11 and 21 is formed as a tidal wave guiding part for releasing a water flow and a drift of the tidal wave to the outside in the orthogonal direction to the arrival direction (x), and a slope (s) for tying between floors of a different height, is provided between the outside end wall parts 11 and 21 and the inside end wall parts 12 and 22. |
