PURPOSE:To fix a structure for ice sea by a method in which a slope to break ice plates is provided on the peripheral side of the structure body of a flat form and a concaved portion into which ice pieces are packed from the upper end of the slope for applying a load to the structural body is also provided. CONSTITUTION:When ice plates 16 are formed and ice force F acts on the ice plates 16 in the winter season, the ends of the ice places 16 come into contact with the slope 5 of the marine structure body 2, is warped upwards, and broken into ice pieces 16a by the bending stress. The ice pieces 16a are pushed up to the slope 5 by coming ice plates 16 and dropped into the concaved portion 3. The structural body 2 is fixed to the seabed 12 by the weights of the body 2, the ice pieces 16a, ballast water, and an excavator equipment 19. |
