Description
Technical field
The present invention relates to field of ocean engineering, specially a kind of half dentation for inhibiting sea ice to climb and accumulate along slope
Half arc convex body.
Background technique
Under the effect of the ambient driving forces such as wind, stream, sea ice climbs and accumulates along the slope of bevel structure, if without phase
The Disaster Prevention Measures answered, the climbing and accumulation of sea ice will constitute a threat to offshore platform structure, or even damage.In order to reduce tiltedly
The climbing and accumulation of sea ice in the structure of face, generally use three kinds of methods: (1) increasing the gradient on slope；(2) protrusion is set on slope
Body；(3) perhaps a clump of piles builds the ancillary measures such as jackstone around gear ice structure or works to setting gear ramparp before works.
Economically, the combined factors such as the simplification of measure and control sea ice force consider that setting raised body is most suitable.
Existing raised body structure is all one broken line protrusion of protuberance from slope, realizes the variation of the gradient, to play suppression
Make ice the effect climbed.But this simple change broken line raised body, an only two-dimensional slope surface variation, and slab in reality
Destruction is all irregular plate, is the trash ice block of 3 D stereo, does not play the role of ice-breaking especially and inhibits accumulation,
Therefore, the ability that this simple change broken line raised body inhibits ice to climb and accumulate is limited.
In view of the above drawbacks, creator of the present invention obtains the present invention by prolonged research and practice finally.
Summary of the invention
