PARTIALLY FLOATING MARINE PLATFORM FOR OFFSHORE WIND-POWER, BRIDGES AND MARINE BUILDINGS, AND CONSTRUCTION METHOD

摘要

Disclosed are a partially floating marine platform for offshore wind-power, bridges and marine buildings and a construction method. The platform comprises at least one buoyancy tube disposed vertically and with a tapered base, the buoyancy tube being a hollow column; to the base thereof are added small-bore bored piles or small-bore driven piles fixed to the bedrock or the bearing stratum of the seabed and, together with the soil layer of the tapered base of the buoyancy tube, capable of supporting external forces. The buoyancy force of the buoyancy tube can counterbalance the weight of part of the building and transform a tilting load borne by the entire foundation into loads that vertically press down and pull up on a single buoyancy tube foundation, by means of a spatial structure of multiple buoyancy tubes. The platform is able to be cast in-situ or prefabricated onshore, assembled at coastal margins, and then towed to the installation location. The marine platform can be used in marine environments with more than 5 metres of soil layer on the sea bed and with a water depth of approximately 5 to 50 metres.
