The invention relates to an offshore large steel-concrete combined floating type semi-submersible platform structure which can be used for construction of offshore large infrastructures such as offshore airports, offshore bases and even offshore artificial islands. The structure is formed by splicing a plurality of single bodies, and the adjacent single bodies are connected with each other. Each single body is of a steel-concrete combined semi-submersible type structure and comprises a floating body submerged underwater, a stand column supported on the floating body and an upper deck. The floating body is composed of a steel-concrete combined plate, the stand columns are multi-cavity steel pipe concrete columns, and the upper deck is a truss type steel-concrete combined deck. The stand column and the floating body are both of a hollow structure and provided with a plurality of cabins. The advantages of the steel and the concrete are fully utilized, the advantages of being high in bearing capacity, high in strength and rigidity, resistant to explosion, easy to construct and the like are achieved, and wide application prospects are achieved in offshore large floating platforms.
本发明涉及一种海上大型钢‑混凝土组合浮式半潜平台结构,可用于海上机场、海上基地甚至海上人工岛等大型海洋基础设施建设。结构由多个单体拼接而成,相邻的单体之间相互连接。每个单体均为钢‑混凝土组合半潜式结构,包括潜入水下的浮体、支撑于浮体上的立柱和上部甲板。浮体由钢‑混凝土组合板构成,立柱为多腔钢管混凝土柱,上部甲板为桁架式钢‑混凝土组合甲板。立柱和浮体均为中空结构,并设置多个舱室。本发明充分利用钢与混凝土的优势,具有承载力高、强度刚度大、抗爆、易于施工等优点,在海上大型浮式平台中具有广阔的应用前景。
