适用超大型门式起重机出运工艺的新型海洋重工码头设计创新

打造世界第一的2台11 000 t轨道式门式起重机,超大型海洋重工产品直接吊运下水、对接、合拢,是海洋重工产品制造工艺、出运工艺的重大突破。为满足工艺设备轨道基础的超大荷载和严格的变形使用要求,设计提出的超宽整体卸荷式钢桩组合板桩码头结构方案,结构新颖。而码头结构受力复杂,尚无成熟的计算方法,其受力模型和计算方法值得进一步研究和探讨。

Design innovation on new offshore platform terminal with applicable super gantry crane handling technology

It is a great breakthrough in ocean heavy industry that the manufacturing of the first rail-mounted 2 × 11 000 ton gantry crane in the world, as well as direct unloading, split and assembling for super-heavy industry products. To meet requirements on the rail foundation with extreme heavy loading and strict deformation criteria, a new structure type of composited steel pipe pile and sheet pile with extreme wide integrated relieving slab is developed. No well developed calculation method can be referred at the moment due to its structural complexity. The bearing mechanism and calculation method remain the topics for further research.
