洋山四期码头水工结构设计要点

洋山四期工程为全自动化集装箱港区,装卸桥荷载超出常规。码头水工结构的设计需要适应超常规的荷载和自动化工艺,特别是根据自动化装卸工艺要求,码头面层特定区域不能含有金属,以免干扰磁钉信号。针对四期工程设计条件论证码头结构形式和桩基方案,并结合工艺特点对码头主要构件设计进行创新。通过论证认为,码头适宜采用高桩梁板式结构,桩基根据覆盖层的变化分为打入桩和嵌岩桩,同时为适应超出常规的装卸桥荷载和全自动化装卸工艺,轨道梁采用深梁理论进行设计,码头面层设计中首次采用纤维增强复合材料。

Key points in design of hydraulic structure of Yangshan phase IV wharf project

The Yangshan phase IV project is a fully automatic container port,the crane load of which is beyond the conventional one.The design of hydraulic structures of wharf need to adapt to the super-conventional load and automation technology.Especially,according to the requirements of the automatic loading and unloading process,some specific areas of the wharf surface can not contain metal,so as not to interfere with the magnetic nail signal.According to the design conditions of phase IV project,the paper demonstrates the structure type and pile foundation scheme.Combining with the loading and unloading process characteristics,the innovative design of the main components of the wharf is carried out.It is proved that the wharf is suitable for the high-piled beam-slab structure,and according to the change of the covering layer,the pile foundation is divided into the driven pile and the pile embedded in rock.To adapt to the crane load and automatic loading and unloading process which are beyond the conventional ones, the track beam is designed according to the theory of deep beam,and fiber reinforced composite materials is used for the first time in the design of wharf surface layer.
