摘　　要：隔震设计近年发展较快,在房建、路桥领域已取得较多应用且效果较好,但隔震设计对于常规码头效果不明显。高桩LNG码头抗震设计要求高,尤其在强震地区,地震荷载通常起控制作用,因此较适宜采用隔震设计。参考其他行业的做法,推荐可用于高桩LNG码头的隔震设计方法,在结构设计上提出一种与装配式结构相结合的方案,具有可快速施工、可及时更换的优点,并给出高桩LNG码头隔震设计的算例。研究成果可为强震地区高桩LNG码头设计提供参考。Seismic isolation design has developed rapidly in recent year,and has been widely used in the field of civil buildings,roads and bridges with good effect,but the seismic isolation design has no obvious effect on conventional docks.For pile supported LNG pier,due to their high requirements for seismic design,the seismic load usually serve as the control function of the structure,especially in high seismic regions,so it is more suitable to adopt seismic isolation design.Referring to the practice of other industries,this paper recommends the isolation design method suitable for pile supported LNG pier.In structural design,a scheme combining with prefabricated structure is proposed,which has the advantages of rapid construction and timely replacement.The research results can provide reference for the design of pile supported LNG pier in strong earthquake area.
