摘　　要：横琴口岸设有两座交通平台,采用了大跨度型钢混凝土框架结构。交通平台作为口岸建筑消防扑救场地,抗震设计时基于车辆实际布置等因素合理确定活荷载质量。交通平台与城市桥梁连接处设有共用柱墩,其抗震性能目标为中震弹性、大震不屈服;城市桥梁的支承节点、不规则柱网处梁柱节点等特殊部位采取了加强措施;进行温度作用分析并采取了超长结构技术措施。Hengqin port is equipped with two transportation platforms with large span steel concrete frame structure.As the fire fighting site,the traffic platform can reasonably determine the living load quality based on the actual layout of vehicles.The common pier is provided at the junction between the transportation platform and the urban bridge,and the seismic performance targets are midshock elasticity and the failure;the support joints and irregular column nodes of the urban bridge are strengthened;the temperature action analysis and the technical measures of ultra-long structure are taken.

关 键 词：结构设计 超长结构 温度作用 交通平台
