摘　　要：主体通关大厅为横琴口岸的主要通关建筑,建筑功能复杂,空间划分要求特殊,对结构体系选型带来一些影响。论文通过对主体西段、主体东段的结构体系进行分析比较,阐述了两种结构体系各自的适用性,分析了缓黏结预应力框架梁在本项目中的应用。分析了主体东段与周边4栋建筑通过高位连廊连接形成连体结构在中大震下的相互影响,钢连廊通过铅芯橡胶支座可有效释放不协调变形的不利影响。对于支承连廊的牛腿设计进行了节点受力分析,采取了防腐防碰撞及防跌落的构造措施。桩基设计结合横琴深厚淤泥土层特点采用一柱一桩的大直径超长灌注桩。As the main customs clearance building of Hengqin Port,the main customs clearance hall has complex building functions and special space division requirements,which has some influence on the structural options.Through the analysis and comparison of the structural systems of the west section of the main body and the east section of the main body.The applicability of the two kinds of structural systems is described.The application of slow-bonded prestressed frame beams in this project is expounded.The east section of the main body and the four surrounding buildings are connected by high-level corridors to form a conjoined structure.The mutual influence of the conjoined structure under medium and large earthquakes is analyzed.Steel gallery through lead rubber bearing can effectively release the adverse effects of incompatible deformation.The joint force analysis of the design of the bull leg supporting the corridor is carried out,and the structural measures of anti-corrosion,anti-collision and anti-falling are taken.In combination with the characteristics of deep silt soil layer in Hengqin,the pile foundation design adopts a large-diameter and long-length cast-in pile with one column.
