摘　　要：在南昌汉代海昏侯国遗址展示服务中心项目的结构设计中,结合建筑造型,采用了一种新型的编织环状结构体系,实现了环带大跨越的同时创造了环状体内完整的无柱空间。首先对其结构体系、传力方式、变形及内力分布进行了分析研究;随后对结构设计中的一些关键问题如楼板平面内刚度、屋面支撑的布置形式及结构施工和卸载过程进行了分析研究;最后介绍了结构施工及卸载阶段的应力和变形的监测结果。研究结果表明,该结构体系的受力机理与建筑造型结合较好,楼面的组合楼板及屋面的支撑是结构体系的关键组成部分,需要对其受力性能进行重点研究并采取相应的加强措施,制定合理的施工安装顺序和卸载方案对于结构体系的构建也起到十分重要的作用。In the structural design of exhibition service center of Nanchang Han Dynasty Haihun Kingdom heritage,according to the architecture modeling,a new weaved ring structure system is adopted.The large span of the ring is achieved and the complete column-free space inside the ring is created.Firstly,the structure system,the force mechanism,the deformation and force distributions were researched.Then some key problems in structural design,such as in-plane floor stiffness,arrangement of roof braces and structure construction and unloading process were analyzed.Finally,the monitoring results of stress and deformation during construction and unloading were introduced.The research results show that the mechanical mechanism of the structural system is well combined with the architecture modeling,the composite floor and roof braces are key components of this structural system,their mechanical performance should be researched and the corresponding strengthening measures should be taken,formulating a reasonable construction and installation sequence and unloading program also plays an important role for constructing the structural system.
