［摘要］广州新客站屋盖为大跨度空间钢结构，主要由预应力索拱和预应力索壳组成，整体稳定是结构设计的控制因素之一。在多种不利荷载组合作用下，分别研究了主站房和无站台柱雨棚屋顶钢结构的线性稳定性能，并进行了考虑几何非线性、材料非线性和初始缺陷的非线性稳定分析。结果表明，屋盖结构具有良好的整体稳定性能。

Abstract:The roof structures of New Guangzhou Railway Station are long-span spatial steel structures, and are mainly composed of prestress arch structures and prestress shell structures. The structural system is complex and the scale is very large，and the integral stability is one of the key problems of structural design. The linear stability of roof structures is studied under multiple kinds of worst load combinations, and also the nonlinear stability analysis of roof structures is conducted by considering the geometric and material nonlinear, and the initial geometric imperfection. The results show that the integral stability of the roof structures is good.

Keywords:New Guangzhou Railway Station; steel roof structure; nonlinear integral stability
