［摘要］华源办公大厦副楼属平面不规则结构。针对地下室柱网尺寸大且地下水位高、楼盖跨度大且活荷载重、结构超长等特点，结构设计中分别采用抗浮锚杆、组合楼盖和后浇带等技术措施，以满足建筑功能要求。还对上部超长结构温度应力分析的结果和大跨度钢梁的施工方案进行了介绍，供类似工程借鉴。

Abstract:The vice-floor of Huayuan office building belongs to irregular plane structure. According to the characteristics of large column network dimension of basement and high groundwater table, large span and heavy live load of floor, and super-long structure, the technology of anti-floating anchor, composite floor and late poured band etc. were used separately in design in order to satisfy the architecture requirement. The analysis results of temperature stress of super-long structure and construction scheme of large-span steel beams were also introduced. Design points of this project could provide reference for similar projects.

Keywords:irregular plane; anti-floating; planar large opening; temperature stress
