摘　　要：国家会议中心工程超长,超宽,施工周期较长,测量精度标准要求高,常规测量手段难以满足要求。在施工现场布设两级控制网的测量方案,使建筑物的整体精度得到保障。超长轴线的投测采用独特的两点间恢复直线的测量方法,既满足施测精度,又提高测量效率。建筑物轴线竖向传递采用首层布设内控点,使用激光铅直仪进行传递的方法,满足细部轴线的测设精度。As the National Conference Center is a super long and super wide project with long construcnon period and high requirement of surveying precision, the ordinary surveying methods cannot meet the requirement. 2 levels of surveying control net set up on the site have ensured the integral precision of the building. The special surveying method adopted for the super long axis not only satisfied the surveying precision but also improved the surveying efficiency. As for the vertical transfer of the building axis, control points were arranged on the ground floor, and laser plumb instrument was used for the transfer, reaching the surveying precision of local axis.
