摘　　要：采用高精度GPS—RTK静态测量模式,将2台GPS基准站置于地面上的基准控制网点上,通过对GPS—RTK定位测量系统的测量,测算出楼面控制点在施工坐标系中的具体坐标。并通过全站仪来照准待放样点在楼层顶面上的具体位置,以达到精确测量和放样的目的。优点:可以消除传统方法中的累积误差,提高建筑结构垂直度;不受观测孔限制,测量和放样的精度高,操作简便,工作效率较高。此方法的扩展使用性强,可用于其他不同的施工项目中。With the use of the static measuring model of accurate GPS -RTK positioning, two fiduciM stations are fixed on the ground controlling sites to measure the concrete coordinates of the floor controlling sites in the whole construction coordinafing sys- tems. The total station is applied to acquire the set points of the layout survey on the surface of the building. The merits of thi~ method can he found in the elimination of the cumulative errors found in traditional methods and in the improvement of the vertical structures. With high precision and simple operation, this method will not be limited by the aperture and can achieve an accurate result of measuring ＆ layout survey and can be applied for a variety of other construction projects.
