    摘要:

    超高层建筑在施工放样工作中分析轴线控制点平面坐标的精度。对于倾斜超高层建筑高精度的控制点坐标传递,采用全站仪与激光准直仪相结合,在楼层上多次分段转折投测,逐段接力将控制点坐标传递到顶层控制点。在各楼层控制点上用全站仪测量出控制点到轴线控制点之间的边长,计算轴线控制点的坐标,并对其坐标精度进行分析。获得超高层建筑施工放样从控制点到轴线控制点多次分段传递平面坐标的集成方法和采用先进测量设备提高轴线控制点坐标的精度集成方法。为选择不同精度的全站仪和激光准直仪快速、准确分析控制点的误差,为优化施工放样方案、指导超

    Abstract:

    When staking out super highrise building construction, it is important to analyze the horizontal coordinate precision of the control point of the axis. For coordinate transfer of control points of oblique super highrise buildings with high accuracy and precision, methods combining the electronic tachometer with laser aligner were adopted. The measurement sections were transited by sections many times on the floors. The coordinates of control points of lower floors gradually were transferred to the top floor by relays. We then could use the electronic tachometer to measure the linear distance between the control points of each floor and the control point of the axis, calculate the coordinates of the axis control point, and analyze the precision of the coordinates. Thus, integrated methods of transferring horizontal coordinates of super highrise buildings setting out of axis repeatedly can be taken from the control points to the monitoring points section by section. The precision integrated methods improve the coordinates of the control point of the axis by adopting advanced measurement equipment. We recommend choosing an electronic tachometer with different precision and a laser aligner to analyze the control point error quickly and accurately, provide a complete and systematic method for optimizing the stakingout scheme in construction, and guide the stakingout work and deformation monitoring work of super highrise buildings or oblique super highrise building construction.
