摘　　要：垂直度控制和标高控制是确保高层和超高层建筑施工质量的关键,传统的高层或超高层建筑施工垂直度控制和标高控制方法存在着工作过程繁琐、效率低、精度难尽人意等若干问题。为克服传统方法的缺陷,提出利用GPS技术进行高层或超高层建筑施工垂直度与标高控制的思路。三维测控采用GPS静态测量技术,测绘基准系统采用基于WGS-84椭球的高斯平面直角坐标系统和GPS大地高系统,建筑施工的垂直度控制精度优于1/300000、高程控制精度优于1/70000,给出了应用实例和工作过程。Verticality and elevation control is crucial to the construction quality of high-rise and super high-rise buildings. But the traditional controlling method is too complicated, too inefficient and difficult to ensure the precision. To overcome these shortcomings, a new idea by GPS technique is put forward. GPS static survey technique is used to the three-dimensional control of building construction, while its survey bench mark system employs Gauss plane rectangular coordinate system and GPS height system based on WGS-84 ellipsoid. Its vertical control precision is higher than 1/300 000, and elevation control precision higher than 1/70 000. An application case and its operation process are presented.
