GPS技术在高层建筑施工三维测控中的应用

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,为了克服传统法的缺陷,提出了利用GPS技术进行高层或超高层建筑施工垂直度与标高控制的新思路,高层或超高层建筑施工垂直度与标高的GPS控制摆脱了传统方法对地面控制点的过度依赖,实现了对施工垂直度与标高的快速、高效、高精度控制,确保了施工质量。结合工程实例叙述了利用GPS技术控制高层或超高层建筑施工垂直度与标高的工作过程。

Application of GPS Technique in Three-dimensional Control of Tall Building Construction

Vertical control and elevation control are the key to the tall or the super tall building construction.Traditional way of vertical control and elevation control of the tall or the super tall building construction has many shortcomings,such as overelaborate in working process,inefficient,lower in precision,etc.In order to resolve this shortcomings,a new thinking to control vertical and elevation of the tall or the super tall building construction by GPS technique has been put forward.GPS three-dimensional control technique of the tall or the super tall building construction cast off the yoke of traditional ground control points.It can control the vertical and elevation of the tall or the super tall building construction with high-speed,high-efficiency and high-precision.And it can guarantee construction quality.The working process of GPS three-dimensional control technique of the tall or the super tall building construction has been given by one example.
