| Abstract: | The GPS static positioning technique has been gradually taking the place of the conventional triangular survey technique and is becoming the mainstream technique for establishment of the horizontal control network for bridge construction survey. With reference to the author′s practice of bridge engineering survey over the years, the optimal design methods for the precision, datum and geometrical figure of the network are systematically analyzed and brought forward, and the methods and key techniques for the selection, layout and marking of the GPS control points, the GPS observation and data processing are described as well. |
