摘要
针对岩溶地区的地形地质条件 ,结合防洪工程的实际需要 ,采用 GPS定位技术建立工程控制网 ,该网体现了 GPS测量的高效率、高精度及低成本等特点 ,为工程的总体布局及骨干工程的贯通提供了可靠的控制。
A control network is set up by using GPS technology according to the topographical and geologic condition in the karst area and practical requirement of the flood control works. The network has many merits of the GPS survey, such as high efficiency, high precision and low cost. It offers reliable control for the overall layout of the works and the completion of the main project.
