摘要
介绍了焦作市古汉山至赵固间的铁路GPS测量控制网的布设方案及数据处理方法,分析了该控制网的实测精度,比较了各点GPS拟合高程与水准高程差值精度,对拟合高程代替水准高程的可行性进行了分析。实践证明,此次采用的短边狭带状控制网布设方法工序简单,使用方便,整体效率高。
This paper introduced the design plan and data treatment method of GPS control survey network for coal mine special railway lines from Guhanshan to Zhaogu No. 1 coal mine. In this paper,the author analyzed the measurement accuracy of the control survey network, made a comparison on the height difference accuracy between GPS fitting height and leveling height,pointed out that replacing the level height with fitting height was feasible. Application practices show that the laying out method and the measurement procedure of narrow band network with short-side is simple and easy to use, the whole efficiency is high.
