GPS大地高高差用于工程土方量计算的探讨

Application of GPS Geodetic Height Difference in Engineering Earthwork Calculation

介绍了直接利用GPS大地高高差计算某工程土方量的方法,并将所得结果与用全站仪三角高程测量方法测算的结果进行比较,证明在一定范围内直接将GPS大地高高差应用于工程土方量的测算不仅是可行的,而且可以达到很高的精度。

This paper introduced the method of directly using GPS geodetic height difference to calculate engineering earthwork at first. And then, the paper made a comparison between the calculation result obtained by GPS geodetic height difference and trigonal height measurement using total station. The results show that it is feasible to directly use GPS geodetic height difference to calculate engineering earthwork with high precision.
