摘要
长跨度工程中,传统的水准测量实现高精度的高程传递比较麻烦,对此,通过布设一定密度的GPS水准网,利用GPS水准拟合似大地水准面,快速便捷地实现GPS高到高精度水准高的转换,提高了工作效率,大幅节约了生产成本。该文通过具体的算例和计算方法,验证这种思想和方法的可行性。
To achieve the high-precision elevation by the traditional measurement of leveling in long span projects is too much troublesome to transfer , and through the deployment of appropriate GPS-leveling network, with fitting quasi-geoid using the GPS leveling, it can quickly and easily achieve the eonvertion of GPS elevation to leveling elevation, improve efficiency, and greatly save production costs. In this paper, by the specific examples and calculation methods, it verifies the feasibility of the ideas and methods.
