| 摘 要： | 在小范围的精密工程与形变测量问题中,对测量精度的要求越来越高。随着GPS技术的日益完善,选择GPS进行工程控制测量、施工放样与变形监测已成为越来越普遍的选择。然而选择GPS进行测量必须面对大地水准面差异的问题。本文提出一种基于高差的处理方法,对该问题进行了研究。并对工程测量中相关问题进行模拟计算,得到满意的结果。

| Abstract: | In the small range precise engineering and deformation survey, more and more high precisions are required. GPS technology, along with its development, becomes common and significant in this field. But when using GPS, the problem of difference for territorial geoids is faced. This paper, based on the difference of height, gives a new method to study this problem. When this method is used in some engineering survey, the results should be satisfied. |
