摘要(Abstract):
在测量跨江(河、海)导线的水面垂直距离和两回线路在水面上空交跨的垂直距离时,由于大部分水面上不能设置目标,所以测量难度较大,为此介绍了现场测量的方法、精度分析和详细测量步骤。
For measurement of vertical distance over water surface and vertical distance between double-circuit crossing-river lines over water surface in crossing-river(sea) transmission,the difficulty rests in failure of target set on most of water surfaces.Hence the paper introduces filed measurement method,precision analysis and detailed measurement process.
