| 摘 要： | 在输电线路施工中, 弧垂观测是架线分部工程中重要的控制项目。在大跨越线路工程导、地线弧垂观测中, 由于局部气候及档距大的影响, 弧垂观测工作与普通导、地线弧垂观测有所不同, 而且这些不同对导地线弧垂的精度有较大的影响。文章通过对工程实例观测数据的分析, 提出了消除初伸长的影响和改进测量气温方法这2 项改进措施, 从而提高弧垂观测的精度。

| Abstract: | During transmission line construction, sag observation is an important control item of stringing. Because of local weather and large span, conductor and earthing wire sag observation in large span line construction is different from that of normal lines, resulting in relatively large affects on accuracy. Tbrough analyzing of practical project data, two measures, which are initial stretch affect removal and improved temperature measurement, are introduced to improve accuracy. |
