摘　　要：与以往不同,在今后的输电线路勘测中,需要获取塔位的绝对坐标会成为一种常态。按一定的距离间隔对线路上部分塔位进行联测来获取所有塔位的坐标是一种经济适用的技术方案。文章依据线路终勘的技术要求与工作特点,通过理论分析与实验相结合,推导出在较发达地区,联测点间隔应小于7km,在欠发达地区联测点间隔应小于13.7km。With the former dissimilarity, it will become a kind of normal which we need obtain the tower coordinate value in the circuit survey in the aftertime. It should be a kind of technique project on economical and applicable, which we can obtain all towers coordinate by connection measure part towers each certain distance. According to the technique request and the work characteristicses in the circuit eventually survey , combining together through the theories analysis and experiments, this article deduce that it should be small in 7, 000 meters between the connection measure points at the more flourishing region, and it should be small in 13,700 at the owe flourishing region.
