摘　　要：架空线路终勘定位在一般地区常采用先定立某一耐张段的转角塔后,在依顺序定立该耐张段中直线塔的作业模式,但在黄土梁峁地区,不良地质灾害较为发育,立塔条件受限,某基直线塔无法订立时,可能造成某一耐张段无法成立。因此,若采用常规作业模式,将造成一定的返工,影响工期和造成成本增加。为解决这一问题,可在外业增加一工作组,对每基预排塔位进行遥感解译,对其中解译出的存疑塔位进行现场判定,提前进行塔位或路径的调整,再进行定位。此方法可较大程度提高了终勘定位的效率。In the general area, the working mode of the final surveying and positioning in this section is established suspension tower according to the order after had established tension tower, but the bad geological disasters are more developed in the loess ridge, When the tower is in a limited condition, a suspension tower can not be established, it may cause a certain tension section can not be established, therefore, if the use of conventional working mode, will result in a certain rework, affecting the duration and cost. In order to solve this problem, a working group can be added in the field to carry out remote sensing interpretation for each pre-arranged tower position, to decode the doubtful tower position in advance, to adjust tower position or path in advance, Positioning. This method can greatly improve the efficiency of final survey positioning.
