1）平断面测量应根据测量任务书要求,确定平断面测量的范围,应用仪器施测范围内的地物(建构筑物、道路、水系、架空物及地下电缆管道等),并注记接近路径中心线的距离和高度。
2）对被交叉跨越的 35KV 以上送电线路,必要时测绘交叉跨越分图,并注明被交叉跨越线路相邻两杆塔的杆号、型式、杆塔高度。
3）大跨越线路与弱电线路(电报、电话、有线广播、铁路信号线等)平行接近,经设计估算有危险影响时,应测绘弱电线路危险影响相对位置图。
4）断面测量,可采用视距法或直接丈量的方法测定其距离和高差。
5）采用视距法施测时,断面点宜就近桩位施测,不得越站观测。需要临时加设测站时,应进行正倒镜对向观测,其距离较差允许相对误差为 1/150,高差较差允许为 ±0.2M,成果取中数。
6）选测的断面点,应能反映地形起伏变化和地貌特征
 

1) flat cross-section measurement should be based on the measurement task book requirements, level cross-section measurement to determine the scope of application of measuring instruments within the scope of features in Shi (built structures, roads, water systems, overhead structures and underground cables, pipes, etc.), and near the path of Note centerline distance and height.
2) to be cross-over across the 35KV power transmission lines, if necessary, cross mapping across the sub-map, and marked by cross-cutting across the lines of two adjacent towers rod number, type, tower height.
3) Large cross-lines and weak lines (telegraph, telephone, cable radio, railway signal lines, etc.) parallel to close, has been designed to estimate the risk implications of the weak lines to be dangerous implications for mapping the relative location map.
4) cross-section measurements, line of sight can be used directly measured law or determined by the method of its distance and elevation difference.
5) Use of line of sight Fasch measurement, the cross section should approach the nearest point of pile-bit Shi measurement, not the more stations observed. Require temporary additional stations should be carried out is inverted microscope to observe, their distance to allow the relative error of less 1 / 150, height difference less allows for ± 0.2M, the results obtained in a few.
6) The selected cross-section measuring point should be able to reflect the changes and geomorphological features undulating terrain
