摘要
交叉跨越测量是输电线路工程设计、施工、竣工等环节重要的测量要素,交叉跨越测量成果是反映输电线路对跨越物的最终交叉跨越距离,它直接影响输电线路工程的质量、工程造价及运行安全。本文针对交叉跨越物无法直接到达的情况,对交叉跨越测量方法进行探讨,结合经纬仪、全站仪、GPS等不同的测量仪器设备,给出相应的测量方法、公式推导、计算方法及注意事项。
Crossover survey is one of the most important methods used in the design and construction of electric transmission lines.What this method can do is to reflect the electric lines span between objections,and affect transmission lines＇ quality,cost and security.This paper discusses how to do crossover surveying when objections needing to cross over are not available to approach.According to the kind of instruments to be used,such as theodolite,total station device and GPS,we introduce corresponding method of measuring and calculating,and matters needing attention.
