全站仪高程导线测量在油气田工程测量中的应用

Application of Elevation Polygonmetry with Total Station in Engineering Survey of Oil and Gas Fields

在油气田工程勘测中,用全站仪高程导线测量替代三(四)等水准测量,能有效提高精度,降低劳动强度。文章介绍了全站仪中间法三角高程测量的原理、方法和优点,并对该测量方法的精度进行了分析。该方法更适用于山地、丘陵等高差较大的地区,可灵活选择测站位置,测站不需对中,不需量取仪器高,操作灵活实用,能有效提高测量工作的效率。

For engineering survey of oil and gas fields,using the elevation polygonmetry with a total station to replace the third or fourth leveling can increase precision and reduce labour intensity effectively.The principle,method and advantages of the middle way trigonometric leveling with a total station are introduced and its measurement precision is analyzed in this paper.This method is more suitable for survey of biggish elevation difference areas such as mountains and hills.It can significantly increase survey efficiency because of agile selection of survey station position,no needs of survey station aligning and instrument height measuring,and easy operation.
