对高速公路两点之间的高差进行测量具有重要的作用,通常两点之间的高差要保持在一个合理的范围内容,如果在测量工作中两者的误差较大,应及时地调整,不然会影响高速公路车辆的行驶安全性。因此,本文将主要从水准测量的基本概念以及高速公路水准测量的方法这两个方面进行阐述,为提高高速公路测量的准确性提供合理的参考意见。 It is very important to measure the height difference between two points on the expressway. Usually, the height difference between two points should be kept within a reasonable range. If there is a big error between the two measurements, the adjustment should be made in time , Otherwise it will affect the driving safety of highway vehicles. Therefore, this article will mainly elaborate the basic concept of level measurement and the method of highway level measurement to provide reasonable reference for improving the accuracy of expressway survey.
