柳州维义大桥桥墩沉降监测运用中点三角高程测量方法的精度分析

摘要

With method is gradually technology development and improvement of accuracy in distance surveying, trigonometric leveling favored by the majority of surveyors. By an actual project, this article majorly introduced the use of the midpoint of the triangle leveling to monitor settlement of offshore piers and analyze the sources of error and accuracy of the measurement method to described its efficiency,flexibility and practicality in engineering survey.%随着测距技术的发展、测距精度的提高，三角高程测量方法正逐步受到广大测绘工作者的青睐，本文通过工程实例，介绍了运用中点三角高程测量对离岸桥墩进行沉降监测的方法，并对这种测量方法的误差来源及精度进行了分析：阐述了这种测量方法在工程测量运用中的高效性、灵活性和实用性.
