本文根据国外关于利用大地测量方法监测大坝变形的文章综合介绍这方面的进展情况。如精密导线测量用于测量拱坝位移及解决导线起始数据不足的方法,布设大地控制网监测大坝外部变形,变形网的优化设计及变形分析中要注意的一些问题。
This article presents an overview of progress made in this area based on an article by abroad on monitoring dam deformation using geodesy. For example, the precision wire measurement method is used to measure the displacement of the arch dam and to solve the problem of the initial data of the wire. The earth control net is deployed to monitor the external deformation of the dam. The optimization design of the deformation net and some problems to be noticed in the deformation analysis are also discussed.
