AI Technical Summary

Technical Problem

In existing technologies for horizontal displacement measurement in reservoir dam projects, BeiDou and machine vision automated measurement are greatly affected by the environment and have large errors. The total station method with prism has large errors and a small measurement range. Manual measurement also has errors and is difficult to achieve high-precision measurement.

Method used

A string displacement gauge is used, which is connected to the dam structure being measured via a hook. A total station is used to determine the line of sight. After fixing, the horizontal displacement change is measured by the expansion and contraction of the string displacement gauge, combined with a vibrating wire reading instrument. This reduces manual reading errors and improves measurement accuracy.

Benefits of technology

By reducing errors from manual readings, the accuracy of horizontal displacement measurements has been improved, meeting the measurement requirements of dam projects.
