Displacement Measuring Device for Load Test of Bridges Using a Laser Doppler Vibrator and Method Testing Using it

摘要

The present invention uses a laser Doppler displacement meter to accurately measure the displacement of bridges constructed in rivers, seas, and mountainous terrain, which cannot perform a load test from the lower part, even from a long distance. Displacement measurement for a bridge load test using a laser Doppler displacement meter It relates to an apparatus and a load test method using the same, comprising: a support member, a driving unit, a laser Doppler displacement measuring instrument that rotates up, down, left, and right by a driving unit, an inclinometer, a driving unit control unit and a control unit. By using an inclinometer, it is possible to accurately carry out the load test of the bridge, which is constructed in the sea, river, and mountain terrain and is not possible to perform the load test at the lower part of the bridge. By rotating the laser Doppler displacement meter at each coordinate and automatically performing the load test at multiple locations at once, the displacement measuring device for the load test of the bridge using a laser Doppler displacement meter that can improve the convenience and workability of the operator and the load test method using the same. to provide.
