| Abstract: |
Terrestrial microwave interferometry is a sophisticated technique in geodesy to measure relative displacements of a structure with a high accuracy of up to 0,01 mm at a sampling rate of 200 Hz from a distance of up to 1000 m. One of the big advantages of the method is that the object to be measured does not have to be instrumented or walked-on as the microwaves are reflected by its surfaces and edges. In combination with structural analysis, the in-situ measurements can give a strong support for the condition assessment for a variety of structures in civil engineering and for validating their structural behaviour, robustness and safety. Examples of full-scale measurements of railway bridges and wind turbines will be presented in this paper. |
