Application of the interferometric radar for dynamic tests of corrugated steel plate (CSP) culvert

The paper presents the results of selected experimental tests under dynamic loads, which were conducted on a corrugated steel plate (CSP) culvert. The dynamic loads were caused by the passages of various trains. The displacements and vibration frequencies of the culvert were measured. The microwave interferometric radar and inductive gauge were used for monitoring of displacements of this railway culvert. The conventional inductive gauge was applied to verification of results received by the radar. Conclusions drawn from the tests can be helpful in the measurements of such culverts using the microwave interferometry method.
