Abstract—The paper presents the results of selected experimental tests under dynamic loads that were conducted on a corrugated steel plate culvert. The tested railway object in the cross section has two spans in shape of closed arch. The effective length of shells is L1 = L2 = 4400 mm. The dynamic loads were caused by the passages of various trains. The displacements and vibration frequencies of the culvert were determined. The microwave interferometric radar was used for monitoring of displacements of this railway culvert. The maximum displacements of the culvert crown do not exceed 0.65 × 10 –3 m. The typical frequencies of the railway culvert to passing trains were usually in the range of 0.6 to 3.0 Hz. They were obtained during passage of the heavy freight trains. Conclusions drawn from the tests can be helpful in the measurements of such culverts using the microwave interferometry method.
