In this article deals with the study fluctuations in the beam of the bridge over Naryn river in the explosion at Kambar-Ata 2 for creating natural dams. Full-scale experiment was conducted to determine the dynamic parameters of the vibrations of the beam bridge, located near the explosion. The experiment was conducted using a portable engineering seismometric station Kyrgyz State University of Construction, Transport and Architecture. The study experimentally defined dynamic parameters of reinforced concrete beam bridge, the obtained records of displacement, acceleration of ground motion, the support and the span of the bridge. The results are processed and records fluctuations are the results of the study. The results dynamic parameters can be used in the calculation of bridges on the seismic effects.
