Propagation characteristics of a blast-induced seismic effect in the beds of structures during construction of the dam at the No. 2 Kambaratinskaya HPP-2

The propagation characteristics of blast-induced oscillations in slightly cohesive cover soils and rocks are examined during construction of the No. 2 Kambaratinskaya HPP. A selective empirical evaluation of the dynamic characteristics of the entities is given on the basis of spectral analysis of vibrations recorded in their beds and structures. The distribution of process parameters over the area covered by seismometric observations in the Kirgiz Republic is recommended as initial base information for evaluation of the seismic effect of a large-scale blast.
