Assessment of the Change in Elastic Properties of the Rock Mass at Various Water Levels in the Inguri HPP Reservoir

详细

The results of measuring elastic wave velocities in the rock mass of the base of the Inguri HPP dam at minimum and maximum upper pool levels (UPLs) are presented. A substantial difference in the change in longitudinal and transverse wave velocities during a rise of the UPL in the right- and left-bank abutments both in horizontal and vertical sections is established.
