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