Variations in the electrical parameters of the rock massif in the region of the high-altitude dam of the Chirkey HPP as an indicator of the unstable state of the medium
Abstract
The article presents some data of experimental observations of varying apparent resistance of rocks and electrical field in the drill hole located near the dam of Chirkeiskaya HPP as of 2012. Thanks to data analysis, it is possible to conclude that these variations have been preconditioned by opening of cracks in solid rocks near the measuring probe. Crack opening increases water infiltration from the water reservoir into the surrounding solid rocks, so that electric field intensity depending on infiltration rate grows. At the same time, volume increasing of pores and cracks in the rock causes its electrical resistance to decrease.
