Abstract

The article made the analysis of time series of water level in Chirkei reservoir, temperature and pressure of the atmosphere to determine its effect on the electrical resistance of rocks in the borehole located in the area starboard of the high dam hydroelectric power station. Based on the analysis found: 1) no effects of seasonal changes in temperature and pressure of the atmosphere on the electrical resistance of rocks in the borehole; 2) the presence of high regard with the correlation coefficient of 0.9 for the module between the seasonal change of water level in the reservoir and an electric resistance of rocks. As the mechanism of such influence is considered the simultaneous influence of two different seasonal factors, deformation of rocks and lateral filtering.
