Exploration seismology of dam foundation in cryolite zone on the first exploration stage
Presented are the method and results of exploration seismology of rock foundations on the alternative dam site of Nizhne-Timptonsk HPP. Determined were quaternary deposit thicknesses, weathering zone and massif relief (with evaluation of removal area value). Found out were the zones of crack soils in rock massif, assessed were the strain characteristics of rocks. Assessed were the values of intercrystalline porosity and 3D massif cracking by the results of ultrasonic investigations
