| 330 | _aThis paper is dedicated to the development of techniques allowing for design solutions to be refined on grounding devices. The resistivity is used in the design of grounders in dependence on the soil humidity, temperature, and density. To determine soil humidity at the depth of soil occurrence, two models are used: depending on the season at a depth of up to 1 m and depending on the level of groundwaters at depths of more than 1 m. The models are developed based on the fuzzy logic theory and data from water stations and geological exploration. The technique and corresponding dependencies are used to find the temperature of soil layers during a year and calculate soil resistivity. Temperature was simulated based on the Fourier theory of thermal conductivity and data from weather stations. It is shown that these methods and dependencies allow one to calculate more precisely the resistances of grounders at the design stage. The obtained in vitro dependencies of soil resistivity on the soil humidity and density are considered. These dependencies allow one to refine the dynamics of change in the grounder resistance from the time of installation to complete soil subsidence. | ||
