Abstract

Soil resistivity is one of the direct factors affecting the grounding resistance of building lightning protection system. In order to understand the influence of meteorological factors on soil resistivity, this paper analyzes its variation law and relationship with ground temperature, soil humidity and precipitation through continuous monitoring of soil resistivity at different depths in Langfang, combined with meteorological data. The results show that: The soil resistivity has obvious seasonal variation, with the maximum in February and the minimum in July and August. The resistivity of shallow soil is larger than that of deep soil, and changes more obvious with season. The resistivity of the whole soil layer is negatively correlated with soil temperature and soil moisture. When the soil moisture is high, the precipitation cannot reduce the soil resistivity continuously.
