通过对柳州农业气象试验站办公楼接地电阻为期16个月的不间断测试,并结合该站土壤相对湿度的观测数据,总结分析土壤相对湿度与接地电阻的变化关系,结果表明:土壤相对湿度与接地电阻的相关性存在显著的负相关性,在相同土壤相对湿度条件下,随着土壤深度的增加,土壤相对湿度对接地电阻的影响更显著。
Based on the 16-month uninterrupted ground resistance test of Liuzhou Agricultural Meteorological Experimental Station Office Building and the observation data of the soil relative humidity at the station, the relationship between soil relative humidity and ground resistance is analyzed. The results show that the relationship between soil relative humidity and There is a significant negative correlation between the grounding resistance and the grounding resistance. With the same soil relative humidity, the influence of soil relative humidity on grounding resistance is more significant with the increase of soil depth.
