摘要
用矩量法对埋在均匀土壤中含水平钢筋网的矩形混凝土接地系统在地面产生的电位进行了计算.并结合Matlab语言,绘制了地面电位三维分布图.大量模拟计算表明,当混凝土的电阻率比土壤的电阻率小很多时,地面电位是在混凝土的边角附近变化最大.
The moments method is adopted to calculate the ground potential in the grounding system in a rectangular concrete with horizontal steel rods.A three-dimensional distribution map of the surface potential is also drawn by means of Matlab language.A lot of analog data show that the ground potential varies most in the edge areas of the concrete when the resistance of the concrete is smaller than that of the soil.
