本文理论推导了接地电阻的快速计算公式,非常适用于野外施工,并提出了多个电极布设条件下,减弱屏蔽效应的极间距与工区土壤电阻率无关,只取决于电极的尺寸,通过数值计算,验证公式的正确性,最后给出了施工方法.
This paper deduces the fast calculation formula of grounding resistance, which is very suitable for field construction. It is proposed that under the condition of multiple electrodes, the pole spacing that weakens the shielding effect has nothing to do with the soil resistivity of the working area, but only depends on the size of the electrode. , Verify the correctness of the formula, and finally gives the construction method.
