金属板状电极的接地电阻

Grounding resistance of metal plate electrodes

文章研究任意布设的金属板状电极(电极组)的接地电阻,给出了敷设在地面的和深埋于地下的水平圆形金属板以及垂直埋设的金属半圆板接地电阻的计算公式,其中有的公式是前人未曾给出的。比较了金属板状电极与金属杆状电极、半球状电极接地电阻的差异,研究了金属板状电极之间的距离与接地电阻的关系。文章为广大野外电法勘探人员设计和布置发送(供电)电极(组)提供了依据,有利于取得最佳的供电效果。

The grounding resistance of metal plate electrodes （group） which are randomly laid, is studied in this paper. Calcu- lation formulas of grounded electrode of horizontally laying on ground or in earth and vertically buried semicircular metallic plate in ground are given. Some of them are not listed in previous study. The differences of grounding resistance between circular metal plate e- lectrode, metal rod like electrode and hemispheric metal electrode are studied and compared. The relationship of distance between me- tallic plates and grounding resistance is also studied. The study result will provide field electric prospectors basis for design and ar- rangement of power supply （sending） and electrodes （group） .in order to aehive the best effects of power supply.
