摘要： 本文介绍了金沙江水网七个井台防雷地网的场地地质环境条件与四个施工阶段及各个阶段的接地电阻值大小, 分析了影响接地电阻大小的因素, 认为井区的地质环境条件是影响接地电阻大小的决定因素, 加大防雷地网的规模与加深角钢桩的深度是降阻的有效途径, 合理使用降阻剂与加做降阻池等措施有一定的降阻效果。

Abstract: This paper presents the geologic environment condition and the 4 construction stages of lightening prevention ground-network and the earthing resistances in the 7 well-stations of the groundwater observation network in the Jinshajiang reservoir area, and factors influencing earthing resistances are analysed. It is found that the crucial influencing factor of earthing restance is the geologic environment condition in the well area,and the effective way of reducing earthing resistance is increasing the network dimension and the depth of angle steel poles, and there are some effect of reducing resistance while applying reducing resistance agent and adding water-pond for reducing resistance rationally.

Key words: Lightening prevention ground-network, Earthing resistance, Groundwater observation network in Jinshajiang reservoir area
