摘　　要：高海拔地区土壤层很薄,甚至有岩石裸露,常规防雷接地措施难以满足建筑物防雷要求。为改善防雷接地效果,选择有代表性的场地取回土样进行试验。试验测试土壤含水率,并主要研究温度对土壤电阻率的影响。试验发现,土壤电阻率随温度降低反而升高,负温对其影响尤其明显,对防雷接地十分不利。In high altitude area, the requirements for construction lightning protection is difficult to meet by conventional grounding measures because the soil layer is so thin that rock is even bare. To improve the lightning protection and grounding effect, soil samples are taken from representative construction site for testing. Soil water content is tested and the effect of temperature on soil resistivity is mainly studied. It is found that the soil resistivity increases with temperature decrease and, in particular, the effect of negative temperature on soil resistivity increase is significant, which is very unfavorable to the lightning protection and grounding.
