摘要
通过对不同影响因素(包括土壤的水份和盐份、温度、土壤分层模型和接地体的形式等)的分析,简要地探讨了它们对土壤电阻率的影响,进一步得出这些因素均能对季节系数造成影响。因此在土壤电阻率测量中考虑季节系数是必要的,并给出了工程实际中采用的季节系数。
Through the analysis of the following factors,soil water content,soil salinity,temperature,hierarchical model and the form of grounding,the result can be obtained that these factors can affect soil resistivity and seasonal coefficient.So considering seasonal coefficient is necessary in measuring soil resistivity.The usual values of seasonal coefficient used in the engineering practice are also given in the paper.
