摘要

季节因素引起的土壤结构的改变必然影响地网的安全性能。对于均匀土壤和双层土壤模型

采用数值分析技术讨论了考虑季节影响后接地系统的设计方法。接地系统的优化设计应在充分调查当地冻土层厚度的基础上

分析比较不考虑冻土层时在存在冻土层季节时的安全性

和考虑冻土层时在无冻土层季节的安全性能

从而综合得到优化设计的方法。

Abstract

The changes of soil structure caused by seasonal factor would affect the safety of grounding system. A numerical method is used to analyze the design methods of grounding system in uniform and double-layer soil models. The optimal design scheme of a grounding system considering the influence of seasonal factors should be comprehensively determined by comparing the safety of the grounding system in normal and frozen seasons on the basis of fully investigating the local frozen soil thickness.
