摘要
讨论了杂散电流电路元件模型特点。构建了基于电场的杂散电流模型,用以分析杂散电流的分布,估计其可能带来的危害;并以金属腐蚀量作为评估杂散电流危害的直观标准。通过编程对算例进行了求解和分析;计算结果表明,杂散电流对金属管道的腐蚀量趋势符合实际情况。
The stray current model based on electric field is built, after a discussion of the stray current model based on resistance components,and this model is used to analyze the distribution of stray current in subways and the oorrosion caused by it,then the oorrosion on the buried metal is used as a visual standard to evaluate the harm of the stray current. In the end, this paper uses computer to analyze the calculation instance and attempts to solve the stray current problem.
