| 摘 要： | 钢质贮罐底板外侧阴极保护时的电位分布往往不均匀，本文用有限元法计算了几种情况下的电位分布和电流分布规律，并在此基础上讨论了多种因素对电位分布的影响，包括土壤的电阻率，贮罐底板外侧表面状态，阳极的数量和分布以及极化电量等，这些结果可以解释罐底阴极保护的特征，这个计算方法可用于贮罐底板外侧阴极保护系统的设计。

| Abstract: | he potential distribution on external bottom of storage tank with cathodic protection is not uniform.The finite element method was applied to calculate the potential distribution and current distribution under various conditions.In the calculations various factors were considered, including soil resistivity,surface condition of tank bottom, number of anodes and their arrangement as well as cathodic polarization performance,etc.The analysis accommodated the combination of these factors as variable parameters.The results obtained could be used to interpret characteristics of the cathodic protection system.The calculation method can be recommended to engineering design for improvement of potential distribution. |
