Based on some discussions on the mathematic model set up for the cathodic protection potential field , a two - dimensional boundary element method ( bem ) is developed , and by using which , a study on the shielding effect resulted from some typical inner structures such as the reinforcing elements and the partition walls with man holes on distribution of potential and current density in the cathodic protection is performed . the investigated parameters which affect the shielding effect in the calculating model include : the height and thickness of the reinforcing elements , the distance between the anode and the reinforcing elements , and the diameter of man hole on the partition walls , and so on
本文在讨论了阴极保护电位场问题的数学模型的基础上，以二维边界元法对阴极保护问题中的电位及电流密度分布进行了模拟计算，重点对船舶压载舱中的典型结构如加强筋、人孔等在阴极保护中所产生的屏蔽效应进行了分析和研究，通过对不同高度、厚度的挡板及不同孔径的带孔板所产生的屏蔽效应进行模拟计算，首次得到了一些对实际工程设计具有重要参考意义的见解。
