通过模拟试验测试了铜、镀锌钢和碳钢等三种储油罐外底板接地材料作为阴极保护接地材料的适用性。结果表明：铜和碳钢接地材料不适作储油罐外底板接地材料；当阴保电位为-0.85～-0.95 V（相对于CSE）时，镀锌扁钢接地材料适用于储油罐阴极保护接地材料。提出了接地材料与阴极保护不相容时的解决措施。

Through simulation test, the applicability of three kinds of grounding materials of the outer bottom plate of oil storage tank, such as copper, galvanized steel and carbon steel, was tested as the cathode protection grounding material. The results showed that copper and carbon steel grounding materials were not suitable as grounding materials for the outer bottom plate of oil storage tank; and when the cathodic protection potential was -0.85 ~ -0.95 V(vs. CSE), galvanized flat steel grounding material was suitable for the cathodic protection grounding material of the oil storage tank. To solve the problem that grounding material was incompatible with cathodic protection,solutions were proposed.
