摘要：

介绍了华润唐山曹妃甸燃煤供热电厂的场地岩土工程特性，分析了电气接地网阴极保护方式和设计计算方法。系统测试了阴极保护的效果，测试结果表明，选取镁合金牺牲阳极的方法对接地网进行阴极保护，能使接地网的保护电位达到设计要求且能取得较好的防腐效果。

Abstract: The site geotechnical engineering characteristics of Tangshan Caofeidian Coalfired Heatsupply Power Plant of China Resources were introduced. The cathode protection mode of electric grounding grid and its design calculation method were analyzed. The effects of cathode protection were tested systematically. The test result shows that to select magnesium alloy sacrificial anode in cathode protection of grounding grid can get designed protective potential and can obtain better anticorrosive effect.

Key words: grounding grid, cathode protection, magnesium alloy, sacrificial anode, corrosiveness, test pile
