现场测量和电化学试验结果表明，引碧输水管道途经的临海土壤环境具有低电阻率、高Ｃｌ－含量的特点；碳钢在临海土壤中的腐蚀速率低于海水中的腐蚀速率，但远大于相邻土壤和自来水中的腐蚀速率。通过现场模拟试验，确定了输水管道牺牲阳极保护的有关设计参数。实施保护一年后的管道极化电位检测结果表明，牺牲阳极保护工程设计合理，技术指标达到了设计与规范要求。
The results of on-site measurements and electrochemical tests show that the coastal water environment along Yinbi water pipeline has the characteristics of low resistivity and high Cl-content; the corrosion rate of carbon steel in coastal water is lower than that in seawater, but it is far Corrosion rates in adjacent soil and tap water. Through on-site simulation tests, relevant design parameters for the sacrificial anode protection of the water transmission pipeline were determined. After one year of protection, the results of pipeline polarization potential measurements showed that the design of the sacrificial anode protection project was reasonable and the technical specifications reached the design and specification requirements.
