摘　　要：宝钢一期工程使用的钢管桩打入地下已25年,桩身腐蚀关系其使用寿命及宝钢的安全。文章通过设计使用及实测分析认为防腐蚀设计是安全的,并为管壁腐蚀厚度取值提供了实践依据。Steel piles used in Baosteel Phase One Project have been driven into ground for 25 years. The corrosion condition of these piles would influence Baosteel structures safety and duration. This article testifies that the anticorrosion design for Baosteel Project is safe through analyzing the steel pile's condi tion . It also provides the thickness value for tube wall on the basis of the practical evidence.
