摘　　要：锚杆的耐久性及使用寿命问题是锚固类结构耐久性及使用寿命的重要影响因素,该文开展了锚杆在潮湿空气和Na2SO4溶液中有、无载荷耦合情况下的腐蚀对比研究,进行锚杆腐蚀的耦合因素分析,探讨了锚杆在多因素耦合腐蚀条件下腐蚀机制,并得出了相关结论。The durability and service life of anchor rod are important influence factors of the anchor structures service life and durability. This text has been performed contrast study of the anchor rod under condition of in damp air or in Na2SO4 liquor, at the same time, the anchor rods may have loads or not. The coupling factors analysis of anchor rod is carried out. The corrosion mechanism of anchor rod under condition of the coupling factors is discussed. Some related conclusion is provided.
