摘要
预应力锚固结构广泛应用于水电、交通、国防等领域岩土加固工程,锚固失效严重威胁工程安全。腐蚀造成的锚固材料劣化是影响锚固体整体耐久性的主要原因之一。从锚固材料腐蚀机理、工程服役现场试验和室内模拟加速腐蚀试验等方面综述了预应力锚固材料腐蚀耐久性的研究进展,并在此基础上提出了未来的研究方向,为现有锚固结构使用寿命和安全性评估及防腐措施制定提供了一定参考。
Prestressed anchorage structures are widely used in geotechnical reinforcement engineering in the fields of hydropower,transportation,national defense and others.The failure of anchorages seriously threatens engineering safety.The deterioration of anchorage materials caused by corrosion is one of the main reasons that affect the overall durability of anchors.The research progress on the corrosion durability of prestressed anchorage materials is reviewed from the aspects of corrosion mechanism,field test and indoor accelerated corrosion simulation test,and on this basis,the future research direction is put forward,which can provide a certain reference for the service life and safety evaluation of existing anchorage structures and the formulation of anti-corrosion measures.
