高边坡预应力锚固结构腐蚀损伤与诊断研究进展
|
摘要
高边坡中预应力锚固结构所处环境极其复杂,埋置于坡体中的预应力锚杆(索)在经历长时间服役后大多会因电化学腐蚀、局部腐蚀、应力腐蚀等综合因素发生结构损伤或失效,进而导致坡体破坏,因而开展预应力锚固结构腐蚀损伤与诊断研究具有重要意义。从预应力锚固结构腐蚀损伤机理与影响因素、不均匀腐蚀行为、腐蚀条件下缺陷预应力锚固结构性能退化规律以及腐蚀评估与健康诊断4个方面详细综述了国内外的主要研究成果和进展,并分别从上述4个方面对预应力锚固结构耐久性研究进行了展望。
Since prestressed anchorage structures in high slope are surrounded by complicated environment,the prestressed anchor cable( rod) in slope will damage or fail after long time service caused by comprehensive factors such as electrochemical corrosion,local stress,stress corrosion and others,further resulting in slope failure. Research on corrosion damage and diagnosis of prestressed anchor structures are of great significance. In this paper,the main research findings and advances of prestressed anchorage structures in China and abroad are reviewed from four aspects: corrosion damage mechanism and influential factors of prestressed anchorage structure,non-uniform corrosion behavior,deterioration law under corrosion condition,and corrosion assessment and health diagnosis. The trend and prospect of durability research are also discussed from the above four aspects.
