【摘要】 三峡双线五级船闸高边坡工程共安装了1000kN 预应力锚索229束,3000kN 预应力锚索3975束,400kN 高强锚杆9.7万根,加固岩石边坡楔形块体1054个,完成的边坡锚固量和岩石块体支护量均属世界之最。由于预应力锚索在船闸高边坡中起着至关重要的作用,在船闸预应力锚索设计和施工过程中对锚索的防腐措施进行了系统研究,并收集国内外锚索耐久性研究最新成果,结合船闸锚索的地下环境对锚索耐久性进行了全面研究。研究成果显示,三峡船闸高边坡预应力锚索防腐措施可靠,耐久性可以保证。更多还原

【Abstract】 There are 229 bundles of 1 000 kN prestressed anchorage cables,3 975 bundles of 3 000 kN prestressed anchorage cables, 97 000 roots of 400 kN high-tensile anchors and 1 054 wedge-shaped blocks of reinforced rock slopes mounted in the high slope project of the TGP’s double line fifth-grade shiplock,in which the mounts of slope anchoring and rock block support are the maximum in the world.As the prestressed anchorage cables’s key role in shiplock high slope,during design and construction the shiplock’s prestressed anchorage cables,systematic research on antiseptic technique of anchorage cables is completed.In addition with the interior and oversea newest-researches on anchorage cables’s endurance are collected;at the same time considering its underground surroundings anchorage cables’s endurance is studied roundly.Those researches show that prestressed anchorage cables’ aseptic measures and endurance are reliable in the high slope of the TGP shiplock.更多还原
