| 摘 要： | 岩土预应力锚索的防腐至关重要,一旦发生应力腐蚀将有可能产生致命破坏。我国很多工程对施加锚固力较为重视,对锚索的腐蚀破坏与防腐缺乏认识。本文论述了岩土预应力锚索的腐蚀机理和特点,比较了国内外岩土锚固规范防腐要求的差别,在此基础上,提出了适用我国锚固工程特点的岩土预应力锚索防腐建议。

| Abstract: | The antisepsis of geotechnical prestressed anchorage cables is crucial.It will induce deadly destruction in case of stress corrosion.It is very important to impose anchoring force in lots of engineering projects in China.However,it is in a state of complete ignorance of corrosion failure and antisepsis of anchor cables.Based on the discussion of corrosion mechanism and characteristics of geotechnical prestressed anchorage cables,after comparing differences of requirements for anticorrosion between the domestic and foreign standards of geotechnical anchorage,some suggestions for geotechnical anchorage cables were proposed,and they would be suitable for the engineering practices in China. |
