Popis:	The long-term performance of soil-nailed slopes requires that the soil nails should be able to withstand corrosive attack from their local environment. Various types of corrosion protection methods for steel soil nails have been examined. Protection approaches used in Japan, France, UK, Nordic countries, USA and Germany are reviewed and compared with that currently being used in Hong Kong. Two case examples of corrosion of steel soil nails are described. They provide useful information for establishing the corrosion rates of hot-dip galvanising and steel soil nails. A survey of the corrosion potential of soils in Hong Kong has been conducted and this included the determination of the relevant physical and electrochemical properties of the soils. The survey results are presented and analysed. They show that a significant portion of the soils that had been taken from potentially aggressive sites could have a relatively high corrosion potential. Use of heat-shrinkable sleeves for protecting steel couplers an...
