Report Title : Review of Selected Landslides Involving Soil-Nailed Slopes (2008), 98 p.

Author : F.H. Ng, M.F. Lau, K.W. Shum & W.M. Cheung


Soil nails have been used extensively to upgrade substandard man-made slopes since the 1990's. Between 1993 and 2006, twenty-five minor landslide incidents (< 50 m3 in volume) have been reported on engineered soil cut slopes with permanent soil nails in Hong Kong.

The report presents the findings of a review of selected landslides involving soil-nailed slopes in Hong Kong.

The key objectives of the study are to collate the background information on failures of soil-nailed slopes and identify key areas that deserve attention in further improving the performance of soil-nailed slopes in Hong Kong.
