Report Title : Review of Notable Landslide Incidents during Slope Works (2005), 137 p.

Author : H.W. Sun & H.M. Tsui


Notable landslides have occurred at slope work sites in Hong Kong. Apart from posing a risk to the personnel on site and causing delay and cost overrun to projects, slope failures during the construction phase can also affect public safety and cause social disruption as the landslide debris may affect facilities outside the site boundary.

This report presents the findings of a review of the notable landslides that occurred during slope works, which were reported to the Geotechnical Engineering Office (GEO) from 1981 to 2002. Areas that warrant attention are identified and suggestions made to minimise the chance of occurrence of significant landslides during slope works.
