Abstract

This report presents the findings of a detailed study of a landslide (Incident No. 2007/07/0050), which occurred on 30 June 2007 at the southern portion of retaining wall No. 11SE-C/R7 and the adjoining hillside below Repulse Bay Road. The landslide involved a failure volume of about 600 m³. Most of the debris was deposited on the hillside immediately below the registered retaining wall, whilst some was deposited on an ephemeral drainage line some 30 m below Repulse Bay Road. As a result of the landslide, a section of the northbound lane and its adjacent pedestrian footway of Repulse Bay Road were undermined, and the supply of freshwater to the nearby residents was temporarily suspended. No casualties or injuries were reported as a result of the incident.

The key objectives of the detailed study were to document the facts about the landslide, present relevant background information and establish the probable causes of the failure. Recommendations for follow-up actions are reported separately.
