Abstract

This report presents the findings of a detailed study of a rockfall incident (GEO Incident No. HK2001/06/008) on rock cut slope No. 11SE-A/C561 above King's Road, Tin Hau, which was reported on 25 June 2001. The detached rock block landed on the pedestrian footway at the toe of the slope. No casualties were reported as a result of the failure. The westbound lane of King's Road and a pedestrian footway at the slope toe were temporarily closed following the incident.

The key objectives of the detailed study were to document the facts about the rockfall incident, present relevant background information and establish the probable causes of the failure. The scope of the study comprised a review of relevant documents relating to the history of the site, geological mapping, and detailed observations and measurements at the landslide site, analysis of rainfall records and diagnosis of the probable causes of the landslide. Recommendations for follow-up actions are reported separately.
