Report Title : Investigation of Some Selected Landslides in 1999 (Volume 1) (2001), 148 p.

Author : Fugro Maunsell Scott Wilson Joint Venture

Abstract

This GEO Report consists of two Landslide Study Reports on the investigation of selected slope failures that occurred in 1999. The investigations were carried out by Fugro Maunsell Scott Wilson Joint Venture (FMSW) for the Geotechnical Engineering Office as part of the 1999 Landslide Investigation Consultancy.

Section 1 of the report presents the findings of a detailed study of a landslide (GEO Incident No. MW 1999/8/37) which occurred on 24 August 1999 in a cut slope above South Lantau Road, near Lai Chi Yuen on Lantau Island. Debris from the landslide, with an estimated volume of 1000 m3 was deposited on South Lantau Road, blocking both lanes to traffic and causing damages to a parked vehicle and bus shelter. No fatalities or injuries were reported.

Section 2 of the report presents the findings of a detailed study of the 1000 m3 landslide (GEO Incident No. MW 1999/8/14) that occurred on cut slope No. 6NE-D/C57 opposite the Lookout Point at Route Twisk near Shek Kong on 23 August 1999. Debris from the landslide completely blocked Route Twisk for several weeks. No casualties were reported following the landslide. A second failure occurred near the crest of the scar, 5 days after the initial landslide during urgent repair works. Two labourers working on the slope suffered minor injuries as a result of the second failure.
