Report Title : Investigation of Some Selected Landslides in 1998 (Volume 5) (2001), 167 p.

Author : Fugro Scott Wilson Joint Venture

Abstract

This GEO Report consists of two Landslide Study Reports on the investigation of selected slope failures that occurred in 1998. The investigations were carried out by Fugro Scott Wilson Joint Venture (FSW) for the Geotechnical Engineering Office as part of the 1998 Landslide Investigation Consultancy.

Section 1 of the report presents the findings of a detailed study of an area of instability in the natural terrain at Queen's Hill, Burma Lines Camp, Fanling. Instability in the form of localised landslides, tension cracks and disturbed ground were identified in December 1997 during upgrading works to Slope No. 3SW-B/C12 under the Landslip Preventive Measures (LPM) Programme. Two low-rise accommodation blocks at the toe of the slope were evacuated as a precautionary measure following recommendations made by the Geotechnical Engineering Office (GEO) in March 1998, with another two blocks being evacuated following further recommendations by the GEO in September 1998. There have been no casualties as a result of the observed instability.

Section 2 of the report presents the findings of a detailed study of a landslide (GEO Incident No. HK 98/6/8) which occurred on the heavily vegetated hillside above 7C Bowen Road, Hong Kong in the morning of 11 June 1998. The landslide debris came to rest on the rear yard of the residential building of 7C Bowen Road. No one was injured in the landslide.
