This GEO Report consists of two Landslide Study Reports carried out by the Landslip Investigation Division in 2001.
They are presented in two separate sections in this Report.
Section 1: Detailed Study of the 24 August 2000 Landslide on Fill Slope No. 15NE-B/FR123 Below Shek O Road
This report presents the findings of a detailed study of a landslide (GEO Incident No. HK2000/08/04) which occurred on 24 August 2000 on a fill slope below Shek O Road opposite No. 18 Shek O Road. The landslide involved the collapse of a portion of Shek O Road and an associated concrete retaining wall. Shek O Road was subsequently closed, which cut off the sole access to Shek O Village and Big Wave Bay. The landslide debris travelled downslope into a stream course and its outwash was subsequently deposited onto the golf course of the Shek O Country Club. A taxi fell into the landslide scar, but no fatalities or injuries were reported as a result of the landslide.
Section 2: Detailed Study of Selected Landslides on Slope No. 11NE-D/C45 Hiu Ming Street Kwun Tong
This report presents the findings of a detailed study of a cut slope (No. 11NE-D/C45) at Hiu Ming Street, Kwun Tong, which has been affected by several landslides since its formation in 1966. The report focuses on two landslides, GEO Incident Nos. K93/9/17 and ME2000/08/04, which occurred on 26 August 1993 and 3 August 2000 respectively. The 1993 landslide involved a 20 m wide section of the slope. The resulting debris, with an estimated volume of about 200 m3, destroyed part of the boulder fence and inundated a portion of a tennis court below. The 2000 rockfall involved the detachment of a 15 m3 rock block, which landed in a fenced-off area between the toe of the slope and a playground. No fatalities or injuries were reported as a result of the landslides.
