Author : Fugro Scott Wilson Joint Venture

Abstract

In the early morning of 22 May 2013, a landslide incident occurred at the construction site for the Development at Anderson Road (DAR) project, above Lee On Road, Sau Mau Ping. The landslide occurred on a fill slope (Slope B6) which was under construction as part of the DAR project. No casualty was reported as a result of the incident.

The Geotechnical Engineering Office of the Civil Engineering and Development Department conducted an investigation to establish the probable causes and mechanism of the landslide.

Based on the findings, the landslide was a washout failure. It resulted from the site drainage provisions at the time of failure being not efficient in conveying surface runoff off site and thereby being overwhelmed by the large volume of surface runoff arising from the intense rainfall in the early morning of 22 May 2013.
