Update on landslip investigations

The Geotechnical Engineering Office (GEO) has made some progress in its investigations of the two landslips at Chai Wan and Wong Chuk Hang.

The preliminary results of the search of background information show that the failure in Fei Tsui Road at Chai Wan occurred in a cut slope formed in weathered volcanic rock and soil on government land between 1975 and 1978. The original dimensions of the slope were about 25 metres high, 180 metres long, inclined at an angle of about 65 degree. There is a strip of vacant flat land about 10 metres wide between the toe of the slope and Fei Tsui Road.

The slope was first inspected by government consultant in August 1977 and registered as number 11SE-D/C42. Due to the presence of squatter huts above the slope crest, the consequence of failure was initially assessed as high. Therefore the slope received a high priority for a preliminary GEO stability study (also known as Stage 1 Study).

The study was carried out in September 1979. The results showed that a mechanism for failure could exist but the possibility of failure actually occurring was small. The consequence of failure was not considered high as it was judged that any failure debris would be contained within the flat grassed area at the slope toe and traffic on Fei Tsui Road would not be affected. A failure sufficiently large to affect the squatters above the slope crest was considered very unlikely.

The squatters were removed between 1989 and 1990.

The Baptist Church building was constructed between 1986 and 1987 at a distance of 25 metres from the toe of the slope on the other side of Fei Tsui Road.

Two minor failures occurred on the slope in 1987 and 1993, both being small rock slides with approximate volumes between 40 and 70 cubic metres. In both cases the failure debris came to rest in the flat grassed area between the slope toe and Fei Tsui Road. These two rock slides confirmed the existence of failure mechanisms and also the judgement that the debris would not affect the road.
