... ABSTRACT: The Geotechnical Engineering Office keeps comprehensive rainfall and landslide data. A GIS database of all sizeable man-made slopes and retaining walls in Hong Kong is also available. Apart from basic information on slope geometry (height and gradient), the database contains other...

... ABSTRACT: The demand for land in the hilly terrain of Hong Kong means there is increasing pressure for developments to enc roach onto the natural terrain. This paper examines some salient aspect s of the design of barriers against natural terrain landslides and channelized debris flows...

... INTRODUCTION: Two unusually large landslides in Hong Kong in August 1995, both of which caused loss of life and substantial damage to property, were influenced by localised concentrations of low strength, kaolin-rich zones within the weathered rock mass (Kirk et aI., 1997). Plate 1 shows one...

... (major and minor) incidents, and accounted for 100% of all major failures of engineered slopes. In Hong Kong, it is generally recommended to design to a minimum Factor of Safety (FoS) of 1.2 for a 1 in 10 year return period groundwater condition, and a FoS of 1.0 for 1 in 1,000 years amongst other...

... are important in understanding the behaviour of weathered rocks. Some of the issues involved in tunnelling and underground excavation in tropically weathered rocks are illustrated with examples of observed performance in four selected rocks found in Hong Kong and Singapore. The four selected rocks consist...

... Estate in Hong Kong failed. The resulting mud avalanche buried the ground floor of the block killing eighteen people. This disaster had wider implications because 71 persons were killed in a slope failure, also in fill and also at Sau Mau Ping in 1972. The Final Report of the Commission of Inquiry...

... ABSTRACT: The weathering process of a rhyolitic tuff in Hong Kong has been studied by chemical analysis, petrographical analysis and magnetic susceptibility tests. Based on the stable constituent hypothesis, a new theoretical weathering model is proposed to investigate the chemical weathering...

... ABSTRACT: Full scale load test data give very variable and sometimes very low shaft resistance for large diameter bored piles founded in Hong Kong decomposed granite. These observations were discussed and explained in this paper. INTRODUCTION Large diameter bored piles in Hong Kong...

... ABSTRACT: Rapid urban development in the hilly terrain of Hong Kong involves the construction of high-rise buildings, many of which are supported on large diameter bored piles. These piles may sometimes have to be founded in slopes and have to resist severe wind loads during typhoon season...

... ABSTRACT: Three series of triaxial tests have been conducted to investigate the behaviour of loosely compacted fill in Hong Kong. These series included consolidated undrained tests on saturated samples, constant water content tests on unsaturated samples with suction measurements and shear...
