With a land area of only 1,076 km2 and a population of over six million people, Hong Kong is one of the most densely populated places in the world. In addition, the topography of Hong Kong is rugged. In view of limited flat land area in Hong Kong, intensive urbanization of the lower portions of hillslopes in many parts of the territory has been the only feasible approach to cope with the needs of continuing development. The development of roads and buildings often necessitates numerous hillside cuttings and embankments. The stability of these man-made slopes is of prime concern as the impact on the community can be tremendous in the event of slope failure. Failure of these cuts and embankments often simply causes traffic delays, however, more serious landslides may overwhelm inhabited downslope areas with debris avalanches, slumps and falling boulders.

Of the contributing factors associated with the occurrence of landslides, water pressure is frequently the major. In Hong Kong most landslides are rain-induced, rainfall is high but seasonal, averaging about 2000 mm during the summer months when Hong Kong is frequently threatened by troughs of low pressure and tropical cyclones. Disastrous landslides associated with heavy rainfall include the following; Sau Mau Ping Resettlement Estate 1972, Po Shan Road in 1972, Kwun Lung Lau in 1994, Fei Tsui Road 1995 and Shum Wan Road in 1995.

The Shum Wan Road Landslide in Aberdeen is the largest landslide to have occurred in Hong Kong since 1976. It involved two distinct slides that occurred almost simultaneously. A minor failure of the fill embankment occurred below a passing bay on Nam Long Shan Road which triggered a major landslide at a hillside between Shum Wan Road and Nam Long Shan Road. In this study various aspects of the landslide and subsequent slope rehabilitation works are presented.
