The recurrence of slope failures in residual soils of Hong Kong is analysed for the period 1950 to 1973, and various factors contributing to the instability are described. It is postulated that the prime cause of the failures is direct infiltration of rain water into the surficial zones of the slopes, producing a loss of effective cohesion following the saturation of the soil. Prevention of slips implies protection against excessive infiltration.
