摘要

In the simplest form this method consists of recording the number of landslides which occur each year in an area of interest, such as along a road or railway. It may be extended to include the type of sliding, e.g. on natural or constructed slopes, or on cuts and fills, and characteristics such as volume or area of landsliding. Chowdhury & Flentje (1998) discuss the use of a database to record such data in a systematic way. Examples of this approach are given in: Morgan et al (1992) where the historic record of landsliding was used to assess the magnitude and probability of debris flows; Fell, Finlay & Mostyn (1996(a)), where records collected by the Geotechnical Engineering Office of Hong Kong were used to estimate the annual average probability of cut, fill, and retaining wall failures; examples which include rockfall are described in Moon et al (1992), Cruden (1997) and Moon et al (1996).
