Analysis of labor accidents caused by slope failure

Abstract

Accidents due to slope failure frequently occur at excavation sites. About from 15 to 30 workers die annually in accidents attributed to slope failure or rock fall during slope-cutting work in Japan.
In this study, about 121 fatal accidents were attributed to slope failure and rock fall from 1989 to 2001. They were studied to develop effective countermeasures to reduce such accidents. The profiles of the slope failures were studied and classified by various factors, such as geology, topography, slope height, gradient, scale of failure, and rain fall conditions, etc.
