Abstract
Highlights the importance of geotechnical investigations in site selection, design and maintenance of life-line structures in multiple hazard prone areas. The Boar River Pipeline, carrying part of Kingston's water supply, was damaged by a debris flow originating on the eastern slope of Bromley Hill, following the passage of Hurricane Gilbert over Jamaica on September 12, 1988. Regional and site-specific geotechnical investigations indicate that landslides are ubiquitous in the region, especially on east-facing slopes, and that the slide, which damaged the pipeline, is a relatively shallow failure. In due time, the slide may stabilize itself provided there are no extreme weather events; as a short-term solution, artificial measures of slope stabilization are recommended. However, since the entire slope is involved in sliding and favourable conditions for future failures exist in the area, it is recommended that the failed slope be avoided altogether and the pipeline be relocated.....
