| Popis: | This paper describes earlier work in this area and focuses on the role of water-content variability on slope-stability considerations in embankment design. An example is presented to illustrate certain assertions. A number of typical Indiana soils were tested with the focus upon their compacted behavior in service. The effect of water-content variability on slope-stability considerations for design of earth embankments is illustrated. It was found that the observed trends in degradation of the factor of safety in sliding failure follow a similar pattern with loosening of control on compaction water content. The study showed that the range of water content in the lift is the most important characteristic of the earthwork relative to design cross section. Thus, efforts to control the water content at time of compaction in a more efficient manner offer significant potential cost savings for construction. |
