Model testing has proven to be an effective tool in the study of
soil-structure systems. While primarily used in research work, this
method of evaluation is also applicable to the solution of many types
of complex design problems. Because of its workability and relatively
simple characteristics, sand is the most...
Nonlinear large deflection finite element analyses of a fabric
reinforced embankment on muskeg were performed to predict fabric
tension and the effect of fabric stiffness on embankment deflections.
The predicted fabric tensions were compared with the results of a
sliding block analysis, and show this simple analysis requires further
correlation...
Mass soil movements of four types; debris avalanche, debris torrent, debris slide and bank slough, were field inventoried in the Oregon Coast Range. A total of 104 mass movements were located in 21 undisturbed watersheds and 13 clearcuts harvested in the last six years. Failures associated with roads and landings...
During construction of the embankment at Blue River Dam
placement difficulties were occasionally experienced with the filter
zone sands. In the extreme condition construction equipment became
mired and part of the fill had to be removed and wasted. A
laboratory investigation was conducted on materials from the above
project to...
Combinations of cohesive and cohesionless soils are often encountered
when evaluating the engineering properties of soils. The
stress-volume characteristics of the mixed soil are found to vary according
to the proportion of each component. If the cohesive soil
composes more than a certain fraction of the material, the magnitude
of...
Nearly all soils are comprised of mixtures of coarse and fine particles. Behavior under mechanical and thermal loading of soil is strongly influenced (and in some cases, governed) by the ratio of coarse to fine particles. A better understanding of the fundamental behavior of soil mixtures will provide insight to...
