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...
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...
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...
One of many important physical properties that must be known
to understand transport phenomena in soils is pore size distribution.
Presently the pore size distributions of soils are most commonly
obtained from soil water characteristic curves. The soil water characteristic
curves are usually obtained by the pressure plate technique.
It...
This paper examines the response of submerged model sand
slopes to vibration and the beneficial effects of placing rock revetments
on the face of the slope to prevent flaw slides.
Pore water pressure response and deflection were used as a
criteria for stability in an attempt to relate stability with...
This study was conducted to examine certain soil and hydrologic
properties of two major cohesionless soils Occupying 55% of the central
portion of the Oregon Coast Range. Knowledge of these properties was
desired to determine the role each played in the stability of slopes in
this region. Bohannon and Klickitat...
