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
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...
Landslides are frequent in the steep forested regions of the Oregon
and Washington coastal mountain ranges. The need for forest products
has resulted in increasing logging activity in these marginally stable
areas. The occurrence of landslides has increased, which in turn has
focused greater interest in slope stability management.
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
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...
