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...
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.
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...
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...
Oregon's forestry industry has and will continue to be a vital component of Oregon's economy, with twenty-two percent of Oregon's 1986 gross state product and thirty-nine percent of Oregon's 1986 gross manufacturing product related the forestry goods. An integral component to proper management of Oregon's forestry lands is Sustaining the...
The logarithmic-spiral (log-spiral) limit equilibrium procedure for slope stability analysis rigorously satisfies both force and moment equilibrium with a failure surface geometry formulated as a function of the soil’s angle of internal friction. Within the framework of limit equilibrium, this procedure has, in the past, been primarily limited to homogeneous...
Straw wattles are common erosion control devices used to trap sediment. This
thesis studies the relationship of straw wattles on slope stability through a case study
demonstrating their use on steep slopes (1.5H:1V) for the US20 highway realignment
project. Several surficial slope failures have occurred on these fill slopes, often...
