Large-scale experiments on circular model cell bulkheads were
conducted to define the distribution of hoop stresses, deflections of
the cells, distortion of the cell fill, ultimate overturning resistance,
and the critical mode of failure. The embedment depth of the model
cells was varied to investigate the effect of embedment on...
Plate loading tests in rock are deceptively simple tests to perform.
Consequently, many varieties have been developed in the past
60 years. From each of the varieties various investigators have added
their own developments and modifications, some good, and some not so
good. The result has been a confusion of...
Predetermining the ultimate capacity of piles driven into purely
cohesive soils and purely cohesionless soils involves, respectively,
the consideration of soil shear strength in a completely undrained and
a completely drained condition. For the intermediate cases concerning
soils that possess both cohesion and internal friction (silts, clayey
silts, sandy clays,...
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...
Expansive soils in Eugene, Oregon present a problem to
residents, consultants, contractors, and the city government. During
the years 1977 to 1979, the nature and extent of the problem was
identified, including an outline of the local occurrence of expansive
soils and possible engineering solutions to the most often encountered...
The strength of both undisturbed and compacted soils from 10 sites
in the slide-prone Tongass National Forest in SE Alaska were studied.
Index property tests were also conducted on disturbed samples. The
index tests included natural water content, Atterberg Limits, specific
gravity of solids, grain size distribution, and moisture-density relationship....
Settlement of structures built on geologically recent compressible alluvium is a common cause of concern during design. Total settlement results from a combination of: 1) initial elastic settlement, 2) primary consolidation, and 3) secondary compression. The reliability of prediction of total settlement is affected by an understanding of these components...
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...
Greenwashing is a relatively novel, diversely interpreted, and under-researched social phenomenon. Therefore, studying greenwashing concepts, methodological yardsticks, and the dynamic behind its pervasiveness provides an excellent opportunity to improve our understanding of it, refine our detection tools, and illuminate its influencing factors and impacts on society. This study aims to:...
