An Unknown-Unknown Does In An Overpass: A Soil Stockpile on Soft Clay Is Too Much for a Bridge in Canada
Like most structures, bridges are designed for an array of loading conditions. Some loads are known or can be reasonably estimated with confidence (i.e., known-knowns, such as structure dead and vehicular...

Elegant Interchange for Tight Urban Spaces
The Seventh St. underpass, which opened in May of 1987, is a multilevel uban interchange crossing I-10 in the center of Phoenix, Arizona. With little right of way available, the interchange...
Stability of Armour Layers in Rivers
The importance of both the overpassing and the embedding of river bed particles is demonstrated by experiments. When a single layer thick armouring layer of uniform d1...
Climatological Estimates of Evapotranspiration
Interactions between evaporating surfaces and the overpassing air suggest that potential evaporation responds in a complementary way to changes in the availability of water for evapotranspiration...
Particle Overpassing on Flat Granular Boundaries
Sand-sized sediment under certain boundary shear conditions may overpass, i.e., may move as bed load, across a loose, flat boundary of unlike size and density without being deposited,...
Treat on a 120-ft-Span Prestressed Concrete Beam
Tests to destruction of 120-ft-span prestressed concrete beam similar to beams to be used in 4-span overpass at Chiswick, Great Britain; at ultimate load beam failed by crushing of concrete...
