Displacements in the Soil Near a Tunnel Face Using Centrifuge Tests and Image Processing
Image processing is applied to measurements of the soil for a tunnel model in centrifuge. For this aim a specifical device has been developed on the LCPC centrifuge (Nantes, France) and...
Heavy Aircraft Damage to Rigid Airport Pavements
A theoretical solution is presented for the damage caused by heavy aircraft at the transverse joints in a rigid airport pavement. Large stresses in the subgrade generate significant permanent...
Drilled Shaft Side Resistance in Clay Soil to Rock
An evaluation is made of available field load test data for the axial side clay soils to hard rocks. Conventional total stress interpretations by the alpha method are used to examine the...
Load Testing of Permanently Cased Drilled Shafts Founded in Hartford Shale
The axial and lateral load testing of three, 30 inch (76cm) diameter, permanently cased drilled shafts is analyzed herein. The prototype shafts were founded in (or on) Hartford Shale bedrock,...
Perimeter Load Transfer in Drilled Shafts in the Eagle Ford Formation
Results of six full-scale compression loading tests at four sites in the Dallas area are considered. Compressive strengths (qc) of the rock varied...
Side Resistance of Drilled Shafts in the Denver and Pierre Formations
Results of load tests on drilled shaft foundations in Upper Cretaceous shales are described and evaluated. Three load tests were conducted on shafts in the Denver Formation, in Denver,...
Behavior of Instrumented Model Piers in Manufactured Rock with a Soft Layer
A laboratory test apparatus has been used to study the side resistance of piers socketed into manufactured soft-rock masses. The results of four tests are reported, three of which included...
Negative Skin Friction Due to Wetting of Unsaturated Soil
A steel building at a cement plant un Utah was originally supported by spread footings. Shallow wetting of the coarse granular soils supporting the footings resulted in over three inches...
Osmotic Suction as a Valid Stress State Variable in Unsaturated Soil Mechanics
The hypothesis of the research being presented is that the osmotic suction of soil pore fluid is an independent, valid stress sate variable for unsaturated soils. A review of concepts...
The Transistor Psychrometer: A New Instrument for Measuring Soil Suction
The transistor psychrometer is the latest instrument available for the measurement of soil moisture suction. It has been developed over a number of years and is very similar in operation...
Performance of Horizontal and Vertical Barriers
Horizontal and vertical barriers have been used on transportation facilities to control expansive soils and minimize their damages. The effort is to minimize moisture change in the soil...

Featured bridges are: Briggs Bridge (AK); Stone Arch Bridge (NY); Rio Grande Gorge Bridge (NM); Bridge Street Bridge (MI); Hennepin Avenue Bridge (MN); Egypt Pike Bridge (OH); William...
In-Service Durability Evaluation of Armourstone
A summary flow diagram for rock evaluation, general to all rock types and engineering applications of rock is introduced. It is then applied to armourstone. Increasing detail within this...
Laboratory Testing of Stone for Rubble Mound Breakwaters: An Evaluation
The quality of the final stone product hinges on the combination of two factors - rock properties and environmental conditions. The environmental conditions associated with production...
Physical Model Testing of Broken Armor Stone
Cracking, breaking into two or more pieces, flaking, crumbling, and abrading may reduce an armor stone to a size where wave action can remove it from the structure causing a local instability....
U.S. Experience With Armor-Stone Quality and Performance
In the past 30 years problems with deterioration and cracking of armor stone in the United States have been concentrated in northern regions, particularly around the Great Lakes. The explanation...
