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...
A Laboratory Procedure for Partial-Wetting Collapse Determination
Partial wetting results in partial collapse, which is linked to the reduction in soil suction caused by wetting. The laboratory procedure presented in this paper represents a modification...

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...
Service Records of Chicago District Breakwater Stone and How These Relate to Test Results
Breakwater stone production is limited to areas with geologic outcrops capable of producing large rocks. The most reliable breakwater stone is that which exhibits the highest degree of...
Quartzite?A Hard Rock Approach to Rubble Mounds
The quality of stone in rubble mound structures has always been a concern but seems to be more so the past few years. Breakwaters built in the 1920's using granite armour...
Quarry Inspection: A Geological Perspective
The need to use durable rock in building projects is becoming more critical as the costs of labor and materials rise. The Steering Committee of the 1991 Quarried Rock For Rubble Mound...
