Drilling with Direction
Norfolk, Va.'s 48 in. diameter raw water main crosses three rivers in its 52,000 ft route. At the Elizabeth River, an aerial or subaqueous crossing was not feasible, so a...

Drilled Shaft Friction Evaluation via Pullout Tests
The history, development, and field test results of a small-scale 'pullout' test to assess the skin friction (fsu) for drilled shafts socketed in...

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...

Bi-Directional Load Testing of Shafts to 6000 Tons
This paper describes the use of Osterberg cells (O-cells) to perform bi-directional load testing on full size production drilled shafts for a major bridge foundation near Owensboro, Kentucky....

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,...

Airport Towers: A New Generation
Airport control towers are a unique building type with monumental significance, both for the cities that own and operate the airports, and for the FAA which owns and operates them. Airport...

Feasibility Study of Petroleum Development in the Ross Sea, Antarctica
This paper discusses the viability of Antarctic petroleum development and estimates when Antarctic oil production could become economically feasible. The analysis is based on a hypothetical...

Dynamic Response Characteristics of Jack-Up Drilling Units
The effects of five parameters on the dynamic amplification of the global base shear on a deep water jack-up drilling unit were analyzed using a time domain nonlinear model. The five parameters...

Manholes and Microtunneling
Contractors are for the Oakwood Beach Interceptor Sewer Project, on Staten Island, N.Y., were having difficulty. Glacial tills and a high water table made working 90 ft below the ground...

Progress and Developments in Dam Rehabilitation by Grouting

Recent Progress in American Pinpile Technology

Naval Pier Foundation Design and Construction, Pearl Harbor, Hawaii
The paper presents a case study of foundation design and construction for a pier in Pearl Harbor. The study covers a review of site investigations, laboratory testing, pile selection and...

Geological Mappability of Bored Versus Drill and Blast Excavations for Radioactive Waste Repositories

Mass and Energy Tradeoffs of Axial Penetration Devices on Lunar Soil Simulant
Axial penetration of the lunar surface was performed to collect soil samples with drive tubes and drill cores on the six successful Apollo missions. Although the pile-driving and drill...

The Transport and Fate of Drilling Muds
The disposal of drilling muds from offshore oil platforms is of concern because of the potential effects of pollution from these muds. Both drilling muds and fine-grained bottom sediments...
