Hydrodynamic Isolation of Concrete Dams
The feasibility of reducing hydrodynamic effects in the earthquake response of concrete dams by anchoring gas-filled balloons or injecting bubbles in the water is investigated. Significant...
Site Characterization of Yorktown Formation for New Accelerator
The design of a new 1700-m long continuous-wave electron beam accelerator facility (CEBAF) in Newport News, Virginia demanded an extensive geotechnical exploration program be conducted...
Pressuremeter Evaluation of Glacial Till Bearing Capacity in Toronto Canada
Glacial tills were evaluated at three Toronto sites, using conventional methods, the pressuremeter and full scale caisson load tests. The geologic environment and specific subsurface conditions...
Screw Plate Test for Drained and Undrained Soil Parameters
This paper describes a screw plate test device developed with a capability to measure the generation and dissipation of excess pore water pressure during testing in cohesive soils. The...
Some Dilatometer Test Results in Pennsylvania and New York
This paper starts with a brief introduction to the dilatometer and piezoblade. Test results in four different areas are presented. DMT soundings at LR 67057 (Legislative Route numbers...
An Evaluation of Pile Design in Fraser River Delta Using In-Situ Tests
Modern methods of pile design often take advantage of in-situ test data. Thirteen axial pile capacity design methods have been evaluated using the results from eight full-scale pile load...
Collapsible Soils in the Antelope Valley�California
Soils subject to hydroconsolidation, commonly referred to as collapsible soils, have a potential to undergo significant volume reductions upon wetting, with or without additional loading...
State-of-the-Practice Mitigation Measures for Collapsible Soil Sites
Mitigative alternatives for collapsible soil sites are reviewed considering shallow, as well as deep, collapsible soil deposits. In the case of deep soil deposits the overburden pressures...
Design Methodology for Foundations on Stone Columns
Stone columns offer the geotechnical engineer a valuable and viable technique for stabilizing sites underlain by soils ranging from soft clays to loose silty sands. A discussion of the...
Consolidation Grouting Operations for Kirkwood Penstock
Kirkwood Penstock, which is part of the Hetch Hetchy water system of the City of San Francisco, California exhibited evidence of settlement and local extension following extraordinarily...
Modelling of Displacement Piles in Sand Using a Pressure Chamber
This paper describes a method of modelling the driving and loading of piles in the laboratory that permits variations of significant parameters and maintains effective stresses at levels...
Seismic Response Considerations in Foundation Design
There are no generally accepted procedures to determine the potential magnitude of reduction of footing bearing capacity that may result from soil strains or pore pressure changes during...
Analysis of Pile Load Tests at Lock and Dam 26
This is a summary of the results collected during the extensive load test program performed by the U.S. Army Engineer District, St. Louis, during the construction of the new Lock and Dam...
Bearing Pressure?SPT Correlations for Expanded Base Piles in Sand
Design of enlarged base piles is usually carried out using correlations between SPT N values and point resistance. The results of full scale load tests are used to show that base resistance...
Performance of Different Retention Systems in Similar Soils
Performance behaviour of three deep braced excavations in a similar soil profile, in the Chicago area is described. At each site, different bracing systems were utilized. Methods used...
Interpretation of Instrumented Driven Steel Pipe Piles
This paper presents the results of a series of studies on the behavior of driven close-ended steel pipe piles. Extensive field explorations and geotechnical analyses have been carried...
Cost Effective Pile Foundation Supports Fast Track Paper Mill
This paper decribes the generalized subsurface conditions, pile evaluation and load test program, pile and piling contractor selection, production pile installation, and quality assurance...
Evaluation of a 50-Year Old Barge Dock on the Missouri River
The installation of a large crane on an existing barge dock on the Missouri River in Kansas City, Kansas required an evaluation of the dock system stability. The dock was constructed of...
Complex High-Rise Foundation Design and Construction
The substructure design and construction of a 60 story office tower in downtown Chicago is described. The presence of existing belled caissons on hardpan required use of filtered dewatering...
Thoughts on the History and Current Practice of Foundation Engineering in North America
With the publication of 'Erdbaumechanik' in 1925, the behavior of soils was explained in terms of numerical physical properties and the principles of what became...
