Existing interpretation methods for axial uplift load tests are reviewed critically, and a qualitative and quantitative comparison is made for selected methods. A new method, which fulfills...
Interpretation of Load Tests and Drilled Shafts?Part 3: Lateral and Moment
Existing interpretation methods for lateral and moment load tests are reviewed critically, and a qualitative and quantitative comparison is made for selected methods. A new method is proposed...
Nondestructive Testing of Deep Foundations with Sonic Methods
Nondestructive testing and evaluation (NDT&E) of deep foundations with three sonic methods is discussed. Case history investigations described include test records from drilled...
Geophysical and Nuclear Methods for Non-Destructive Evaluation of Caissons
Non-destructive testing techniques were used to confirm the concrete integrity on the caisson foundations for the 45-story Ohio Corporate Headquarters building in Cleveland, Ohio. The...
Bearing Capacity of Shallow Strip Foundation on Strong Clay Underlain by Weak Clay
Laboratory model test results for the ultimate bearing capacity of shallow strip foundations supported by a stiff clay layer underlain by a weaker clay layer have been presented. The model...
Performance of a Large Ribbed Mat on Cohesive Soil
The performance of a 678-ft by 304-ft (207-m by 93-m) ribbed concrete mat was studied to provide improved soil input parameters for design. The mat was constructed on a low plasticity...
Bearing Capacity of Shallow Foundation on Granular Column in Weak Clay
Laboratory model tests results for the ultimate bearing capacity of shallow rectangular foundations supported by granular columns made in weak clay have been presented. In all cases, the...
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...
Issues in Evaluating Combined Repeated Loading of Deep Foundations
The capacity and load/displacement response of deep foundations subjected to combined modes of repeated loading can be significantly different from the response under single (axial or...
Pile-Drilled Caisson Combination for Foundation of High Rise Building
The analysis and evaluation of several alternatives for foundations of a high rise office building is presented, which resulted in the selection of a combination of high capacity piles...
Statistical Analyses of Drilled Shaft and Embedded Pole Models
In recent years a significant effort has been made by the Electric Power Research Institute (EPRI) to develop new design models, to collect and summarize existing load test data and to...
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...
Special Bedrock Conditions and a Foundation Project in Greater Boston
In the greater Boston area the argillite bedrock and/or the overlying glacial till provide suitable support for a wide range of foundation systems, including high capacity end-bearing...
A New Combined Footing and Drilled Shaft Foundation Design
A conventional belled caisson foundation installation in glacial till to support a suburban Chicago 10-story office building was stopped when test caissons revealed excessive water-bearing...
Design, Construction, and Load Testing of a High Capacity Caisson
This paper describes the large diameter caisson foundation for the upstream guidewall at the Lock and Dam No. 26 (Replacement) Project. The guidewall is supported on two rows of 6-foot...
Axial Capacity of Pressure-Injected Piles: A Cavity Expansion Model
The application of cavity expansion theory to the development of a mathematical model for predicting the ultimate axial capacity of pressure-injected piles in cohesionless soils is presented....
