Uncertainties in Offshore Axial Pile Capacity
The overall bias and error associated with the API recommended procedures and other popular methods for offshore pile design are evaluated. The paper considers single axial friction piles...
Risk Correction Factors for Bearing Capacity Analysis
In this paper bearing capacity correction factors are developed to account for the randomness in the load and soil properties. These are applied to the bearing capacity equation in the...
Movement Control of Excavation Support Systems by Iterative Design
Conventional design practice for excavation support systems emphasizes determination of loads and selection of structural components. This paper presents a method which uses movement control...
Some Expert System Applications in Geotechnical Engineering
Knowledge-based expert systems (KBES) represent a new technology for computer-aided engineering. These systems can be useful in situations which involve expert judgments for effective...
Augered Cast-in-Place Piles
Development of the augered cast-in-place pile system from origination in the late 1940's to the present state of the art is presented, with methods of pile placement, including...
Contribution of Soil Freeze to Pile Capacity
In order to investigate the magnitude and rate of increase in load capacity for piles installed in clayey soils, a series of load tests were performed at various intervals of time following...
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...
Effect of Void on Footing Behavior Under Eccentric and Inclined Loads
The effect of underground void on the behavior of strip footings subjected to eccentric and inclined loads was investigated using the finite element method of analysis. Results of the...
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...
Field Performance of a Soil Nail System in Loess
This paper presents data from measurements of a soil nail system constructed in loess soil in Pullman, Washington. The soil nail system is designed to retain a 39.2 ft (11.9 m) high excavation...
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...
Analysis of Drilled Shafts in a Deep Fill
A deep fill of varying thickness will settle with time and will also exhibit a horizontal component of movement. Drilled shafts that are installed in the fill to support a structure must...
Performance of a Building Foundation Designed to Accommodate Large Settlements
The Eastern Airlines shuttle terminal at LaGuardia Airport in New York City is supported on spread footings founded in an incinerated refuse fill which overlies a deep deposit of slightly...
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...
Sensitivity Study of the Cyclic Axial Capacity of a Single Pile
Evaluation of the axial capacity of an offshore pile subjected to a severe North Sea storm is presented. Effects of using different degradation criteria, upper and lower bound interaction...
Underwater Foundations for a Jack-up Barge
Innovative underwater foundations were developed to provide a solid base for the legs of a large jack-up barge needed by General Dynamics to transport heavy components from Quonset Point,...
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...
The Role of Analytical Geomechanics in Foundation Engineering
The role of modern geotechnical analysis in foundation design is reviewed, and analysis methods are classified into three categories, depending on their level of sophistication. The benefits...
