University of Florida Pile Capacity Prediction

Prediction of Pile Capacity

Efficiency and Vibration Testing
To gather the necessary data to assure the most efficient and reliable operation of the system, Idaho Power Company implemented a plant testing program in 1988. The testing program consists...

Update: Ozark-Webbers Falls Turbines
The Ozark and Webbers Falls powerhouses were designed and constructed under the supervision of the U.S. Army Corps of Engineers. Both are located on the McClellan-Kerr Arkansas River Navigation...

Tunnels and Vertical Shafts for Pumped-Storage
Economic considerations are of primary importance to the planning and designing of pumped-storage in an electrical generation and distribution system. This paper deals with the optimum...

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...

A Lateral Load Test on Seven Foot Diameter Caissons
Seven foot (2.1 m) diameter caissons (drilled shafts) were designed to support a mainline eastbound bridge and an off-ramp of Interstate Highway 70 in Glenwood Canyon, Colorado. A lateral...

Drilled Shafts—A Database Approach
A database of 43 drilled shaft load tests of high quality has been developed to study parameters that affect the axial behavior of drilled shafts and methods of analysis to predict axial...

Interpretation of Load Tests on Drilled Shafts—Part 1: Axial Compression
Existing interpretation methods for axial compression load tests are reviewed critically, and a qualitative and quantitative comparison is made for selected methods. A simplified method,...

Numerical Modeling of Interface Behavior for Drilled Shaft Foundations Under Generalized Loading
To evaluate soil-foundation interaction numerically, an isoparametric thin layer element is used within a 3-D, material nonlinear, general purpose geotechnical analysis system developed...

On the Critical Relative Displacement of Pile Shaft and Surrounding Soil
Model pile pull-out tests have been conducted to investigate the characteristics of the critical relative displacement at which the critical pile skin resistance is mobilized. Test results...

Interpretation of Load Tests on Drilled Shafts—Part 2: Axial Uplift
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...

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...
