Seismic Analysis and Design for Soil-Pile-Structure Interactions
Pile foundations are used extensively to support structures in seismic regions around the world. For years, geotechnical engineers have neglected to consider the interaction soil-pile...
An Investigation of the Reinforcing Effect of Stone Columns in Soft Clay
A proposed major extension to an iron ore handling yard was located in an area underlain by soft alluvial clay. Stone columns were proposed to limit settlement of rails supporting the...
Load-Settlement Prediction of Footings on Steep Slopes
The use of spread footings on slopes is a common practice in the design of bridge foundations. Footings are generally constructed in the slope or at its crest to minimize the bridge length,...
Numerical and Centrifuge Modeling of an Arch Dam on Jointed Rock
This paper addresses the stability of an arch dam built on highly fractured argillite. A large concrete thrust block combined with a wing dam forms the left dam abutment. The last FERC...
Displacements in the Soil Near a Tunnel Face Using Centrifuge Tests and Image Processing
Image processing is applied to measurements of the soil for a tunnel model in centrifuge. For this aim a specifical device has been developed on the LCPC centrifuge (Nantes, France) and...
A Centrifuge and Analytical Study to Evaluate Suction Caissons for TLP Applications in the Gulf of Mexico
This paper documents the results of a combined centrifuge and analytical study to evaluate the behavior of steel suction caissons under loading and soil conditions typical of deepwater...
Experimental and Theoretical Dynamic Compliances of Foundations
An experimental study of the dynamic behavior of surface foundations on granular soils by centrifuge modeling is presented. The test method allows a direct measurement of the complex-valued...

Earth Pressure Acting on Buried Flexible Pipes in Centrifuged Models
Distributions of both normal and tangential earth pressures acting on three flexible model pipes having different wall thicknesses were successfully measured in centrifuge model tests....
FE Elastic Analysis of Measured Earth Pressure on Buried Rigid Pipes in Centrifuged Models
FE elastic analyses of earth pressure on buried rigid pipes yielded results that agreed well with the earth pressure measured in 42 centrifuged models, confirming both the reliability...
Artificial Gravity Research Facility Options
On a long duration manned mission to Mars, the physiological changes caused by microgravity may be counteracted by artificial gravity. This paper evaluates several different classes of...
Comparison of Centrifuge Performance on Oxygen Activated Sludge
This paper compares the performance of centrifuges processing high purity oxygen activated sludge with units processing conventional activated sludge. Comparisons are made both for thickening...
Improved Centrifuge Designs for High Cake Solids
The new generation of advanced centrifuges pioneered by Humboldt Wedag can readily produce 30 ? 2% TS cake on most raw and digested primary and waste activated sludge, wherein the primary...
Soil Properties Evaluation from Centrifugal Models and Field Performance
The performance of geotechnical projects is dependent upon the appropriateness of the design theory to the boundary conditions, and the characterization of the soil properties used in...
Consolidation of Slurried Soils
This paper describes the use of large strain consolidation theory and centrifugal modelling to study the consolidation behavior of slurries. Laboratory testing of the slurry is needed...
Centrifugal Modeling of Ice Forces on Single Piles
The ice forces and ice floe failure mechanisms associated with an ice sheet surrounding a vertical cylindrical pile were evaluated. A test system was developed to model ice forces in gravity...
Earth Pressure on Underground Rigid Pipe in a Centrifuge
A series of centrifugal model tests on underground pipes that simulate the actual construction process were carried out to investigate the earth pressure concentration onto the pipe (particularly...
Centrifuge Model Testing with Dynamic and Cyclic Loads
This paper examines the use of small-scale tests on centrifuges to study a wide range of problems in soil dynamics - including machine foundations, structures and explosion effects. The...
Selfweight Consolidation of Very Soft Clay by Centrifuge
This paper reports a series of selfweight consolidation tests and their analysis by Mikasa's consolidation theory. The tests covered a coastal reclamation project and the...
Validation of Consolidation Properties of Phosphatic Clay at Very High Void Ratios
The void ratio-effective stress and void ratio permeability relationships for phosphate slime mine tailings were measured by several methods. The measurements were used in nonlinear finite...
