Design Charts for Piles Supporting Embankments on Soft Clay
Publisher: American Society of Civil Engineers
Abstract: This paper describes the development and application of design charts for piled embankment designs. It outlines the computational approach adopted, the geotechnical profiles used, and the application of the design procedure ...
Analysis of Residual Stress Effects in Piles
Publisher: American Society of Civil Engineers
Abstract: A simple method is outlined for analyzing the residual stresses in a single pile following driving or jacking and for determining the subsequent axial load‐deformation behavior. It is found that the stiffness of the pile ...
Cyclic Stability Diagram for Axially Loaded Piles
Publisher: American Society of Civil Engineers
Abstract: This paper develops the idea of a cyclic stability diagram in which the mean and cyclic axial loads on a pile are plotted and three regions are identified: (1) A stable zone in which cyclic loading has no effect on pile ...
Closure to “<i>Analysis of Residual Stress Effects in Piles”</i> by H. G. Poulos (March, 1987, Vol. 113, No. 3)
Publisher: American Society of Civil Engineers
Downdrag Forces in Group of Piles
Publisher: American Society of Civil Engineers
Abstract: This paper describes a boundary element analysis for analyzing the behavior of a group of end‐bearing piles subjected to negative friction. It is found that group effects lead to a reduction in downdrag force in a pile, ...
Analytical Prediction for Tunneling-Induced Ground Movements in Clays
Publisher: American Society of Civil Engineers
Abstract: Current design practice to predict tunneling-induced ground movements is generally based on empirical methods that are subjected to some important limitations. For a ground deformation prediction due to tunneling to be ...
Pseudostatic Approach for Seismic Analysis of Single Piles
Publisher: American Society of Civil Engineers
Abstract: This paper evaluates a simple approximate methodology for estimating the maximum internal forces of piles subjected to lateral seismic excitation. The method involves two main steps: computation of the free-field soil ...
Simplified Method for Design of Underpinning Piles
Publisher: American Society of Civil Engineers
Abstract: Existing buildings sometimes experience excessive settlement under their design load or face the prospect of excessive settlement in the future if a change of building use is required and increased foundation loadings will ...
Tests on Model Instrumented Grouted Piles in Offshore Calcareous Soil
Publisher: American Society of Civil Engineers
Abstract: This paper describes the results of tests on model instrumented grouted pile shafts installed into beds of an offshore calcareous sand. This calcareous sand was obtained from the North‐West Shelf of Australia, at the site ...
Effective Stress Dependence of Pile Shaft Capacity in Calcareous Sand
Publisher: American Society of Civil Engineers
Abstract: A series of model tests on grouted pile shafts in reconstituted calcareous sand is reported, in which the effective stress state is controlled by altering the back pressure in the soil and keeping the total pressure constant. ...
