Skin Friction Distrtibutions on Piles in Sand
Presented in this paper are early results from an analytical investigation of the performance of a closed-ended pipe pile under monotonic axial loading in dense sand. The study was performed...
Review of API Guidelines for Pipe Piles in Sand
Most offshore structures are supported using steel pipe piles which are designed in accord with API Recommended Practice 2A. The guidelines for analysis of axial capacity of steel pipe...
Piles Under Dynamic Loads
This proceedings,
The Caisson Solution
Detroit is expanding its wastewater treatment plant to drastically reduce combined sewer overflows. The expansion, however, is being done on an extremely congested 4 acre tract of land...
Under the Undersea World
Soil conditions in New Orleans are generally unfavorable to the construction of large structures, and exceptionally so along the Mississippi River banks, which tend to slide. But that...
Cellular Sheet-Pile Floodwall
Williamson, W. Va., flooded 37 times in this century, will soon be guarded by a $41 million, 4000 ft floodwall being built by the U.S. Army Corps of Engineers. A series of 41 circular...
Single Pile and Pile Group in Permafrost
The results of laboratory and field experiments on single pile and pile group behaviour in frozen soils are reported. It was shown that the character of soil deformation was influenced...
Leachate Flow from an Experimental Fly Ash Landfill
Combustion of coal in large-scale utility boilers produces an ash by-product which is often stored in open landfills. An experimental fly ash landfill was constructed by Pennsylvania Power...
Fixing Foundations
Conventional underpinning or pilings are still the most common construction methods used to strengthen foundations, but new grouting techniques are giving engineers some fresh alternatives....
The Pressuremeter: Some Special Applications
The preboring pressuremeter has been used for foundation design for many years. Some recent developments are presented which extend the applications of the pressuremeter. These developments...
In Situ Determination of Smith Soil Model Parameters for Wave Equation Analysis
A methodology for in situ determination of Smith soil model parameters for wave equation analysis is presented. The method uses a small-rod penetration test in conjunction with CAPWAPC...
Expert System for Driven Pile Selection
Selection of driven piles for deep foundations is a complex process. Many subjective factors enter into the decision of which pile to select, making experience an important factor in proper...
Group Efficiency of Piles Driven Into Sands: A Simple Approach
A simplified analysis for computing group efficiency of circular displacement piles in sands is presented. Pile installation is assumed to cause soil displacements in the horizontal direction...
Three-Dimensional Nonlinear Study of Piles and Simplified Models
In a recent study the authors examined the effect of the nonlinear behavior of soil on the axial and lateral response of one or two piles due to monotonic and cyclic pseudodynamic loading...
Monte Carlo Simulations of the Dynamic Response of Pile Groups
A study is presented on the effect of variations of relevant parameters within a pile group on the vertical dynamic response of the group. These parameters include the shear wave velocity...
Modification of
The response of piles in a rectangular group subjected to lateral loading has been analyzed using a three-dimensional finite element model to evaluate the effect of pile spacing on lateral...
Group Effect in the Case of Downdrag
A summary of the various techniques available to calculate downdrag forces on pile groups is presented. In light of all these existing techniques, a simplified method is recommended. An...
Analysis of Geometric Mispositioning in a Vertical Pile Group
A straightforward procedure is described whereby an approximate, three-dimensional, nonlinear model for the analysis of pile groups is used to simulate errors in major group parameters...
Scour Around Cylindrical Piles Due to Wave Motion in the Surf-Zone
The paper discusses the results of experimental tests to study scouring phenomena around cylindrical piles during a sea storm with reference to the modelling of a beach profile in the...
Soil Nails as Temporary Powerhouse Support
Newcastle Powerhouse was constructed as an underground structure with its top deck at the finished ground surface. The powerhouse is three-quarter circular and one-quarter square in plan....
