Timber Pile Length Determination Using a Nondestructive Technique
Determining timber pile length is critical when evaluating the potential effects of scour and for determining pile capacity. Unfortunately, records of timber pile lengths are typically...
A program for the Analysis of Pile Load Tests
The load capacity of piles are routinely determined from full scale pile load tests under actual field conditions. Several empirical methods were proposed for the analysis of field load/settlement...
Estimating Sediment Relative Density Using an Impact Core Sampler and Wave Equation-based Pile Analysis
This paper presents a case history in which soil sample drive resistance was modeled with a wave equation-based pile analysis computer program to estimate in situ sediment relative densities...
Methods to Reduce the Settlement of Embankments on Soft Clay: A Review
New trends have been observed during the past ten years in the practice of settlement control for embankments on soft clays: they include increased use of rigid (piles) or semi-rigid (stone...
Deformations in Sand Layer During Pile Driving
This paper presents measurements of settlement and lateral soil movements in a medium dense to dense sand layer due to densification during driving of precast concrete piles. At one end...
Pile Settlement Based on Dynamic Measurements
Dynamic measurements during driving are well established for monitoring driving performance and the prediction of pile capacity. Post driving, signal matching office methods (e.g. CAPWAP)...
Static Pile Load-Movement From Dynamic Measurements
Static loading tests have traditionally been performed to determine the characteristics of pile load-movement relationships. Due to the expense involved and time required, this type of...
Numerical Study of Underpinning by Piles for Settlement Control of Strip Foundations
A numerical study has been carried out of a simple idealized problem of a shallow strip foundation (both flexible and rigid) on clay underpinned by rows of piles. The work is directed...
Design and Performance of a Piled Raft Foundation
The foundation system for a recently constructed building in Perth, Western Australia, consisted of combined pile groups and raft elements, with a total of 280 bored piles incorporated...
Displacement of Batter Piles in Layered Soil
The displacements of flexible vertical and batter model piles under eccentric and inclined loads in layered soil of clay overlying sand is studied. Horizontal and vertical displacements...
Down Drag on Friction Piles: A Case History
The down drag settlements experienced by the foundation of a supermarket constructed in 1972 in Gretna-New Orleans, Louisiana are presented. Two different lengths of piles (12.2 m and...
Design of Underpinning Piles to Reduce Settlements
Piles are frequently used to underpin structures which have suffered, or are expected to suffer, damage due to excessive settlement or differential settlement. However, existing methods...
Measured Downdrag on Seven Coated and Uncoated Piles in New Orleans
A site outside of New Orleans, Louisiana was selected as part of a research effort to study the phenomenon of downdrag on bitumen-coated piles. Two steel pipe piles, two timber piles,...
Comparison of Settlement Predictions for Single Piles in Sand Based on Penetration Test Results
The analysis of settlement for driven piles in cohesionless soils is a complex soil structure interaction problem. The total settlement for such a pile is generally considered to be the...
Modeling Settlements of an Existing Municipal Solid Waste Landfill Sideslope Using an Earthen Surcharge Pile
This paper discusses the results of a large-scale field compressibility test completed on municipal solid waste (MSW). The test consisted of surcharging the waste mass with an earthen...
Settlement Measurements of 50-ft High Embankments at the Chesapeake & Delaware Canal Bridge
This is a case history of instrumented settlement measurements on 49 to 56' (15-17 m) high bridge approach embankments of Delaware State Route 1 crossing of the Chesapeake & Delaware...
Measurements and Numerical Modelling of High Rise Building Foundations on Frankfurt Clay
Many high rise buildings were founded on Frankfurt clay on rafts applying average contact stresses in the order of 0.4 MPa. Beside rafts now piled-rafts are often used to reduce total...
Nonlinear Three Dimensional Analysis of Downdrag on Pile Groups
The downdrag on pile groups was investigated by using a numerical analysis and an analytical study. The emphasis was on quantifying the reduction of downdrag on piles in a group due to...
Settlement Prediction for Driven Piles and Pile Groups
Various methods of settlement prediction are reviewed for single piles and pile groups, and it is demonstrated that several of the methods give similar results. It is also found that the...
Settlement Analysis for 450 Meter Tall KLCC Towers
The site evaluation and settlement analysis performed for the two tallest buildings in the world currently under construction, are described. The site evaluation resulted in shifting building...
