Dynamic Soil-Pile Interaction Behavior in Submerged Sands

The Design and Construction of the San Francisco Southwest Ocean Outfall

Foundation Upgrading and Repair for Infrastructure Improvement
This proceedings, Foundation Upgrading and Repair for Infrastructure Improvement consists of papers presented at the poster session held in...

A Primer on Micropiles
A major study of micropile technology has recently been funded by the Federal Highway Authority and completed by the authors. The subject is defined as a drilled and grouted, cast-in-place,...

Monitoring of Structures During Repair of Underground Utilities
A collapse of underground utilities at a power plant required the constant monitoring of the surrounding structures during excavation and replacement of the damaged pipes. A computer-based...

High-Strain Kinetic Testing of Deep Foundations
High-strain kinetic testing involves the upward decelerating or accelerating of a mass and using its inertial force to axial prolonged pulse at the head of a pile. Currently available...

Low Strain Dynamic Testing of Wood Piles Supporting an Existing Pier
This paper presents a case history where low strain dynamic testing was performed to test wood piles supporting an existing structure. Under consideration is a 183 m long wooden pier constructed...

Some Aspects of Determination of Pile Capacity by the Wave Equation
This paper presents some new observations made during correlation study of pile capacity computed by wave equation analysis with failure load from static test. In order to determine proper...

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...

Preloading Organic Soils to Limit Future Settlements
This paper presents the authors' experience in preloading organic soils in south Florida to allow the construction of roadways, utilities, and low-rise residential structures on shallow...
