Compression Load Tests on Concrete Piles in Alluvium
A series of tests was accomplished during the design phase for the West Seattle Freeway Bridge Replacement project. The results of instrumented compression load tests in alluvial deposits...
Evaluation of P-Y Relationships in Cohesionless Soils
Four semi-empirical procedures for construction of p-y curves in cohesionless soils were developed to fit data from a particular load test or a specific set of tests on similar soils....
Evaluation of P-Y Relationships in Cohesive Soils
The practice of analyzing laterally loaded driven and bored piles often requires modeling of soil response in terms of uncoupled, non-linear unit load transfer functions. These functions,...
Pile Caps Subjected to Lateral Loads
This paper reviews current pile cap design practices and presents results of tests on two pile caps with different reinforcement locations. Lateral load tests performed on two pile cap...
Dynamic Stiffness of Pile Groups
A number of procedures have been proposed for the dynamic analysis of complete pile foundations including group effects. Most of these introduce some sort of approximation to reduce the...
Winkler Soil Model for Axial Response Analysis of Pile Groups
In this approach, the soil is idealized as a nonlinear Winkler model for a pile group attached to a group of piles. The model can account for pile-soil-pile interaction. Pile group responses...
The Simple-Pile Approach to Pile Installation in Clays
This article describes the fundamentals of the approach and presents solutions for the effects of quasi-static deep undrained penetration of a simple solid pile on the deformations and...
Pile Foundation Movements During Construction
Two case histories concern a shipyard wharf and work bay in Los Angeles harbor and an oil refinery expansion in Sumatra, Indonesia. The case histories provide further data on the nature...
Pile Foundation Design Using Pile Driving Analyzer
A case history of pile foundation design and construction for Pacific Bell's San Ramon Valley Administrative Complex is presented. Dynamic monitoring of driven piles with...
Role of a Standard in the Production of Drilled Shafts
The preparation of drawings and documents that describe the details of the installation of drilled shafts for a project requires an up-to-date standard. The role of the standard in the...
Geotechnical Perspective?Proposed Drilled Shaft Standard
In the writer's understanding, a standard is an agreed upon manual of practice and as such, sets the level of performance and attainment considered adequate. A standard is...
ASCE Drilled Shaft Standard: University Perspective
A critique is presented of the proposed ASCE standard on drilled shafts. Areas where major work is necessary relate primarily to the shaft design sections, establishment of loads, and...
Standards and the Contractor
The International Association of Drilled Shaft Contractors have written their own standards and have cooperated with other groups in similar activities. The author gives his ideas about...
Government Agency Perspective on Standard for Drilled Shafts
Relative to the proposed ASCE standard for Design and Construction of Drilled Shafts, the Tennessee Valley Authority (TVA) would be considered an 'owner'. However,...
Functional Specifications of a Distributed Engineering Data Management System
The development of a large-scale engineering data management system is outlined for AEC industries. Described are the outline specifications and basic design decisions used to implement...
Numerical Analysis of Two Embankment Foundations
Two case histories of the performance of a compressible embankment foundation are analyzed using the Cam-Clay constitutive model and a finite element consolidation program. The I-95 highway...
Logan Airport Re-Visited
The first detailed evaluation of self-weight consolidation of a large hydraulic clay fill was performed during the construction of Logan Airport in Boston nearly 40 years ago. The paper...
Consolidation of Permafrost upon Thawing
Methods of predicting initial consolidation upon thawing and the subsequent consolidation with time under increasing pressures are presented in terms of changes in unit weight. Procedures...
Dredged Slurry Stabilization for Seagirt Marine Terminal
The Seagirt Marine Terminal is constructed on reclaimed land on dredged spoil from the I-95 Fort McHenry Tunnel in Baltimore, Maryland. Three stabilization procedures considered applicable...
ASCE Salary Survey 1983
This is the seventeenth report in a series of biennial salary surveys conducted by the American Society of Civil Engineers. Salary data is reported on seven major categories for civil...
