Shaft Capacity of Driven Pipe Piles in Clay
A compilation of axial load test records for driven pipe piles in clay published by the American Petroleum Institute is analysed to yield new criteria for skin friction and pile scale...
Residual Stresses in Piles and the Wave Equation
A data base of 18 vertical load tests on driven piles in sand is presented. On average the residual point load was 56% of the measured point load and the residual friction load 19% of...
Vertical Behavior of Two 16-Year Old Drilled Shafts
Vertical load tests were performed on drilled shafts subject to lateral confining and heaving pressures from expansive soil over 16 years. Results indicated mobilized skin friction equal...
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,...
Lateral Load Tests of Piles in Sloping Rock Fill
A new container wharf constructed at the Port of Los Angeles features vertical prestressed concrete piles to provide both vertical and lateral support. A rockfill embankment used to allow...
A Flat-Dilatometer Study of Lateral Soil Response
The effect of flat dilatometer penetration on the lateral stress conditions in soil around the dilatometer blade and the soil response against dilatometer diaphragm deflection were investigated...
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...
Toward Interactive Color-Shaded Rendering in CAD
A software package (CATSIG) is described which allows the user to interactively color shade geometric objects created on a sophisticated commercial CAD system (CATIA). The novel features...
Advanced Graphical CAD System for 3D Steel Frames
An innovative, advanced graphical computer-aided design system, called STEEL-3D, is described. The main objective of this program is to provide the engineer with all the tools necessary...
Yield Behaviour and Consolidation. I: Pore Pressure Response
This paper discusses the frequency of occurrence of anomalous consolidation behaviour. The behaviour of soft clay is discussed briefly in terms of the effective stress path/yield envelope...
Yield Behaviour and Consolidation. II: Strength Gain
In Part I it was shown that in situ yielding of soft foundation clays significantly affected consolidation behaviour and that yield could be defined using the effective stress path/yield...
Instrumentation Performance in Soft Clay Soils (A Case History)
In 1978, IDEAL BASIC INDUSTRIES, INC. initiated construction of a cement manufacturing plant located south of Mobile, Alabama on the Theodore Ship Channel. Because deltaic clays were too...
Pavement Recycling: Stopgap or Remedy?
Recycled pavements cost less than new asphalt concrete overlays, but no long term data has ratified how recycled pavements' strength and durability compare to virgin material....
Effects of Fines in Gravel Bed Streams Behavior
A model-gravel bed stream is studied in the laboratory. Flow visualization of bedload motion correlates with bursting phenomena near the bed. The bedload variation as a result of the addition...
Pipeline Materials and Design
The proper use of pipeline materials and design is obviously paramount in the private and public works sectors. The introduction and proper use of new piping materials and design procedures...
Computer Aided Design in Civil Engineering
Increased application of computer aided design and drafting encouraged the organization of the symposium from which this book was derived. The papers presented at the symposium and included...
