Sonoma County: Success Story of California's Coastal Development
The Sea Ranch second home development, agricultural and timber land preservation, the need for better commercial fishing facilities, and recreational and visual access to the coast were...
Unique Installation Methods for Large Interceptor in Poor Soil Conditions
The construction of approximately 1. 5 miles of a major sewer interceptor in downtown Boston encountered some unique construction challenges. The entire route required dewatering during...
Instrumentation for an Uplifting Ice Force Model
Pile-supported, light duty structures are especially vulnerable to the uplifting forces. To evaluate the parameters that control the magnitude of the uplifting force a laboratory model...
Design of Guideway Substructure Dada County METROMOVER
This paper describes the procedures and parameters used for the design of the guideway substructure for the Dade County METROMOVER system. The substructure for this work is defined to...
Summary Evaluation of Dade County's APM Foundations
This paper presents an overview of the engineering performance and cost effectiveness of the guideway and station foundations of Dade County's Automated People Mover (APM)....
Foundation Design Considerations for Detroit DPM
The design loadings for support of the elevated guideway of the Detroit Downtown People Mover (DPM) consist of high vertical as well as horizontal loads. In order to simplify foundation...
Redecking with Precast Keeps Traffic Moving
The Woodrow Wilson Memorial Bridge in Washington, D.C. could not be closed to traffic while a new deck was constructed. The engineers designed a precast prestressed and post-tensioned...
Coefficient of Variation of In Situ Tests in Sand
For a research project on the behavior of piles in sand for the United States Geological Survey and the Federal Highway Administration, ten sites were selected where detailed load tests...
LAX Takes Flight for the 1984 Olympics
LAX (the Los Angeles airport) had over two dozen contractors working on site to complete their $700 million improvement plan in time for the Olympics in July. They also came up with several...
Seismic Design for Highway Bridge Foundations
This paper focuses on the determination of stiffness characteristics of piles and pile groups. Both battered and vertical pile groups are considered. Recommended methods for determining...
Dome
Roofed with the worlds largest diameter wood dome at 530 ft., the Tacoma Dome, a multi-purpose sports and convention center has helped revitalize a blighted part of that Washington state...
Retaining Wall
The foundation of this off-ramp in Manchester, New Hampshire is made up of end-bearing piles and sloping rock anchors�an innovation that is unique to the United States. End bearing piles...
Finite-Strain Axial Analysis of Piles in Clay
In the late 1970's, a series of research projects developed simple effective-stress methods to predict the axial capacity of piles in normally-consolidated clay. The method...
Centrifugal Modeling of Pile Foundations
Modeling of pile foundations in a centrifuge, where the self weight induced stresses in the soil are simulated by elevated gravity loading, is described. Hollow pipe piles in a stiff clay...
Prediction of Settlement of Single Piles in Clay
Analyses by trial were used to fit theoretical load-settlement curves to measured curves for driven piles. For the elastic method, analyses of load tests indicated that designers should...
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...
Limiting Tip and Side Resistance: Fact or Fallacy?
The tip and side resistances of deep foundations do not reach a limit at a critical depth; instead, they increase with depth. For the tip, the rate of increase decreases with depth. For...
Cyclic Degradation of Pile Performance in Calcareous Soils
Laboratory data on the skin friction of jacked or driven model piles is presented. Significant cyclic degradation of skin friction commences when the cyclic displacement amplitude reaches...
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...
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...
