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...
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...
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....
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...
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...
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 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...
Consolidation of Mining Wastes
This paper describes laboratory and field tests for determining consolidation properties of soft sediments, presents data on several types of mining wastes, and presents the results of...
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...
Grouting Rehabs Earth Dam
To accommodate increased storage needs the Pennsylvania Power & Light Company had to reactivate a fly ash basin and raise an adjacent embankment dam. However, seepage through the...
Systems for Reducing Sedimentation in Berthing Facilities
Five systems are described which can be used to reduce sedimentation in harbor berthing areas. These systems, which are alternatives to conventional dredging, are based on either the resuspension...
Efficiency of Capping Contaminated Dredged Material
The ability of capping with sand to chemically and biologically isolate contaminated dredged material was investigated using large scale (250 l) laboratory reactor units. Tissue analyses...
Draghead Designs vs. Production
This paper discusses the development and design of draghead configurations for silt materials and describes a testing program designed to determine the most efficient range of the controllable...
Open Water Disposal for Marsh Creation James River, VA
There is a need for close cooperation between design and construction of levees on soft foundation for containing dredge material. The scope of this study included marine exploration,...
Implementation of EPA/Corps Site Evaluation Guidance
Past site evaluations have resulted in expensive and time-consuming field studies and a nationwide delay in final designation of interim sites. Recognizing the problem, a joint Corps/EPA...
Fabric-Reinforced Dikes, Craney Island
Three fabric-reinforced test sections 300-, 400-, and 750-ft long were successfully constructed on very soft dredged material deposits within the Craney Island dredged material disposal...
Dredged Material Disposal Modeling - Chesapeake Bay
A plan to deepen the approach channels to Baltimore Harbor from 42 feet to 50 feet involves in part the overboard disposal of about 9. 5 million cubic yards of dredged material in the...
