Load Transfer in Deep Foundations Under Repeated Axial Loading
An analysis is presented of changes in axial load transfer for deep foundations under repeated loading, compared with static uplift and compression loading. Existing load test data demonstrate...
Numerical Modeling of Interface Behavior for Drilled Shaft Foundations Under Generalized Loading
To evaluate soil-foundation interaction numerically, an isoparametric thin layer element is used within a 3-D, material nonlinear, general purpose geotechnical analysis system developed...
Ultimate Capacity of Deep Foundation by a Rigid-Plastic Analysis
This paper is concerned with the determination of the axial ultimate capacity of a rigid pier on the basis of the theory of perfect plasticity. As an application of the upper bound theorem...
Nondestructive Testing of Deep Foundations with Sonic Methods
Nondestructive testing and evaluation (NDT&E) of deep foundations with three sonic methods is discussed. Case history investigations described include test records from drilled...
Geophysical and Nuclear Methods for Non-Destructive Evaluation of Caissons
Non-destructive testing techniques were used to confirm the concrete integrity on the caisson foundations for the 45-story Ohio Corporate Headquarters building in Cleveland, Ohio. The...
Issues in Evaluating Combined Repeated Loading of Deep Foundations
The capacity and load/displacement response of deep foundations subjected to combined modes of repeated loading can be significantly different from the response under single (axial or...
Backbarrier Beaches on a Developed Shoreline
The purpose of this paper is to identify the nature and magnitude of alterations to backbarrier environments on Island Beach Spit, NJ. This location was selected because it has different...
Barrier Beach Water Table Management
The solution to the water table elevation within a barrier beach, subject to the assumptions of a homogeneous and isotropic phreatic aquifer, is an ellipse with its long axis oriented...
Historical Shoreline Changes: A Comparison of Mean High Water and Vegetation Line Movement
A cooperative study produced historic mean high water shoreline change maps for the State of South Carolina. These maps have been used to calculate erosion rates for the entire developed...
Ponds and Lagoons of Gulf Islands National Seashore
A physical and natural resource survey was conducted of the ponds and lagoons on Horn and Petit Bois Islands, Gulf Islands National Seashore, Mississippi. Petit Bois Island contains 17...
Erosion and Washover in Coastal Louisiana
In 1985 three hurricanes affected the barrier coastline (Caminada-Moreau Headland) of Louisiana. These produced severe coastal erosion and rapid washover extension. Using the 1979 U.S.G.S....
The South Carolina Coast II. Development and Beach Management
The variety of development and conservation areas is superimposed on a wide range of erosion and accretion histories. Lack of construction setbacks has contributed to the general but probably...
A Review of the South Carolina Method for Establishing Coastal Setback Lines
The location of the setback line will depend to a large extent on the nature of the shoreline. Those areas adjacent to an unstabilized tidal inlet and affected by coastal processes at...
Input Management: A Proposal for the Largest Coastal Lagoon in Brazil
Principles of General System Theory and Energy Analysis are used to study the best management technique al Lagoa dos Patos (in southern Brazil), including its watershed and contiguous...
Low Cost Wave Measurement Program
This paper addresses some problems related to a wave measurement program in the coast emphasizing costs, environmental hazards and technological problems. Subjects covered include coastal...
Selection of Marine Bioindicators for Monitoring Radioactive Wastes Released from Nuclear Power Plants
The Brazilian Nuclear Program comprises the Angra I Nuclear Power Plant, in operational tests; the Angra II Nuclear Power Plant, under construction, expected to be completed in 1992; and...
Status of the Spiny Lobster (Crustacea: Palinuridae) Stocks Off Northeast Brazil in Relation to Fishing Effort and Environmental Conditions
Conditions for the development of relatively abundant populations of spiny lobsters of genus Panulirus, mainly P. argus and P. laevicauda, off Northeast Brazil are consistent with hydrologically...
Hydrobiological Characterization of Guanabara Bay
Guanabara Bay forms an ecological unity with serious environmental problems derived from an accelerated and unorganized process of urbanization without the necessary support. The UFRJ/Institute...
Vertical Distribution of Barnacles of the Intertidal Rocky Shores of Guanabara Bay, RJ, Brazil
This paper aims to give a quantitative analysis, using the belt-transect method, to describe the Balanomorpha species vertical zonation models of the intertidal in the rocky beaches of...
Management of Fisheries in the State of Rio De Janeiro, Brazil
To improve the interdisciplinary knowledge and to subdivide the problem in bio-ecological sectors, international committees recommend the development of integrated evaluation groups. On...
