A Use of Geostatistics to Predict the Occurrence of Collapsing Soils
Collapse susceptible soils are those that are stable under load while they are dry, but undergo large decreases in volume virtually instantaneously, when they become wetted to near saturation...

Design Methodology for Foundations on Stone Columns
Stone columns offer the geotechnical engineer a valuable and viable technique for stabilizing sites underlain by soils ranging from soft clays to loose silty sands. A discussion of the...

Consolidation Grouting Operations for Kirkwood Penstock
Kirkwood Penstock, which is part of the Hetch Hetchy water system of the City of San Francisco, California exhibited evidence of settlement and local extension following extraordinarily...

Modelling of Displacement Piles in Sand Using a Pressure Chamber
This paper describes a method of modelling the driving and loading of piles in the laboratory that permits variations of significant parameters and maintains effective stresses at levels...

Seismic Response Considerations in Foundation Design
There are no generally accepted procedures to determine the potential magnitude of reduction of footing bearing capacity that may result from soil strains or pore pressure changes during...

Bearing Pressure?SPT Correlations for Expanded Base Piles in Sand
Design of enlarged base piles is usually carried out using correlations between SPT N values and point resistance. The results of full scale load tests are used to show that base resistance...

Performance of Different Retention Systems in Similar Soils
Performance behaviour of three deep braced excavations in a similar soil profile, in the Chicago area is described. At each site, different bracing systems were utilized. Methods used...

Evaluation of a 50-Year Old Barge Dock on the Missouri River
The installation of a large crane on an existing barge dock on the Missouri River in Kansas City, Kansas required an evaluation of the dock system stability. The dock was constructed of...

Complex High-Rise Foundation Design and Construction
The substructure design and construction of a 60 story office tower in downtown Chicago is described. The presence of existing belled caissons on hardpan required use of filtered dewatering...

Thoughts on the History and Current Practice of Foundation Engineering in North America
With the publication of 'Erdbaumechanik' in 1925, the behavior of soils was explained in terms of numerical physical properties and the principles of what became...

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...
