Special Bedrock Conditions and a Foundation Project in Greater Boston
In the greater Boston area the argillite bedrock and/or the overlying glacial till provide suitable support for a wide range of foundation systems, including high capacity end-bearing...
Long Term Performance of High Rise Mat Foundation
The vertical movement of the foundation soils for a multi-story high rise office tower was monitored during foundation excavation, tower construction and the 25-year in-service period...
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...
Design, Construction, and Load Testing of a High Capacity Caisson
This paper describes the large diameter caisson foundation for the upstream guidewall at the Lock and Dam No. 26 (Replacement) Project. The guidewall is supported on two rows of 6-foot...
Underwater Foundations for a Jack-up Barge
Innovative underwater foundations were developed to provide a solid base for the legs of a large jack-up barge needed by General Dynamics to transport heavy components from Quonset Point,...
Axial Capacity of Pressure-Injected Piles: A Cavity Expansion Model
The application of cavity expansion theory to the development of a mathematical model for predicting the ultimate axial capacity of pressure-injected piles in cohesionless soils is presented....
Response of Concrete Island Drilling System to Ice Impact Loading
The lateral stability and load/deformation characteristics of the Concrete Island Drilling System structure under ice impact loading conditions were studied. The 300-foot-square (91.5-meter...
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...
Interaction of Geology, Construction Practice and Foundation Design
The influence of geologic knowledge and construction practices on the geotechnical foundation design process has been assessed and summarized. Particular emphasis has been given to the...
The Role of Analytical Geomechanics in Foundation Engineering
The role of modern geotechnical analysis in foundation design is reviewed, and analysis methods are classified into three categories, depending on their level of sophistication. The benefits...
Reliability in Foundation Engineering Practice
The value and use of reliability concepts in foundation engineering practice are explored, with a focus on two complementary approaches. In the first, macroscopic and action-oriented,...
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...
Dredge Disposal Monitoring by Fourier Shape Analysis
Fourier grain-shape analysis characterizes a population of sediments in terms of the shapes of the grains. The technique of grain-shape analysis has been successfully applied to the area...
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...
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...
Heavy Metals Pollution Monitoring Through the Critical Pathways Analysis: The Sepetiba Bay Case
The methodology of the critical pathway analysis has been widely employed to monitor the environmental impact of nuclear power plants in the aquatic environment. This methodology has been...
POU/POE Devices: Availability, Performance, and Cost
In order to gather and summarize information and data on point of use/point of entry (POU/POE) devices, a committee was established by the Environmental Engineering Division of the American...
Expert Systems for Assessment of Radon Gas
This paper covers a brief discussion of enviro-geotechnical aspects of radioactive toxic radon gas. Basic information required for assessment and controlling this gas is summarized and...
Occupational and Environmental Exposures to Radon: A Perspective for Mitigators
Occupational exposures to radon and radon decay products and the associated high incidence of radiation induced lung cancer form the basis for our present-day concern for limiting exposures...
