Location of Geologic Discontinuities by Geophysical Techniques
An overview of the seismic refraction method and resistivity methods is given. These two geophysical techniques are integrated into a systematic method for locating geologic discontinuities...
Some Dilatometer Test Results in Pennsylvania and New York
This paper starts with a brief introduction to the dilatometer and piezoblade. Test results in four different areas are presented. DMT soundings at LR 67057 (Legislative Route numbers...
Identification and Characterization of the Collapsing Alluvial Soils of the Western United States
Suggested procedures for the identification and characterization of the collapsing alluvial fan, mudflow and debris flow deposits of the arid and semi-arid parts of the western United...
State-of-the-Practice Mitigation Measures for Collapsible Soil Sites
Mitigative alternatives for collapsible soil sites are reviewed considering shallow, as well as deep, collapsible soil deposits. In the case of deep soil deposits the overburden pressures...
Characterization of a Site Underlain by Deep Collapsing Soils
The geomorphic setting of a site underlain by an 80 ft (24 m) deep deposit of collapsing silty sand is described. The field and laboratory investigation completed to characterize the geotechnical...
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...
Jet Grouting for Underpinning and Excavation Support
Jet Grouting as a new tool for underpinning and excavation support is presented, describing the systems of Jet Grouting and its advantages over conventional underpinning techniques. A...
Effect of Site Soil Properties on Seismic SSI Response of Embedded Structures
In a series of two-dimensional soil-structure interaction (SSI) analyses, seismic responses, including the SSI effect of a deeply embedded reactor building of a standard plant in different...
Pile Foundation Construction Practice in Stiff Clays with Dense Granular Layers
A survey was conducted recently in conjunction with a project located in the San Francisco Bay Area to ascertain the general pile driving practice in stiff overconsolidated clays interbedded...
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...
Building on the Coastal Barriers Resource Act
In 1982, the Coastal Barrier Resources Act (CBRA) was enacted to minimize the loss of human life, wasteful expenditure of Federal revenues, and damage to fish and wildlife and other natural...
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....
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...
Environment Exploitation by Prehistorical Population of Rio De Janeiro
The specific purpose of this project was to establish the cultural contexts in the area being studied as well as to define the mechanisms of environmental manipulation that were employed...
The CADD Landfill
Designing landfills with CADD, engineers have reduced cut and fill calculations from two weeks to two days. Aerial surveys arrive on magnetic tapes and are loaded into computers by in-house...
Perceptions of Architects Regarding Use of Computers and Educational Requirements for Architectural Technicians
This paper identifies those cognitive competencies common to all CAD programs to determine which will best prepare the students for entry-level CAD proficiency and flexibility within the...
Monte Carlo Simulations of Uncertainties in Risk Assessments of Superfund Sites Using Crystal Ball?
Most health risk assessments for Superfund sites combine a series of worst case assumptions to derive a 'point estimate' of risk that is 'conservative,'...
Gamma Exposure from Rn Progeny in GAC Units
An investigation into the gamma exposure rate generated by granular activated carbon (GAC) water treatment units focused on ten sites that covered a range of source radon (Rn) in water...
Hazardous Waste Disposal: An Attitudinal Affront
Modern disposal facilities are thorough and conscientious in their methods. Environmentally sound practices are essential to protect the company and its clients from liability. The average...
The Application of Risk Assessment at Hazardous Waste Sites
This paper discusses some of the recent innovative uses of risk assessment at hazardous waste sites. Important developments in both methodology and application are as follows: quantitative...
