Geotechnical investigation: Cominco's Red Dog Mine Facilities
The siting of major facilities associated with development of the Red Dog Mine Complex in Northwestern Alaska on relatively warm permafrost soil and rock presented geotechnical engineers...
Permafrost: A Suitable Landfill Containment Barrier
Ice-rich permafrost is a suitable medium for the containment of wastes. The combination of frigid dry Arctic climate and the impermeability of ice-cemented permanently frozen ground can...
Innovative Solutions to the Challenges of Heavy Civil Projects
Each heavy construction project presents unique conditions and challenges. For large projects, the work scope may justify an extensive engineering analysis and significant investments...
Construction Insurance: An Alternative Unified Risk Insurance
The transfer of risk mechanism (insurance) can be applied to solve problems unique to the construction environment. The proposed program is worthy of support since all segments of the...
Design and Construction of the Spirit Lake Outlet Tunnel, Mount St. Helens, Washington
In 1982, a governmental task force was formed to evaluate the hazard posed by the blockage of Spirit Lake that resulted from the eruption of Mount St. Helens in May 1980. An analysis was...
Engineering Implications of Impoundment of the Indus River by an Earthquake-Induced Landslide
Historical records and physical evidence indicate that in the Himalayas of northern Pakistan a huge landslide dam was caused by an earthquake in 1840. The dam blocked the Indus River,...
Fault Diagnosis of Hazardous Waste Incineration Facilities Using a Fuzzy Expert System
The use of an expert system along with fuzzy fault tree analysis is discussed in connection with fault diagnosis of a hazardous waste incineration facility. This fault tree is a diagrammatic...
An Expert System for Inactive Hazardous Waste Site Characterization
The area of hazardous waste management is a broad and multidisciplinary field requiring expertise in engineering, geology, chemistry and toxicology, and is an ideal area for the application...
An Expert System for Site Selection
Site selection involves two phases. First, a small number of alternatives among all possible sites are identified for further evaluation, and then the selected alternatives are examined...
Applications of Automated Interpretation to Sensor Data
This paper focuses on potential applications of the AISD. (A knowledge-based concept for automating the interpretation of sensor data) concept in civil engineering. A number of potential...
A Salt Solution for Nuclear Wastes
The Department of Energy's Waste Isolation Pilot Plant in Southeastern New Mexico is the nation's first full-scale facility for disposing of radioactive waste...
Overcoming Opposition
During a zone change hearing in connection with site selection for a new landfill near Coeur d'Alene, Idaho, some honest communication overcame opposition by the residents....
Cleaning Up Toxics
Case histories show how several different types of contamination cleanup were handled. In Attleboro, Mass., washwater, used to decontaminate equipment and tools after cyanide was removed...
Fire on the Water
Incineration is a promising hazardous waste disposal technique. However, nobody wants an incinerator constructed near him, so waste handlers are considering burning hazardous wastes at...
Treatment in Your Own Backyard
Everyone wants the nation's hazardous waste sites cleaned up, but nobody wants the wastes disposed of near them. Therefore, cleaning up these problems at the site may be the...
Attapulgite: A Clay Liner Solution?
Poor performance of clay liners at waste management facilities has resulted in the EPA mandate of synthetic polymeric liner materials to comply with zero penetration requirements. Laboratory...
Risk Assessment: Engineering Tool
In factoring in human-health impacts when tackling an environmental problem, risk assessment is often the best approach. Its use is growing fast. The technique increasingly is being used...
Design of Wharf Facilities, Guam, M.I., to Accommodate Difficult Site Conditions
A wharf facility currently under construction in Guam, Mariana Islands, for the U. S. Navy utilizes precast concrete box caisson construction to satisfy difficult site conditions. To reduce...
Design and Construction of Marine Facilities for Ridley Island Coal Terminal
The design and construction of the wharf for 250,000 DWT bulk carriers is discussed in this paper. The terminal project was carried out on fast-track, 23 month schedule, with construction...
A Multi-User Fender Design and Installation
The increase in damage frequency to the existing Timber Fender System during the change-over from military to commercial/industrial users resulted in a call for design solutions from the...
