Simulation of Leachate Discharge from a Small Island into a Tidal Bay
A small island in a tidal bay was considered as a potential site for depositing large volumes of excavation material from a transportation project. The island is located in the inner part...
Risk-Based Decision-Making Regarding Mixed Waste Disposal Systems
An efficient approach has been developed for making rational and defensible decisions among a variety of 'options' (e.g., remedial actions, engineered barrier...
Who Pays for the Unexpected in Construction? A Heavy Construction Contractor's Viewpoint
The complex question of who pays for the unexpected in construction is analyzed using several examples from experience. In addition to the unexpected being due to subsurface conditions,...
Where Does Rock Begin Beneath Philadelphia?
Philadelphia provides an excellent example of the engineering problems associated with the interpretation of saprolite/weathered rock/sound rock profiles. The bedrock beneath the city...
Foundation Studies in a Fault Zone and a Steep Valley Slope
This paper presents two case histories which illustrate unique problems in defining the character of rock for support of structures. The first case study concerns a conventional building...
Soil-Rock Transition Zone: Uncertainties for Design and Construction
This paper addresses the problem of establishing definitions of the soil-rock boundary with regard to different engineering applications in the Piedmont geologic provinces. Three engineering...
Rock in the Limestone Regions of the Southeastern United States
Problems often arise in the shaft drilling industry in the Southeast. The karst areas in this region have certain situations found in few other places. Erratic boulders and limestone pinnacles...
Determination and Presentation of Subsurface Conditions for Design and Construction
A major problem in the design and construction of many engineering projects is the lack of adequate geotechnical information both for design and for determining conditions to be encountered...
Subsurface Pavement Structure Inventory Using Ground Penetrating Radar and a Bore Hole Camera
The Pavement Management System (PMS) is now a necessary pavement evaluation tool. The PMS data base has been historically fed with surface inspection data, but increasing demands for accurate...
Innovative Breakwater Designs on the Great Lakes
Extensive investigations have recently been undertaken to support the development of rubblemound breakwater designs for new marinas at Kenosha and Sheboygan, WI, both located on the west...
Pavement Design for the New Denver International Airport
Denver International Airport is the first new major U.S. airport in twenty years. Primary airfield elements in Phase I development include 5-12,000 foot runways and 1-16,000 foot runway,...
Analyzing Risk
Engineers designing major projects must often grapple with large areas of uncertainty�from estimating the seismic hazard to a nuclear powerplant to the potential effects of decades of...
Analysis of Earthquake Response at a Site With Uncertain Properties
The problem of earthquake response of a soil deposit with uncertain properties is studied in the paper. Various analysis procedures for handling the dynamic response of an uncertain system...
Development of Transportation Operations Requirements: Operations Planning
Transport conditions at various utility sites vary dramatically in terms of characteristics at and near the site, requirements, administrative procedures, and other factors. Continuation...
Development of Rail Access to the Yucca Mountain Site: Technical and Publc Issues
The Yucca Mountain site, located on the southwestern edge of the Nevada Test Site (NTS), is an undeveloped area under investigation as a potential site for high-level nuclear waste (HLW)...
PAGIS & PACOMA: Performance Evaluations of Deep Geological Disposal. Results and Conclusions
Two coordinated research projects were undertaken by the Commission of the European Communities to study the safety performances of geological radwaste disposal systems in the post-operational...
Performance Assessment at the NRC: Current Issues and Recent Progress
Performance assessment plays a major role in the NRC's licensing program for the disposal of high-level radioactive waste. Planned and recent performance assessment activities...
Container Material Selection, Modeling and Testing
Virtually all of the approximately 40,000 high-level nuclear wast containers to be emplaced at Yucca Mountain must remain intact for 1,000 years to satisfy Nuclear Regulatory Commission...
Dynamic Use of Geoscience Information to Develop Scientific Understanding for a Nuclear Waste Repository
The development and safety evaluation of a nuclear waste geologic repository require a proper scientific understanding of the site response. Such scientific understanding depends on information...
Infill Sampling Design for Geologic Site Characterization of Potential High-Level Radioactive Waste Repositories
Geologic site characterization is fundamental to the selection and design of a high-level radioactive waste repository. Yet, to date, the simple question 'how many samples...
