The Application of Vertical Seismic Profiling and Cross-Hole Tomographic Imaging for Fracture Characterization at Yucca Mountain
In order to obtain the necessary characterization for the storage of nuclear waste, much higher resolution of the features likely to affect the transport of radionuclides will be required...
The Source Term for HLW Disposal in the European Communities' R&D Programme
During the last five years, the EC's research programme on radioactive waste has focused much of its investigation in the field of HLW management on the source term for geologic...
Analysis of Uncertainty in Ground-Water Quality Monitoring Network Design
The paper reviews alternative approaches to ground-water quality monitoring network design. Four general approaches to network design are reviewed: (1) hydrogeologic, (2) simulation, (3)...
Model Tests for Design of Vibration-Free Gates
Experimental results are presented of hydraulic forces acting on an underflow gate. Underflow gate is a socalled bluff body and a review of the mechanism of vibration caused by separation...
Geocomposites Simplify Methane Barrier/Venting System Design
A case history describing the use of a geomembrane and geocomposite to simplify the design of a combined subsurface barrier and venting system is presented. The passive barrier and venting...
Gateways to Understanding
Automating engineering design processes are crucial to the growth and the very survival of professional services providers. The need to enhance their competitiveness and the value provided...
An Education in Tunneling
A senior civil engineer and winner of the 1988 Martin Kapp Foundation Engineering Award describes the evolution of U.S. tunneling technology and practice. Trained as a structural engineer,...
An Education in Tunneling
In this follow-up to the author's article in the April 1989 issue of Civil Engineering, this senior civil engineer and winner of the 1988 Martin Kapp Foundation Engineering...
Foundation Engineering Constraints in Karst Terrane
Cavity-prone carbonate rocks are found in many Appalachian valleys and represent a poorly recognized hazard. This paper reviews the nature of the problem of founding above these Cambro-Ordovician...
Influence of Geologic Development on Horizontal Stress in Soil
Geologic history commonly controls the stress in natural soils, so that an understanding of the geology allows an assessment of the horizontal stress. This paper describes mechanistically...
Geotechnical Judgment in Foundation Design
This paper summarizes the initial findings of a research project to investigate the judgment-making process of foundation engineers. Solutions for a typical design problem were solicited...
Structural Foundation Practices for Highway Projects
The state-of-practice by State transportation agencies, in the area of structural foundations, is compared between the late 1970's and the present. The structural foundation...
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...
Chemically Induced Foundation Heave
The Kerr-McGee Electrolysis Plant in Henderson, Nevada has had recorded upward movements of portions of the building in excess of 18 inches. Contours of the measured heave indicate that...
Cokriging for Evaluating Agricultural Pollution
Subsurface drainage data from irrigated lands near Twin Falls, Idaho were used. Total Dissolved Solids and NO3-N were selected as variables. The...
The Influence of Water Tables on Herbicide Losses
Atrazine and metolachlor were applied preemergent on April 22, 1987, to silage corn on high watertable fields which were either subsurface drained (104 mm drain tubes 1 m deep) or surface...
Safer Dams
During the last 11 years, thousands earth dams have been inspected. Here are four that were rehabilitated. Army Corps inspections are phase I of the program, and have been completed. The...
Evaluating Sinkhole Hazards in Mantled Karst Terrane
Sinkholes are the most serious geologic hazard in karst terrane because they can damage structures, drain ponds and lakes, and allow direct infiltration of groundwater contamination. The...
Exploration of Karst Conditions in Central Florida
Walt Disney World, which comprises some 28,000 acres (11,000 ha) in central Florida, is underlain by cavernous limestone and is characterized by karst topography; with distinct low ground...
Exploring Karst Terrain with Air Track Drilling
Pneumatic-powered track-mounted, percussion drills can be used to perform or augment geotechnical investigations in some karst settings. The air track drill is best suited to exploring...
