The Assessment of Freeze-Thaw Damage in Cement Stabilised Soils
Whilst the ASTM Freeze-thaw test was not originally conceived as a means for classifying the frost resistance of cement stabilised soils it has become accepted for this purpose, with the...
Structural Monitoring Concepts for Arctic Pipelines
Terrain instabilities producing differential soil movements are the predominant features affecting the structural integrity and design of buried pipeline systems in the arctic. Current...
Nonlinear Analytical Models for Interfacial Plug Stresses in Creeping Salt Formation
Analytical and numerical simulation models are presented which predict the nonlinear time dependent behavior of an expanding plug in a creeping environment heavily dependent on the storage...
Design of Impact Limiters for Waste Fuel Shipping Casks
Impact limiters are often used to control the decelerations experienced by a waste fuel shipping cask when it is subjected to the hypothetical accident condition loadings. Simplified design...
Geotechnical Data Acquisition and Computerized Analysis
In 1983 and 1984, an exploratory tunnel was constructed as part of the geotechnical exploration program for two highway tunnels to be constructed for the improvement of Interstate 70 through...
Continuous Loading Consolidation Testing Using a Microcomputer for Control and Data Acquisition
An overview of some of the methods of one-dimensional consolidation testing currently in use is presented, including the load-increment test, the constant rate of strain test, the constant...
A Demonstration Expert System to Aid in Assessing Groundwater Contaminating Potential by Organic Chemicals
An expert systems approach to evaluating mobility and degradation of organics in soil systems is compared to conventional programming techniques. An expert system has been developed in...
A Method for Computerized Site Characterization
Site characterization, the process of evaluating subsurface soil, rock, and groundwater conditions and their impact on project design and construction is a common element in every major...
Effectiveness of Erosion Control
Erosion control in the urban environment is addressed from the perspective of the mechanisms of erosion. The primary cause of erosion in urban areas is flowing water. Measures are identified...
Constructing a Better Environment
The civil engineer is traditionally designated the jobsite environmental engineer during construction, and is responsible for managing environmental protection and monitoring. Jobsite...
Grouting a Sand Dam
Hardy Dam, owned by Michigan's Consumers Power Co., was constructed in 1929 by dumping sand from railroad trestles for an embankment to support a concrete core wall. Some...
Soil Nailing a Wall
Soil nailing is the reinforced-earth idea (in which the earth must be backfilled behind the wall) applied to cut situations. Soil nails are an inexpensive post-tensioned tieback, consisting...
Jet Grouting: Snail's Pace of Adoption
Jet grouting is grouting of soil, but the process, the equipment and the subsurface product are different from the familiar ones. Here the cement grouting is mixed in situ with the surrounding...
Wicking Bay Muds
Mud deposits in the San Francisco Bay area make construction difficult. Subsidence prevents many from building in the area. Engineers for O'Brien Kreitzberg conquered this...
Research on Transportation Facilities in Cold Regions
Transportation facilities research in cold regions, reported in this session proceedings, begins with a field study showing that ground surface characteristics have a significant effect...
Ground Freezing for Construction
For almost a century, freezing has been used successfully as an art to stabilize ground and control groundwater. First employed by the mining industry in Europe, it has since been widely...
Trouble in Our Own Back Yard
One million tanks will leak toxic and hazardous substances into the U.S. soil within the next four years. Prevention begins with rapid discovery and probability analysis. Various cleanup...
Concrete Quality Control and Quality Assurance on Strontia Springs Dam
An essential part of the construction management services provided on Strontia Springs Dam was the quality control of material, mixture proportions, and production for all concrete placed...
Geotechnical Features of Fur Seal Island Design
In summer 1983, Texaco made plans to construct an artificial island in Harrison Bay of the Beaufort Sea to serve as a platform for exploratory drilling. Fur Seal Island is to be located...
Porewater Pressure in Clays Below Caisson Islands
Unfrozen lightly overconsolidated clays are a significant factor in the design and performance of exploration caisson retained islands in the Canadian Beaufort Sea. At two sites (Tarsiut...
