Do Simplistic Methods of Foundation Design Produce Reliable Foundations?
Many foundations today are designed using deterministic (single value) analysis techniques which do not reflect the natural variability of soil properties. If the standard deviation and...
Use of Computers for Soil and Rock Testing
The Bureau of Reclamation's central geotechnical laboratory in Denver, Colorado, routinely uses computers and associated electronic measurement devices for data acquisition,...
Reliability in Rock Engineering
This paper reviews approaches to reliability in rock engineering through a survey of methods developed at MIT. Since these methods are intended to be applied in engineering decisions,...
Methodology for Optimizing Rock Slope Preventative Maintenance Programs
Rock slopes along transportation routes can fail in several different modes, with various types and magnitudes of consequences. The 'risks' associated with such...
Use of a Tie-Back Retaining Wall to Stabilize a Moving Landslide
After failure of a gravity retaining wall, a moving landslide was stopped and stabilized by a tie-back retaining wall. The design considered the active landslide and residual strength...
Data Base of Seismic Body Wave Velocities and Geotechnical Properties
A data base of seismic velocities measured in soils and standard geotechnical engineering material properties has been established at the U.S. Army Engineer Waterways Experiment Station...
Results from Selected Oil-Spill Response Research
Recent large oil spills from tankers have reaffirmed the need for continuing technology assessment and research to improve oil-spill response capabilities. The Minerals Management Service...
Moving Muds in the Marine Environment
Fine sediments with cohesive properties abound in the marine environment. We review idealized relationships that are useful in understanding flow behavior of important components of marine...
Functioning of Multi-Row Sand Fences in Forming Foredunes
Foredunes on sandy beaches are best developed through use of a series of fences by which dune height and width can be controlled. In a previous paper, the authors examined the functioning...
The Sedimentary Organisation and Behaviour of Drift-Aligned Gravel Barriers
Drift-aligned barriers formed of coarse clastic materials and described in terms of their organisational evolution at two levels, a) sorting and selection of clasts; b) development of...
Numerical Modelling of Lower Lias Rock Failures in the Coastal Cliffs of South Wales
A model has been developed to evaluate slope failure in the interbedded limestone and mudstone Lower Lias series which outcrop for some 30 km in coastal South Wales. Computer simulation...
Chemical Composition, Physical Properties and Off-Site Migration of Municipal Landfill Gas
A sampling program of headspace gas from four monitoring wells and of off-site migration at three property line sites was conducted as part of a remedial design of a municipal landfill....
Behavior of Three Organic Chemicals Passing Through Columns Packed with Sand and Silt in the Presence of Landfill Leachate
This study examines the effect of leachate on the migration of three common industrial chemicals in unsaturated flow under two sets of soil conditions: sand and sand with a layer of silt....
Influence of Moisture Influx on the Hygro-thermal Performance of a Clay Buffer Developed for Nuclear Disposal Vault
This paper focusses on an experimental study that investigates the heat transfer and moisture movement within a bentonite clay buffer compacted in a borehole located in a granite block....
A New Graphic Technique for Reporting Soil Quality Analyses
Boston's Artery/Harbor Tunnel Project is currently the United States' largest highway construction project. One of its major issues is the disposal of an estimated...
Design Considerations for Radial Key Retrofit
A practise that is becoming more and more common is to retrofit hydro-electric generators with Radial Key Systems. There are significant design considerations that must be made to ensure...
B.C. Hydro's Practice for Assessing the Foundations of Existing Dams on Rock
Since the early 1980's B.C. Hydro has carried out dam safety reviews which included 33 gravity and embankment dams founded on rock. The foundations include moderately jointed,...
Foundation Investigations of Concrete Dams
This paper discusses a series of foundation investigations conducted on concrete dams by Pacific Gas and Electric Company. The paper focuses on investigative techniques, equipment, appropriate...
Geotechnical Aspects of the Underground Excavations at the Kemano Completion Project
The Kemano Completion Project is the addition of four generators of 540 MW installed capacity to an existing eight-unit underground hydroelectric generating station owned and operated...
Innovative Design for Diversion
A conventional diversion scheme to facilitate construction of the 120 m high rockfill dam for the Beni Haroun project in Algeria would have required three 10 m diameter diversion tunnels....
