Terminal 5 Renovation—Port of Seattle
The Port of Seattle is currently renovating its Terminal 5 facility on the west bank of the Duwamish River on the west side of Harbor Island in Seattle. This paper describes the methods...

Puget Sound Alluvium: A Challenge in Design of Pile Supported Port Facilities with Dredged Slopes
The geotechnical investigation, evaluations, and recommendations for the Port of Seattle Terminal 18/20 Improvement Project are described and compared with observed performance during...

Borehole Shear Test and Slope Stability
Three Iowa landslides analyzed on the basis of Borehole Shear Test (BST) data are reported. The soils included CL and ML loess and glacial till, and CH clay shale. Back-calculations from...

Landslide Investigation Utilizing Electric Cone Penetration Testing
A geotechnical investigation was conducted of landsliding at a hillside residential property to evaluate both the extent of the landslide and the stability of the fill materials as well...

Flood Risk Below Steep Mountain Slopes
Alluvial fans spread at approximately the critical hydraulic slope below apexes at canyon mouths. Periodic torrents that rage out of the canyons are devastating at the apex and have diminishing...

Relative Landslide Susceptibility in Davis County, Utah—A Multivariate Approach
The complex distribution of soil properties makes prediction of slope stability extremely difficult in these mountain watersheds. The need to assess these watersheds for their susceptibility...

Gully Incision Prediction on Reclaimed Slopes
An investigation was conducted to estimate the potential of gully intrusion into reclaimed waste impoundments. A series of eight reclaimed impoundments exhibiting gully intrusions were...

Behavior of Sediment-Laden Plumes on Steep Slopes
The near field behavior of dense, sediment-laden flows on steep slopes was investigated as part of a study of mine tailings disposal. A literature review indicated that field and laboratory...

Analysis of Alluvial Fan Flooding
Alluvial fans are estimated to cover approximately one third of the land area in the southwestern United States. Because of their relatively gentle slopes and well draining characteristics,...

A Microcomputer Program for Bearing Capacity Analysis
The objective of this paper is to introduce an IBM/PC/XT/AT microcomputer program for the Bearing Capacity Analysis of Shallow Foundations. The program incorporates the bearing capacity...

Lessons Learned From Examination of Membrane Roofs in Alaska
During 1984 and 1985 airborne infrared roof moisture surveys were conducted of membrane roofs at Army installations in Alaska. Many of these roofs were also visually inspected and cored...

Geotechnical Aspects of Strontia Springs Arch Dam
The bedrock at the Strontia Springs damsite consists of generally excellent quality granitic and metamorphic rock, except for a wide shear zone located beneath the dam in the lower valley...

A Contractor Looks at Slope Protection for Arctic Offshore Artificial Islands
Some thirty artificial gravel islands for oil and gas drilling/production have been built in the Beaufort Sea since early 70's. Protection of slopes of the islands and causeways...

Influence of Artificial Island Side-Slopes on Ice Ride-Up and Pile-Up
An artificial island slope protection scheme must be able to inhibit ice ride-up and pile-up in order to minimize operational interruptions. The prediction of ice ride-up and pile-up mechanisms...

Ice Forces Due to Impact Loading on a Sloping Structure
Two approximate methods are presented for determining Dynamic Magnification Factors due to floe impact on sloping structures. Some of the physical processes involved are treated simplistically,...

Ice Loads on Structures With Compound Slopes
Many of the offshore drilling structures proposed for use in the Arctic have sides with multiple slopes. Sloping walls are used at the waterline to cause the ice sheet to fail in bending...

Borrow Resource Studies in Near-Shore Areas of Alaska's North Slope
Innovative and cost-effective techniques are utilized in the exploration and analysis of near-shore sources of sand and gravel on Alaska's North Slope. High quality sources...

The Sand Mattress Method of Slope Protection
The sand mattress concept offers promise as an economical alternative to sand bag armor for two distinct applications: (1) slope protection for exploratory islands and/or causeway facilities,...

Asphalt Revetments for Slope Protection in the Arctic
Experience in the Netherlands demonstrates that slope protection of coastal embankments subjected to heavy wave action can be accomplished with lining systems made of mixtures of asphalt...

Snow Effects on Pile Design Temperatures
The construction of North Slope aboveground pipelines and gathering lines is generally from snow workpads constructed proximate to existing access roadways. The pile support centerline...
