Long Term Performance of the Goldstream Creek Bridge
In 1964 the Alaska Department of Transportation and the U. S. Army Cold Regions Research and Engineering Laboratory initiated a cooperative study which in the long-term generated a significant...

Geotechnical investigation: Cominco's Red Dog Mine Facilities
The siting of major facilities associated with development of the Red Dog Mine Complex in Northwestern Alaska on relatively warm permafrost soil and rock presented geotechnical engineers...

Waterfront Stabilization Project, Kaktovik, Alaska
This paper discusses an innovative 384-foot treated-timber cribwall design utilized to control rapidly accelerating thermal erosion and establish a roadway along the bluff on the Beaufort...

Bearing Capacity Calculations for Piles in Permafrost
Small-scale model piles frozen in various soils were tested at constant rates of displacement and constant load. The derived values were used to calculate the maximum allowable stress...

Spring Stiffness for Beam-Column Analysis of Soil-Structure Interaction Problems
The objective is to provide a simple means of analytically combining a two-dimensional foundation with a beam-column structure so that the procedure can be used for preliminary design...

Dynamics of Machine Foundation
The art of designing machine foundations, supporting vibratory load has changed from the approximate rule-of-thumb to the scientifically sound engineering procedure. However, the vast...

Tunnel Closure Prediction by Finite Element Method
Discussed is the tunnel closure prediction of a drainage tunnel using finite element methods. Separately, three finite element programs were used to predict the closure. The results of...

Interactive Design of Reinforced Concrete Foundations
A new, highly graphical foundation design program, FOUNDATION-3D, provides the designer with a variety of easy to use foundation design tools in a flexible interactive environment. It...

Glen Canyon Dam's Quick Fix
When the spiullways at Glen Canyon Dam were severely damaged from unexpected flooding in 1983, the Bureau of Reclamation had just 10 months to repair the tunnel spillway lining and build...

Rowes Wharf: A Case Study in Substructure Innovation
Rowes Wharf is a project with many unique features. This paper has attempted to briefly review just one of these features - Up/Down construction. The willingness of the development team...

Large Mat Foundation Analysis on Expansive Soil
This paper describes a comparison of predicted and observed performance of mat foundations on stiff expansive soil. Foundation performance was predicted using a new computer program BOSEF...

A Perspective on Landslide Dams
The most common types of mass movements that form landslide dams are rock and soil slumps and slides; mud, debris, and earth flows: and rock and debris avalanches. The most common initiation...

Landslide Dammed Lakes at Mount St. Helens, Washington
The collapse of the north face of Mount St. Helens on May 18, 1980, and the debris avalanche that resulted blocked outflow from Spirit Lake and Coldwater and South Fork Castle Creeks....

Design and Construction of the Spirit Lake Outlet Tunnel, Mount St. Helens, Washington
In 1982, a governmental task force was formed to evaluate the hazard posed by the blockage of Spirit Lake that resulted from the eruption of Mount St. Helens in May 1980. An analysis was...

The 1983 Landslide Dam at Thistle, Utah
The Thistle, Utah, landslide began rapid movement on April 13, 1983. The landslide, a reactivation of an estimated 22 multiplied by 10**6 m**3 of old landslide debris, blocked Spanish...

Control of Thistle Lake, Utah
In April of 1983, the Thistle slide blocked the flow of the Spanish Fork River and traffic using the Denver and Rio Grande Western Railroad, U. S. Highway 89, and U. S. Highway 50 and...

Landslide Damming in the Cordillera of Western Canada
Major landslide dams in the Cordillera are a result of rock slope movements, landslides in stratified Pleistocene deposits, and landslides in till or colluvium in steep mountain watersheds....

Landslide Dams in Japan
Damming of rivers by landslides is common in Japan because widespread unstable slopes and narrow valleys exist in conjunction with frequent hydrologic, volcanic, and seismic landslide...

Landslide Dams in South-Central China
The Yangtze and Yellow Rivers and their tributaries drain mountainous areas of south-central China that are highly susceptible to landslide activity. This paper describes six major cases...

Base Isolation in the Design and Construction of Power Plant Structures
This technical paper summarizes the results of some of the recent studies performed to assure technical feasibility in isolating safety-related nuclear power plant structures. The particular...
