Recent Developments in Isolation Hardware
Most isolation systems have at least two physical components: one specifically intended to add flexibility and the other to control the resulting deflections. However, other elements may...
Emergency Response to the 1983 Debris Flows Along Utah's Wasatch Front
The wet cycle experienced in Utah culminated in approximately one thousand landslide triggered debris flows caused by rapid melt of unprecedented snow accumulation in the Wasatch Mountains,...
Putting a Lid on Liability
In the face of the recent landslide of claims and litigation, limiting your firm's liability sounds impossible. But there are ways to protect yourself, from selling quality,...
The Eccentric Entrance
Architects design irregularly shaped buildings to give their clients something different, and this creates problems for structural engineers, especially in earthquake zones. The Brinderson...
Verification of a Generalized Mudflow Model
This paper presents the results from recently completed studies verifying the accuracy and applicability of a generalized one-dimensional model for dynamic routing of mudflows. Numerical...
Ester West Slide?A Case History
An 80 foot high embankment was benched into graphitic schist permafrost on a north facing slope approximately 25 miles west of Fairbanks, Alaska. Soon after construction approximately...
Coal Mining in Alaska's Interior: Problems and Solutions
The Usibelli Coal Mine located in Healy, Alaska is currently the largest operating coal mine in the state of Alaska. The mine has recently increased production to nearly 1. 7 million tons...
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....
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...
The Earthquake Barrier
The earthquake barrier protects buildings from the horizontal ground vibrations of an earthquake by installing a 'force barrier and an energy barrier' at the...
Landslide Dams
Processes, Risk, and Mitigation
Landslide dams have proved to be both interesting natural phenomena and significant hazards in many areas of the world. A few of these blockages attain heights and volumes that rival or...
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 Investigations Using the Weight Penetrometer
The weight penetrometer is a light weight device and can be easily deployed on slopes not accessible to conventional exploratory tools such as drill rigs or cone penetrometers. The weight...
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...
The Mudslide Profile Method to Measure the Undrained Shear Strength of Muds
Mudslides have been reported to have a very distinctive profile. Using this distinctive profile, a method is presented to analyze the stability of the mudslide at limit equilibrium conditions....
