Piles Under Dynamic Loads
This proceedings,
RCC at 10
Tens years after the first roller-compacted concrete (RCC) dam in the U.S.�the 169 ft high Willow Creek Dam in Oregon�was completed, the method has gained wide acceptance around the world...
Seismic Assessment of Tailings Dams
A significant portion of the operating and closed large dams in North America are tailings dams used to impound wastes from mining operations. Often these dams were built by mine personnel...
Rebuilding an Illusion
A dam that controls the level of Fall Lake, a major entry to the Boundary Waters Canoe Area Wilderness of northern Minnesota had to be rebuilt, but federal agents barred constructors from...
Under the Undersea World
Soil conditions in New Orleans are generally unfavorable to the construction of large structures, and exceptionally so along the Mississippi River banks, which tend to slide. But that...
Sending Steel Down the River
Completed last October 1990, the Roosevelt Lake Bridge is now the longest two-lane, single span, steel-arch bridge in North America, spanning 1,080 ft. Also, the longest steel arch bridge...
Experimental Study of Adfreeze Heaving of Augered Caisson Footings
In order to establish the required depth of augered caisson-type footings in cold regions and their optimal design against adfreeze heaving, an experimental field investigation has been...
Processed-Snow Foundation Design at the Summit of the Greenland Ice Cap
The design and construction of a processed-snow foundation berm for an elevated building located at the summit of the Greenland Ice Cap is described. Weather conditions and design provisions...
A Mechanistic Approach to Pavement Design for Nome Airport
The analysis of performance and design of the pavement structure for the North-South runway at Nome Airport is based on the mechanistic approach. In the mechanistic approach, calculated...
Treatment of Unstable Foundation Areas in Alaska's Pavement Management System
In the State of Alaska Department of Transportation and Public Facilities Pavement Management System (PMS) unstable foundation areas are defined as sections of roadway that experience...
Minnesota Road Research Project - An Overview
The Minnesota Department of Transportation in cooperation with the Federal Highway Administration and the Local Roads Research Board of Minnesota is constructing the Minnesota Road Research...
Modeling of Floating Ice Sheets
Rectangular finite elements are studied and their suitability to investigate behavior of floating ice sheets is discussed. A simple model of the plate on one parameter, Wrinkler type,...
Hydro Rehabilitation?Innovative Solutions
Most hydro facilities have been in operation for many years and, consequently, must periodically have been rehabilitated. The high cost of energy, labor, materials, and financing dictate...
The Human Factor in Failures
Human shortcomings cause three-quarters of project failures. A study of 500 case histories led to this assumption. One such failure at the Walter Bouldin dam in Alabama, is described in...
Fixing Foundations
Conventional underpinning or pilings are still the most common construction methods used to strengthen foundations, but new grouting techniques are giving engineers some fresh alternatives....
Downstream Danger from Sudden Discharges of Water
The sudden, unexpected release of water by hydropower facilities poses a threat to fishermen and boaters immediately downstream. The characteristics of the danger can be identified, however,...
Dams for the 21st Century
Water shortages around the world are mounting. Construction of dams, development of groundwater and improvement of irrigation practices are necessary to increase water supplies. Vast quantities...
Reliability of Beams on Uncertain Foundation
A two phase approach is developed to evaluate the reliability of a finite linear elastic beam subject to a random point load on uncertain elastic foundation. In phase 1, an approximate...
Characteristics of Flow Over the Bucket with Gradually Varied Curvature
The bucket of a high spillway dam or a spillway tunnel is one of the parts that easily to be damaged by cavitation. A new type of bucket curve was suggested with gradually varied curvature...
Time-Domain Transmitting Boundary Condition in Fluid-Structure Interaction Studies
One of the major difficulties in the nonlinear analyses of fluid-structure interactions has been the lack of exact expressions for the transmitting boundary in the time domain. Researchers...
