RCC in Dams in Australia
The design, construction and performance of the first three dams constructed in Australia, using RCC are described. Aspects covered in the paper include designing for zero cohesion between...
Saco Dam?South America's First RCC Dam
Because of cost and a lack of suitable embankment materials, Saco Dam at Nova Olinda in Paraiba, Brazil, was redesigned and built with lean roller compacted concrete (RCC). The structure...
Roller Compacted Concrete Design for Urugua-I Dam
Gravity dam construction by the roller compacted concrete method (RCC) has received widespread interest following completion of Shimajigawa Dam in Japan (1981) and Willow Creek Dam in...
Roller Compacted Concrete with Marginal Aggregates
Roller compacted concrete is a technology which is vastly expanding beyond the traditional uses of pavement and dam oriented projects. Hornsby Bend Wastewater Treatment Plant required...
Karstic Foundation Problems Sunny Point Railroad
Active limestone sinkholes have been causing problems and affecting the operation of the access railroad to the Military Ocean Terminal, Sunny Point, North Carolina (MOTSU) since 1962....
The MPSP System: A New Method of Grouting Difficult Rock Formations
In unstable rock masses the traditional stage grouting methods may prove impractical or ineffective. A recent innovation has been the Multiple Packer Sleeved Pipe (MPSP) System. Akin to...
Foundation Treatment of Karstic Features Under TVA Dams
TVA has constructed many of its dams on limestone foundations. Some of these foundations have been highly weathered and required special treatment not only to ensure strength but to develop...
Shallow Foundation on Sand Underlain by Soft Clay with Geotextile Interface
One technique for improving the load-bearing capacity of shallow foundations on soft clay soil is to construct them over a compact granular fill laid over the clay layer. However, the...
Design of Ash Basin Dike across Cove
Embankments built over soft, unstable foundation materials had required that the materials either be removed or reinforced. With the introduction of geotextiles, it is now economically...
Mechanisms of Subsidence Induced Damage and Techniques for Analysis
Structural damage due to mining induced subsidence is a function of the nature of the structure and its position on the subsidence profile. A point on the profile may be in the tensile...
Application of Bayesian Methods to a Geotechnical Site Investigation in Mississippi
In 1981, the Army Corps of Engineers constructed an ammunition storage area at Bay St. Louis, Mississippi. This storage area is part of the Mississippi Army Ammunition Plant (MSAAP). Prior...
Reliability of Geotechnical Systems Considering Geological Anomaly
Anomaly statistics at a given site are first assessed through Bayesian methodology on the basis of site exploration data. Several methods may be then used to incorporate the anomaly uncertainties...
Extent of Water Quality Effects of Dams?A National Viewpoint
An overview of phosphorus impacts on impoundments, a subset of the contents of the Dam Water Quality Report is presented. The U.S. Environmental Protection Agency (EPA) is the lead investigator...
Water Conservation and Floodplain Regulation at Barrett Dam?San Diego, CA
Barrett Dam is owned and operated by the City of San Diego, California. This paper describes the response of the dam to heavy storms that occurred in Southern California in 1980. Computer-generated...
Swiss Cheese Box Girders
Now going up in the French Alps, the Sylans and Glacieres viaducts have decks supported by three-dimensional arrays of concrete trusses. The superstructures look like concrete box girders...
Steel Pipe Foundations for Deep Water
Four innovations are helping to make steel pipe piles more popular for foundations in deep water in Southeast Asia. Until recently steel was usually rejected for these applications, because...
Injecting an Oxygen Fix
Seasonal dissolved oxygen deficiencies are an old problem in hydropower discharges from deep impoundments. At the Richard B. Russell Dam near Savannah, Georgia, an innovative solution...
Monitoring of a Gas Main During Construction
This paper focuses on the task of formulating and implementing a viable plan for protecting an existing gas main located in a construction site where construction activities include excavation,...
Dams and Earthquakes: A Shaky Relationship
The rarity of earthquake-related dam failure does not mean that it can't happen. A phased geologic assessment could prevent potential catastrophe by determining where and...
The Cause of the Johnstown Flood
The Johnstown flood occurred in 1889, when an earth and rock dam failed during a record rainfall in eastern Pennsylvania. The flood was one of the worst civil disasters in the U.S.; 2,200...
