Summer Falls High Head Kaplan Turbine Project
The Summer Falls Project is located on the Main Canal of the Grand Coulee Irrigation Project approximately eight miles south of Coulee City in Grant County, Washington. The power development...
Subsurface Savings
Less conservatism than usual in designing building foundations is being accepted or demanded by some owners to save money. The article describes four examples of cost-cutting innovations,...
Roller Compacted Concrete Dams?An Overview
The development of roller compacted concrete for gravity dams is traced from forerunners, through its use at the Shihmen and Tarbela Dam Projects to Willow Creek Dam and the Japanese Roller...
Planning, Design and Cost Estimates for RCC Dams
Engineers, planners, and officials of agencies responsible for developing water resource projects are confronted with preparing preliminary designs and cost estimates for dams. This paper...
Cedar Falls Roller Compacted Concrete Dam
This paper presents the design, material testing, quality control, and construction considerations applicable to a small Roller Compacted Concrete (RCC) dam. The Cedar Falls RCC dam is...
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...
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...
A Stochastic Model for Low-Cycle Elastic-Plastic Fatigue Crack Growth
In this paper a stochastic process approach is considered to represent the random nature of the low-cycle (elastic-plastic) fatigue crack growth process. A semi-Markov renewal model is...
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...
Bridge Reliability Evaluation Using 3-D Analysis and Damage Scenarios
This paper reports analytical investigations into the system strength and reliability evaluation of existing bridges using 3-D inelastic analysis and damage scenarios. In this context,...
Variability Analysis of Bridge Responses Using the Semi-Continuum Method
The semi-continuum method is used for Monte Carlo simulation of a large number of bridges. It is confirmed that the mean values of responses can be obtained deterministically, and their...
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...
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,...
