Rehabilitation of TVA's Great Falls Project
After seventy-one years of productive service, this two-unit, 31,860 kV plant is undergoing a major rehabilitation. The deterioration of the project has been of concern since the beginning...

Echo Dam Small Hydrodevelopment
In the mid 1970's, Bountiful City Light and Power began investigating alternative energy sources to furnish power to their distribution system. They engaged the firm of Bingham...

Building Bridges Faster
Guidelines are presented that tell how to write a contract that will lead to radical reductions in the time to build or rebuild a bridge. The article covers how to write an incentive/disincentive...

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...

Mining Subsidence Effects on Transportation Facilities
This paper presents case history information about mining subsidence effects on transportation facilities, including bridges, pavements, and culverts. Most of the field observations pertain...

A Review of Some Aspects of Grouting for Mine Subsidence Control
This paper presents an overview of the state-of-the-art of grouting as a technique for mine subsidence control. A review of some aspects of grouting theory is presented, and illustrative...

Subsidence Over AML and Its Causes?A Case Study
Subsidence over abandoned mined lands can be attributed to several causes. For purposes of compensation and liability and developing remedial measures, it is essential to identify the...

Response of Structural Systems with Uncertain Parameters: A Comparative Study of Probabilistic and Fuzzy Sets Models
Due to the limitation in space, this paper only presents the conclusions of a study on the response of structures with uncertain properties such as mass, stiffness and damping. In the...

Comparison Between Linearization and Gaussian Closure
A variety of approximate solution techniques have been developed for analysis of nonlinear systems. The most widely used method has been equivalent linearization. Recently a general closure...

Reduction of Imposed Loads for Beam and Column Design
Imposed loads on beams and columns are generally reduced to effect in economy in design. A study to evaluate the reduction criteria by evaluating the Equivalent Uniformly Distributed Loads...

Reliability Analysis of Single-Headed Anchor Bolts
Several design equations for predicting the capacity of single-headed anchor bolts embedded in plain concrete have been recommended in the United States. The capacities predicted by these...

A Probabilistic Comparative Study of Various Base Isolation Systems?Nonstationary Earthquake Excitation
A probabilistic comparative study of various base isolation systems is carried out. The laminated rubber bearing with and without lead plug, the resilient-friction, and the EDF base isolation...

Virginia Case Studies of Risk Based Drainage Design
The goal of this paper is to apply a practical engineering risk-based method of design of pavement and surface drainage systems to three Virginia case studies. The target systems include...

Least-Cost Scheduling of Advance Maintenance Dredging
New methods are suggested for scheduling advance maintenance dredging operations on isolated reaches of navigation channels. For reaches where siltation occurs regularly as a result of...

Issues in Regional Water Resources Planning and Management: A Great Lakes Case Study
This paper focuses on the obstacles and opportunities inherent in regional resource management efforts, with the Great Lakes Basin serving as a case study. The following areas are addressed:...

Retrospective Look Into Design Challenges of Boston Interceptors
The purpose of this paper is to share with designers and owners a retrospective evaluation of a major sewer system design effort. The process by which a major sewer design project reaches...

Water Main Condition Monitoring A Case Study
Water main breaks, routine occurrences for water utilities, reflect the structural failure of the main. The trend in break patterns is increasing for many utilities in the U. S. Several...

Roads for Sale
Due to the decline in available federal revenue for transportation facilities, privatization is becoming a common alternative to project financing. A case study of a public/private partnership...

Energy/Environment Opportunities for Civil Engineers
In the West, Nuclear Facilities Decommissioning; In the East, Implementation of Waste to Energy Systems
The papers in this book examine and provide illustrations for civil engineering opportunities in resolving apparent conflicts between needs for energy generation and environmental acceptability....
