Structural Analysis for the Student
The transition from student to practicing structural engineer can be a very 'eye-opening' experience. From the classical right-wrong classroom solutions of well-defined indeterminate structures,...
Structural Analysis in Context
The issues of what student should learn about structural analysis and how it should be taught are explored considering the purposes of structural analysis in engineering practice and the...
Inspections, Evaluations and Modifications for Corps of Engineers Dams
The Corps of Engineers owns and operates 580 dams in the United States. As these dams become older (199 are over 50 years old), dam safety and modifications play an increasing role in...
Embankment Dam Safety
Procedures for identification and evaluation of conditions which can lead to catastrophic dam failure through either piping or deep seated instability of the downstream surface are presented....
Three-Dimensional Stability Analysis of Carpenter Dam
This paper describes the three-dimensional stability analysis of Carpenter Dam. The presence of keyed construction joints between dam monoliths at Carpenter Dam can significantly affect...
Risk Assessment: A Tool for Dam Rehabilitation Decisions
A phased approach to the dam rehabilitation decision problem is presented. The approach is based on viewing the newer dam safety evaluation approaches of incremental damage assessment...
Prediction of Embankment Dam Breaching for Hazard Assessment
Downstream hazard assessments for dams require prediction of 1) whether a breach could form, and 2) the hydraulic characteristics of the breach for use in calculations of discharge and...
Risk-Based Methodology for Seismic Rehabilitation of Earth Dams
A methodology for seismic risk analysis of earth dams is described. The procedure utilizes seismological and geotechnical inputs together with the associated uncertainties and provides...
Reliability Analysis of Navigation Structures
Methods for probabilistic stability analyses of concrete monoliths at hydraulic structures were developed and tested. Numerous analyses were performed using data from six actual structures...
Saylorville Spillway: Emergency to Service Spillway
The spillway for Saylorville Lake located on the Des Moines River, 12 miles north of the city of Des Moines, Iowa, a large metropolitan, was designed as an emergency spillway. Due to subsequent...
Some Considerations for Remedial Grouting for Seepage Control
The inadequate performance of grout curtains and the consequent need for remedial and supplementary grouting of dam foundations probably arises, in essentially all cases, from a combination...
Development and Evaluation of Remediation Strategies by Deformation Analysis
Deformation analysis is providing guidance for the most efficient and economical seismic remedial treatments for Mormon Island Auxiliary and Sardis dams. The computer program TARA-3FL...
Seismic Stabilization of St. Joe State Park Tailings Dams
Tailings dams constructed by the `upstream' method are known to be seismically vulnerable, but field experience indicates that their seismic stability usually improves following termination...
Seismic Rehabilitation of Echo Lake Dam
Echo Lake Dam is an existing dam raising a natural lake in the Sierra Nevada in California, along the western edge of the Tahoe Basin. The dam was an embankment built with steep, hand...
Liquefaction Evaluation by Seismic Potential Procedure
Empirical procedures in common use for liquefaction evaluation employ information from a variety of sources in order to evaluate whether or not a site will undergo liquefaction. The information...
Reduction of Liquefaction Potential by Compaction Grouting at Pinopolis West Dam, SC
A previous 1984 field study and subsequently published paper (Salley et.al., 1987) described the seismic design background and evaluated the potential success of compaction grouting to...
Prestwood Lake Dam Rehabilitation
The Prestwood Lake Dam located in Hartsville, South Carolina is owned by Sonoco Products Co. It originally was a wood structure built in 1895. That structure was washed out by a hurricane...
Improving Dam Safety Using a Fin Drain
Bloemhoek Dam is an embankment dam with a maximum height of 21 m, which leaked severely after first filling in 1978. This leakage resulted in the development of `boils' over a portion...
Graham Lake Dam Remedial Measures Project
Graham Lake Dam consists of a 550-foot long earth embankment and an 80-foot long concrete spillway. Several concerns were identified during project inspections including limited spillway...
Certified Safety Assessment of Zoccolo Dam
The paper reports one of the activities carried out in the framework of a so called `certified assessment of safety' program activated by ENEL SpA - Italian National Electric Board - in...
