Geosynthetics in Dam Rehabilitation
In the first part of this paper, a review of the various types of geosynthetics is presented and it is indicated that all types of geosynthetics have been or can be used in dams to perform...

Fast Foundation for Soft Clay
This article describes the detailed foundation work and high-capacity piling design for a flue gas desulfurization (FGD) retrofit system for the Lambton Generation Station in Ontario,...

Banking on a Bridge
Completing the geotechnical design for the approach embankments and foundations for the Charter Oak Bridge, which crosses the Connecticut River between Hartford and East Hartford, Conn.,...

Modeling Bridge Abutment Stiffness for the Meloland Road Overcrossing
A simplified equivalent spring model representing the dynamic stiffness of a highway bridge abutment system is developed for use in seismic response studies. It is based on linear elastic...

Dynamic Soil-Foundation Interaction at the Meloland Road Overcrossing
Forced vibration tests, using a hydraulic ram device, were conducted on the Meloland Road Overcrossing (MRO) bridge over Interstate 8 near El Centro, California. Dynamic response data...

Seismic Analysis of Meloland Road Overcrossing Using Calibrated Structural and Foundation Models
A detailed seismic analysis of the Meloland Road Overcrossing is being implemented to study the response of this bridge during the 1979 Imperial Valley Earthquake. This analysis is based...

Predicting Turbine-Generator Foundation Vibrations
Two of the major considerations in the design of large turbine-generator foundations are to maintain the proper shaft alignment and to limit the vibration of the machine during operation....

Steel Alternates for the Hoover Dam Bridge
As input to the Environmental Impact Statement studies of appropriate long span bridges were performed for three alternate corridors across the Colorado River near Hoover Dam. Details...

Performance Monitoring of Concrete Structures with Embedded Sensors
This paper describes the use of embedded fiber optic sensors to monitor the performance of reinforced concrete structures. The fiber optic sensors are capable of measuring vibrations,...

Development in Criteria for Dam Corrective Actions
Reviewed is the recent history of the Bureau of Reclamation (Reclamation) Safety of Dams (SOD) Program. Particularly, the development of decision philosophies and technical approaches...

Jatiluhur Dam: Problems and Rehabilitation
The Jatiluhur Dam in Indonesia, completed in 1965, is an innovative design consisting of rockfill embankment with a clay core and a vertical cylindrical Intake Spillway. Within the Intake...

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....

Rock Structure in Relation to Concrete Dams on Granite
Granite is often considered to provide an excellent foundation for a concrete dam and a great many dams are thus founded on granitic rocks. Although granitic rocks lack the bedding of...

Numerical and Centrifuge Modeling of an Arch Dam on Jointed Rock
This paper addresses the stability of an arch dam built on highly fractured argillite. A large concrete thrust block combined with a wing dam forms the left dam abutment. The last FERC...

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...
