Rehabilitation of Cracked Embankment Dams
Cracking is a common phenomenon in many earth embankment dams and especially those small to medium size dams constructed on compressible soil foundations. Collapsible soil conditions,...
The Stabilization of Concrete Dams by Post-Tensioned Rock Anchorages: The State of American Practice
Permanent post-tensioned rock anchorages have been used for over twenty years in America to stabilize existing concrete dams and their appurtenant structures. This paper provides a state...
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...
Seismic Rehabilitation of Earth Dams
The purpose of this paper is to present methods available for engineered remediation of seismically deficient earth dams (not including tailings dams), review their strengths and weaknesses,...
Liquefaction Potential of Gravelly Soils in Dams
Gravelly soils are common components of embankment dams and their foundations. When such soils have been placed or deposited in a loose condition and are saturated, they are potentially...
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...
Remedial Works at Troneras and Miraflores Dams in Colombia
The 38 m high Troneras and the 55 m high Miraflores earth dams were built in the period 1959-1965. The dams are composed of residual soils and founded on a deep residual overburden. Significant...
Rehabilitation of a Toe Drain
Old or improperly designed toe drains can cause trouble for embankment dams. Toe drains installed without proper filtering can provide an easy course for internal erosion and piping of...
The Use of Post-Tensioned Anchorages on the Arch Portion of Stewart Mountain Dam, Arizona
Post-tensioned rock anchorages were selected by the Bureau of Reclamation (Reclamation) to stabilize Stewart Mountain Dam against potential seismic loadings. The use of such anchorages...
Seismic Stability Modification Designs for Embankment Dams
The Bureau of Reclamation (Reclamation) has recently designed rehabilitations for four embankment dams to ensure their seismic stability. A fifth project is scheduled for construction....
Seismic Rehabilitation of Sardis Dam
Extensive subsurface investigation of the embankment dam revealed the existence of a weak layer of silt and soft clay in the original topstratum clay underlaying the upstream shell of...
Seismic Stability Modification Requirements for Pineview Dam
Pineview Dam is located 8 km upstream from Ogden, Utah, and about 8 km from the Wasatch Fault Zone. Preconstruction information and construction records available at the outset of the...
Using Innovative Technologies and Geosynthetics in Embankment Dam Rehabilitations
The ever increasing development and confidence in new and innovative technologies such as geosynthetics, in conjunction with often significant economic advantages, have led designers to...
Construction and Verification of Ground Improvements at Mormon Island Auxiliary Dam
Mormon Island Auxiliary Dam, part of the Folsom Dam and Reservoir Project near Sacramento, California, is founded on alluvial materials that were dredged and processed for gold on several...
Rehabilitation of the Deep Creek Lake Dam
This paper presents the rehabilitation design for upgrading the Deep Creek Lake dam. The Deep Creek dam is a rock fill dam, 92 feet (28 m) high and 1290 feet (393 m) long, and constructed...
Seismic Safety Modification of an Old Earthfill Dam
Chollas Dam was built as a water supply reservoir for the City of San Diego. The reservoir is no longer a part of the municipal water system but has been operated since 1966 as a recreational...

Dynamic Analysis of Beams on a Pasternak Foundation
Since many years pavement engineers apply very simple statical models to analyze their specific problems. The development of numerical tools and easily available computer power make much...
Using Finite Element Analysis to Derive the Coefficient of Subgrade Reaction
The coefficient subgrade reaction is a concept used to generate spring constants which are commonly used to model the foundation subgrade in the analysis of mat foundations. This paper...
Tutorial: Fuzzy Expert Systems
This extended abstract presents a brief introduction to a tutorial on fuzzy expert systems. The precepts of set theory and classical predicate logic are briefly reviewed to provide a foundation...
