Model Study of Center Hill Fuse Plug Spillway
Model tests of a fuseplug spillway mounted on the fixed crest of an embankment dam were conducted to develop a satisfactory design that would fail in a orderly fashion at a prescribed...
Confirmation of Seismic Safety at Stafford Dam
A critical aspect of the North Marin Water District's mission to maintain reliable water supply facilities and water service is periodic assessment and re-evaluation of the seismic safety...
Overmining Causes Undermining(
Instream aggregate mining has caused significant problems and expense to California bridges. Riverbed degradation on the order of 3-5 m (9-15 ft) beneath waterway crossings within actively...
Large-Scale Embankment Overtopping Protection Tests
The U.S. Bureau of Reclamation (Reclamation), Colorado State University (CSU), and the Electric Power Research Institute (EPRI) have an ongoing cooperative research effort to determine...
Progressive Failure of an Overtopped Embankment
The failure of an overtopped embankment is a problem of a very complicated nature. Concerned organizations are interested in information that can be used in future planning and development...
A New Type of Concrete Trapezoid Dam
A new type of 128.0 m height concrete trapezoid dam (t-d) has been built for the Wunana Town Hydroelectric Power Station (WTHPS). The paper presents its optimum section design, several...
Assessing the True Value of Flood Control Reservoirs: The Experience of Folsom Dam in the February 1986 Flood
Over the last 40 years considerable public investments have been made in large flood control storage reservoirs throughout the U.S. and internationally. These projects were typically designed...
Uncertainty of Bridge Scour Estimates
Pier scour is the erosion of a streambed in the vicinity of bridge pier foundations. In this paper, fuzzy regression is used to develop two pier scour models, one based on crisp laboratory...
Simulation of 3D Free Surface Flows in Hydraulic Structure with Submerged Flow Passages
This paper presents primarily the results of an application of the newly refined computational simulation model to study three-dimensional flows in a lock and dam system, which has submerged...
Bending of Retrofitted Test Foundation Walls
New repair methodology has been developed for residential construction that can be used to retrofit foundation bearing walls damaged by mine subsidence. The repair strengthens the foundation...
RCC: Rehab Results
Thirty dams have been modified with roller compacted concrete in order to provide additional spillway capacity and for safe overtopping of embankment dams. In the national dam safety inspection...
Application of Digital Image Processing in Morphological Analysis of Geotextiles
Geotextile filters are rapidly replacing graded granular filters in dams, landfills, edge drains, and retaining walls. The design of these filters requires morphological information about...
Design and Construction of the Miami Metromover Extensions
Final design, right-of-way acquisition and construction of two extensions to the existing Downtown Miami Automated People Mover, known as the Metromover, began in September 1989. Millions...
Pin Piles Save Silos
The United Grain Corp. annually ships about 200 million bushels of wheat and other grains to destinations around the world from its leased facility on the Columbia River at Vancouver,...
Use of Pressuremeter in Mixed Highrise Foundation Design
The pressuremeter has been used extensively for the evaluation of strength and deformation characteristics of the glacial hardpan soils in the design and construction of caisson foundations...
Piles for Marquette University Math Building
This paper presents a comparison of static pile capacity predictions using CPT cone resistance results with results of a test pile program and production pile driving. Pile capacity prediction...
3-D Deformation Analysis of Pile Groups During Wave Loading
Deformation predictions of pile group supporting one leg of Magnus platform were conducted using the 3-D nonlinear computer program SPLICE (Structure/Pile/Soil Interaction Analysis) and...
Evaluation and Monitoring of Pile Performance Using Dynamic Measurements in Supporting Offshore Structures
The installation of offshore platforms into deeper waters and new environments is accompanied by an increasing uncertainty in the structure response, foundation design and performance....
A Centrifuge and Analytical Study to Evaluate Suction Caissons for TLP Applications in the Gulf of Mexico
This paper documents the results of a combined centrifuge and analytical study to evaluate the behavior of steel suction caissons under loading and soil conditions typical of deepwater...
Behavior of Suction Piles in Sand
In the marine environment, use of suction pressure for the installation of sealed top piles (suction piles) is a promising alternative to driven pile foundations, particularly in deep...
