Preliminary Studies of Pressure Flow Scour
Bridges that become inundated during floods have slightly pressurized flow that impacts bridge piers and creates an aggravated scour condition. Results of two preliminary laboratory studies...
The Influence of Exposed Footings on Pier Scour Depths
Data compiled from past test efforts are combined in this article with the results of two new flume test studies. The combined material, presented graphically, suggests a method for adjusting...
Threats to Bridge Stability from Scour Related Failures of Drop Structures
Catastrophic failure of bridge foundations may occur when channel bed elevations are lowered unexpectedly. Bridges to be constructed in channels that are known to have bed degradation...
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...
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...
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...

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...
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...
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...
Bi-Directional Load Testing of Shafts to 6000 Tons
This paper describes the use of Osterberg cells (O-cells) to perform bi-directional load testing on full size production drilled shafts for a major bridge foundation near Owensboro, Kentucky....
HUD Concerns: Post-Tensioned Foundations in Texas
An investigation was conducted of post-tensioned slab foundation systems in Texas pursuant to a request from the Headquarters Office's of the U.S. Department of Housing and Urban Development...

Bridge Scour Analysis in New Jersey: Which Scour Factors Matter Most?
This paper seeks to correlate the scour susceptibility of bridges with such observable characteristics as bridge design features, waterway characteristics, and geographic and geologic...
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...
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...
Foundation Uniform Pressure and Soil Structure Interaction
The enclosed paper was presented in the ASCE, 8th Conference on Computing in Civil Engineering and published in its proceedings. One of its main assumptions was considering the foundation...
Mathematical Modeling of Airport Pavements
Theories for analyzing rigid pavements are presented. The emphasis is on the choice of the proper models for the pavement and for the subgrade, and on the correct mathematical formulation...
