Bridge Pier Scour Countermeasures

World Environmental and Water Resources Congress 2007, 2007
Local scour at bridge piers is a potential safety hazard to the traveling public and is a major concern for transportation agencies. Bridge pier scour is a dynamic process that varies with water depth, flow angle, pier geometry and other factors.

Flow around Bridge Piers

Journal of Hydraulic Engineering, 1998
This paper presents the results of a laboratory study on flow past cylindrical piers placed on smooth, rough, and mobile beds. Experimental results are presented on the flow in the plane of symmetry, including the frontal downflow and the effects of bed roughness and the scour hole on it.

Windsor Bridge Pier Repairs

Practice Periodical on Structural Design and Construction, 1996
This paper discusses a bridge reconstruction project that included a most unusual repair of two main river piers. The bridge, built in 1935, is owned by Broome County, N.Y. and is located in the village of Windsor. It provides a two-lane highway crossing over the Susquehanna River.

Scour Vulnerability of River Bridge Piers

Journal of Geotechnical and Geoenvironmental Engineering, 2003
A simple procedure is proposed to assess the vulnerability of bridge piers in rivers, taking into account the phenomena governing fluvial dynamics during flood events. The procedure requires an estimation of the maximum scour depth of the soil surrounding both the pier and the foundation as well as an analysis of the bearing capacity of the pier ...

Behavior of Nonlinearly Restrained Slender Bridge Piers

Journal of Bridge Engineering, 1998
The load-carrying capacity of slender reinforced concrete piers depends on the horizontal retaining forces exerted by the bridge deck. The magnitude of these forces is a function of the behavior of the restraints connecting the deck to the piers and to the abutments, as well as of their evolution in the presence of increasing loads. A numerical method,

Impact of Upstream Bridge Pier on the Scouring Around Adjacent Downstream Bridge Pier

Arabian Journal for Science and Engineering, 2018
The study aspires to investigate a relative scour condition around three-pier group. It identifies the upstream downstream scour geometries when two tandem piers are placed inline and third pier is placed eccentrically in middle of tandem piers. Laboratory scale experiments were physically performed by gradually varying the intermediate longitudinal ...

Effect of Pier Spacing on Scour Around Bridge Piers

Journal of Hydraulic Engineering, 1985
Small scale experiments were designed to investigate effects of lateral spacing between bridge piers on scour depth. The scouring process is effected by two processes: (1) The interaction of the horseshoe vortices around the bases of the piers; and (2) the acceleration of flow between the piers.
