Simulation of Scour at Bridge Supports
Građevinar, 2020 Groups of piers are used on bridges to minimise scour around bridge supports. The prediction of scour around piers due to interaction of vortices around bridge piers is more complex compared to scour prediction around a single pier.

Kinematic Response of Bridge Piers
Procedia Engineering, 2016 AbstractThis paper deals with the soil-structure interaction that occurs in deep foundations of bridge piers in seismic areas. In particular, the kinematic response of rigid caisson foundations under the passage of obliquely incident polarized shear waves is highlighted and discussed. A Winkler model with translational and rotational impedances is used

Bulbous Pier: An Alternative to Bridge Pier Extensions as a Countermeasure against Bridge Deck Splashing [PDF]
Fluids, 2019 Bridge deck splashing causes deterioration to a bridge’s structure and renders the bridge unsafe for motorists and pedestrians. The traditional countermeasure for bridge deck splashing has been pier extension. Pier extensions move the pier wave and the associated splash away from the bridge deck, but retrofitting existing bridges with pier extensions ...

Journal of Hydrology and Hydromechanics, 2020 Recent studies have shown that the presence of ice cover leads to an intensified local scour pattern in the vicinity of bridge piers. To investigate the local scour pattern in the vicinity of bridge pier under ice-covered flow condition comparing to that

The impact of bridge pier on ice jam evolution – an experimental study
Journal of Hydrology and Hydromechanics, 2016 The ice jam in a river can significantly change the flow field in winter and early spring. The presence of bridge piers further complicates the hydraulic process by interacting between the ice jam and bridge piers.

Predicting maximum scour depth around bridge abutment using M5 model [PDF]
علوم و مهندسی آبیاری, 2018 Scour around piers and abutments leads to a lot of bridge failures. Scouring around the bridge piers and abutments is one of the most important factors in bridge failure which happens over time and increases during floods, probably causing general damage

Log Jams at a Bridge with a Pier and a Bridge without Pier
Procedia Engineering, 2015 AbstractA flume experiment was carried out in a rectangular flume in order to investigate interaction between two different model bridges and logs from the viewpoint of flood disaster prevention. Logs is assumed representative of flowing wood during floods. The model bridge with a pier and model bridge without pier were used as an obstruction in rivers.

Ship-Bridge-Pier Protective Systems
Coastal Engineering 1980, 1980 This paper describes the analytical and experimental studies on the behaviors of a ship subjected to a sheering flow induced around a rectangular solid-type marine structure, and also deals with ship-structure protective systems against ship impacts. Large bridge piers, which are constructed in a narrow waterway with strong tidal currents, are treated ...

A numerical study of flood effect of a bridge at tail of Ganjiang River, entrance of Poyang Lake [PDF]
E3S Web of Conferences, 2020 The construction of a river-crossing bridge will have an impact on the flow movement of the river section, which will bring adverse impact on flood control.

Effect of Bridge Pier Shape on Scour Depth at Uniform Single Bridge Pier
Mehran University Research Journal of Engineering and Technology, 2018 L'affouillement de la jetée du pont peut entraîner la défaillance du pont et la forme de la jetée du pont elle-même est l'un des principaux facteurs de contrôle de l'affouillement autour de la jetée du pont. La quantité de sédiments qui est retirée de la limite de la jetée du pont est appelée affouillement de la jetée du pont et la profondeur jusqu'à ...
