Study on anti-tsunami optimization design of bridge pier: A new type bridge pier

Ocean Engineering, 2020
Abstract The surface of the bridge pier is divided into upstream surface and downstream surface. The tsunami force characteristics and generation mechanisms for regular piers, i.e. square, circular and diamond piers, as well as pressure distribution and flow field around piers are discussed.

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 ...

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.

Foundation Depth for Bridge Piers

Journal of The Institution of Engineers (India): Series A, 2013
The safety of bridge piers built in rivers having the bed is one of the prime aspects in the study of scouring process around bridge piers. The stability of bridge piers depends on the depth of foundation provided below maximum scour level. The stability analysis of bridge piers is carried based on moment of forces acting on the caisson pier when the ...

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.

Vehicle Collision with Bridge Piers

Journal of Bridge Engineering, 2005
Inelastic transient finite element simulations are used to investigate the demands generated during collisions between vehicles and bridge piers. Such collisions have occurred in the past, sometimes with catastrophic consequences. Two different types of trucks and two different bridge/pier systems are used in the simulations.
