Study on the Mechanism of Local Scour Around Bridge Piers

Journal of Marine Science and Engineering
Local scour around bridge piers poses significant challenges to the stability and safety of bridge structures. Local scour results from the combined effects of increased longitudinal flow velocity, the direct impact of the flow in front of the pier, and ...

Studying the effect of partial blockage on multi-vents bridge pier scour experimentally and numerically

Ain Shams Engineering Journal, 2018
The local scour depth at bridge supports due to partial blockage on front of multi-vents bridge pier is studied experimentally and numerically. The existence of blockage such as debris and industrial wastes, leads to increase the local scour depth around

Experimental Study on Local Scour at the Monopile Foundation of an Offshore Wind Turbine under the Combined Action of Wave–Current–Vibration

Journal of Marine Science and Engineering
Monopile foundations are the most widely used offshore wind turbine foundations. The experiments were conducted to investigate the influencing factors of local scour around the monopile under the action of wave–current–vibration.

Deformation Analysis of Large Diameter Monopiles of Offshore Wind Turbines under Scour

Applied Sciences, 2020
The displacement of monopile supporting offshore wind turbines needs to be strictly controlled, and the influence of local scour can not be ignored. Using p–y curves to simulate the pile–soil interaction and the finite difference method to calculate ...

Numerical study of local scour effects on the lateral pile-soil interaction

, 2016
Local scour usually occurs around offshore pile foundations, which may bring the reduction of both the effective stresses in the surrounding soil and the effective pile embedment. Until now, the effects of local scour on the lateral pile-soil interaction

Local scour at wide bridge piers

, 2014
Laboratory data for local scour depth at the size of wide piers are presented. Clear water scour tests were performed various pier widths (0.06, 0.076, 0.102, 0.14 and 0.165 m), two type of pier shapes (circular and rectangular) and two types of uniform ...
