Wave Current Force Action and Foundation Scour of Marine Bridges

Abstract

With marine bridges extending to the deep sea, wave current force action and scouring on bridge foundations have become the main factors threatening bridge safety. To ensure the design rationality as well as construction and operation safety of bridges, this paper sorts out the major problems faced by marine bridges in terms of wave force action and foundation scour, and proposes that marine bridges should be developed in high-precision prediction method, environmental prediction and pre-warning systems, research on multi-factor coupling effect of environment, scour numerical simulation technology, and wave current force calculation method. Furthermore, countermeasures are proposed from the aspects of macroscopic management, industrial application, and academic technology.

Investigation of the Dynamic Performance of a Large-Span Suspension Bridge Influenced by Scouring Based on Vehicle-Bridge Coupled Vibration

“…Once damaged, the repair cost of a bridge is very large. Li et al organized the major problems experienced by marine bridges in terms of wave force action and foundation scour and proposed that marine bridges should be developed using high-precision prediction methods, environmental prediction and prewarning systems, research on the multifactor coupling effect of the environment, scouring numerical simulation technology, and wave current force calculation methods [10]. e overall response of a bridge to static and dynamic loads is influenced by the soil-foundation-structure interaction [11,12].…”
