通载浮桥的水弹性响应分析

Overview on hydroelastic response analysis of floating bridges

浮桥具有重要的军事用途,在民用上也已受到越来越广泛的重视。为了使浮桥的设计既安全又经济,就必须对浮桥的载荷和强度有一个比较精确的评估。浮桥载荷具有移动性,并可能同时遭受风、浪、流联合作用,浮桥在这些载荷联合作用下的动响应分析在理论上将是一个很具挑战性的问题。通过资料的收集和整理,对国内外相关研究的现状作了介绍,并指出了研究的主要方向。

Floating bridges, which have important military application, have also received increasing attention for its civil usage. To keep the design of floating bridges safe and economical, a relatively precise evaluation on the bridges′ loading capacity and strength is necessary. Since the loads on the floating bridge are movable and the bridge may be employed under adverse conditions and the combined negative impacts inflicted by wind, wave and current, the dynamic response analysis of the floating bridge against those loads still remains a theoretic challenge. In this paper an overview is carried out on the latest development in the study of hydroelastic response analysis of floating bridges. Through thorough investigation and information gathering and analyses, the key technical problems that need to be tackled can be further understood in the future study, which could lay a solid foundation for the research work.
