桥梁设计中隔震设计的重要性 　　论文关键词：桥梁设计　隔震设计 Paper keywords: isolation design of bridge design 　　论文摘要：近年来我国城市交通事业迅猛发展，桥梁在城市发展中的作用日益显现和提高，因此客观上要求桥梁抗震效能的增强与改善。本文从三个方面来介绍桥梁设计中的隔震设计：第一部分强调了加强桥梁隔震设计的重要性，第二部分介绍了桥梁隔震设计的相关理论，在第三部分着重介绍了桥梁隔震设计的方法。 Abstract: in recent years the rapid development of urban traffic in China, a bridge in a more important role in urban development and improve, thus is necessary for bridge seismic performance of strengthened and improved. This article from three aspects to introduce the aseismic design of bridge design: the first part emphasizes the importance of strengthening bridge isolation design, the second part introduces the theory about the design of bridge isolation, in the third part emphatically introduces the design of bridge isolation method. 　　桥梁是现代城市化建设中的重要基础设施，它具有极强的社会公共性，建设时其投资较大且后期运营管理中也相对困难。另外桥梁作为危机管理系统的重要构成部分，应当具备较强的抗震性能，因为桥梁抗震性能的提高可以有效地减少地震后的损失。 Bridge is an important infrastructure of modern urbanization construction, it has extremely strong social public, when its construction investment is larger and the late operation management is also relatively difficult. Another bridge as the important part of the crisis management system, should have better seismic performance, because the bridge seismic performance improvement can effectively reduce earthquake damage. 　　1 桥梁进行隔震设计的好处和重要性 1 the benefits and the importance of bridge vibration isolation design 　　1.1 桥梁隔震设计的重要性 1.1 the importance of bridge seismic isolation design 　　桥梁设计中的隔震设计指的是在桥梁建设时安装隔震器，它可以使桥梁在水平方向上得到柔性支承，这样就使水平方向上的周期延长，另外还要安装阻尼器来，这样做是为了提高桥梁的阻尼效应，可以再地震发生时降低地震的作用。 Bridge in the design of vibration isolation design refers to the installation of isolation device in bridge construction, it can make bridge is a flexible supporting on a horizontal direction, thus prolongs the period that horizontally, in addition to install dampers, this was done in order to improve the damping effect of bridge, can reduce the earthquake effect at the time of the earthquake. 　　近些年,国外一些发达国际在桥梁的隔震设计方面加强了研究
