既有桥梁体系抗震加固方法探讨
|
摘要
与我国现行桥梁抗震设计规范中对桥梁抗震性能的要求相比较,当前我国大多数在役公路桥梁存在不同程度的抗震能力不足问题,导致我国目前公路网中桥梁的抗震能力较弱,一旦灾害性地震发生,直接和间接经济损失巨大,无法满足预期抗震性能要求,开展既有桥梁抗震加固的研究迫在眉睫.为此,在分析我国既有桥梁建造年代和抗震设计特点的基础上,结合震害揭示的桥梁易损部位,从桥梁结构体系角度出发,探讨经济、有效的抗震加固方法,以促进我国桥梁抗震加固技术的发展.
Compared with requirements of the seismic performance of bridges under the current seismic codes for bridges design,the current majority of bridges in-service roads have seismic deficiencies in different levels.These deficiencies had an adverse impact on the performance of bridges of road network,once the disastrous earthquakes occurs,the direct and indirect economic losses is very huge,and it is unable to meet the expected seismic performance requirements,so the study of seismic retrofit of existing bridges is imminent.In this paper,based on the basis of investigation of the existing bridge building’s history,seismic design features and vulnerable component of bridge under earthquake,from the point of view of the bridge structure system,we investigate many of economic,effective retrofitting measures,and promote the development of seismic retrofitting technology for bridges.
