论桥梁震害成因及抗震加固方法
|
摘要
桥梁是保证交通运输畅通的重要环节,部分桥梁位于地质地形较特殊的区域,一旦地震发生,桥梁结构将会出现比较大的损坏,给人员和财产造成重大影响。鉴于此,分析公路桥梁震害成因及破坏形式,并提出桥梁抗震加固方法,以尽可能避免或减轻地震灾害对桥梁造成的破坏。
Bridge is the important link to guarantee the smooth of traffic and transportation.Some bridges locate in the areas with special geology and topography.When the earthquake occurs,the bridge will be damaged greatly and it has a significant impact on people and property.Given this,the seismic damage causes and modes of highway bridge are analyzed,the seismic reinforcement measures are put forward,in hope of avoiding or mitigating the damage on bridge by seismic.
