地震对桥梁的危害、抗震措施及结构振动控制

针对桥梁在地震中暴露出来的薄弱环节,通过慎重选择桥位,并对结构的薄弱部位予以局部加强,来提高桥梁的抗震能力。国内外多次地震经验证明,只要桥梁能满足场地有利、结构合理、整体性强、施工质量良好和措施得当,一般均能提高桥梁结构的抗震防灾能力。

Earthquake Damage to Bridge,Aseismatic Measures and Structural Vibration Control

On account of weak link of bridge exposed in earthquake,earthquake experience at home and abroad demonstrate that the bridge should be with aseismatic and disaster prevention capacity as long as the bridge can meet the requirements of advantageous site,reasonable structure,strong wholeness,good construction quality and appropriate measures.Improve the aseismatic capacity of the bridge by carefully selecting the bridge location and partially strengthening the weak part of the structure.
