基于二次刚度的新型桥墩快速修复加固方法研究
|
摘要
为快速修复地震引起的损伤桥墩并提高其力学性能,对现有的修复加固方法,如增大截面法、粘钢加固法、纤维增强复合材料(FRP)加固法、预应力加固法、外包套管法、植筋加固法和以上几种方法的复合修复加固法进行了述评.提出基于二次刚度新型桥墩的快速修复加固方法,研究发现,所提修复加固方法比现有的修复加固方法更快、更贴近实际应用.指出结合实际震后工程的快速、可靠、简单的修复加固技术是未来的发展趋势之一.
To repair the earthquake-induced piers rapidly and improve the behaviors of such piers,this paper proposes a rapid repairing and reinforcement method for a novel bridge pier with post-yield stiffness after commenting on the existing repair and reinforcement techniques,i.e.increased cross-section reinforcement method,bonding steel reinforcement method,FRP reinforcement method,prestressed reinforcement method,jacket reinforcement method,additional bars reinforcement method and composite reinforcement method.It can be found that the proposed method is faster and more practical than the existing repair and reinforcement methods.And then it is pointed out that one of the trends of repair and reinforcement techniques will be rapid,reliable and simple technique for earthquake damaged bridge piers.
