摘　　要：在总结可恢复性相关研究的基础上,给出了桥梁可恢复性的概念。通过研究,提出了基于桥梁构件脆弱性曲线及修复加固方法,可以同时考虑恢复时间和初建时间的可恢复性评价方法,并建议了可恢复能力评价的标准。以一座多跨混凝土连续梁桥为例进行了算例分析。Based on the summary related to the resilience research achievements,this paper presents the concept of bridge seismic resilience. Though the deep study,the seismic resilience assessment method is proposed on account of bridge components vulnerability curves and bridge-reinforced and retrofit approaches. To reflect the efficiency of seismic resilience,both restoration time and initial construction time is considered in the seismic resilience equation. A multi-span reinforced concrete continuous bridge is analyzed to discuss the characteristics of the method in this paper.
