摇摆—自复位桥墩具有较好的抗震韧性，是桥梁地震工程研究的热点之一。对摇摆—自复位桥墩的研究和应用情况进行了系统总结，首先介绍了摇摆—自复位桥墩的基本概念、力学特征和分类，然后总结了工程应用与设计方法研究成果，分析了目前存在的问题与挑战，最后从基于全寿命周期理念的结构耐久性与可维护性设计，能同时满足正常使用与抗震需求的合理状态及其设计控制指标，以及与装配式桥梁柔性橡胶支座的结合等3个方面阐述了研究的应用前景。
Research,Application Status and Prospect of Rocking and Self-centering Piers
The rocking and self-centering piers have good seismic resilience,which is one of the focuses on bridge earthquake engineering research.The research and application of rocking and self-resetting piers are systematically summarized in this study.Firstly,the basic concepts and mechanical characteristics are introduced.Secondly,the rocking and self-centering piers are divided into three categories according to the structural characteristics and self-centering realization methods,and their research status is reviewed respectively.Then,the research results of engineering application and design methods are reviewed.Finally,the existing problems and challenges are summarized,and research prospects are described from three aspects:structural durability and maintainability design based on the life cycle concept,reasonable state and design control index that can meet the normal use and seismic requirements,and the combination with the flexible rubber bearings in prefabricated bridges,which provides reference for further research and application.
