摘　　要：介绍了国内目前钢筋混凝土(RC)空心桥墩的应用情况,系统梳理了国内外关于RC空心桥墩抗震性能的研究现状,包括拟静力试验、振动台试验、理论研究以及数值模拟方面的研究动态和取得的成果。总结了目前RC空心桥墩抗震性能研究存在的主要问题:反映空心桥墩截面特殊性的壁厚比、宽厚比等参数对其抗震性能的影响研究不充分;高墩、薄壁空心墩等大型空心桥墩抗震性能的研究不系统;采用新型结构形式与新材料的空心墩抗震性能研究不完善等。提出了针对上述不足之处开展深入研究的建议。In this paper,the real application of RC hollow piers in China is presented.Then,we systematically summed up the research status of the seismic performance of RC hollow piers at home and abroads,including the trend and the achievement in terms of pseudo static test,shaking table test,theoretical research and numerical simulation research,and summarized the main problems in current researches.Specifically,the researches on the influence of the wall thickness ratio and the width thickness ratio etc.on the seismic performance of RC hollow piers,and the seismic performances of large hollow piers such as high piers and thin-walled hollow piers etc.and hollow piers with new structural forms and new materials have certain limitations.These findings suggest that further research should be conducted aiming at these problems in the future.
