摘要
顺应桥梁施工技术的发展趋势,同时为了能够给工程应用提供合理建议,本文以实际工程为依托,设计了两个缩尺模型,研究承插接触面粗糙处理和承插接触面光滑处理对桥墩抗震性能的影响。分别对试件的加载过程、滞回特性、骨架曲线、耗能水平、残余位移和裂缝发展等方面进行描述和比较讨论。试验研究结果表明,当加载等级较低时,两个桥墩的性能区别不大;当加载等级较高时,不同接触面的影响有所显现,且粗糙接触面的桥墩的性能更优。
It complies with the development trend of bridge construction technology and provides reasonable suggestions for practical application.Based on the practical engineering,two scale models are designed to research the influence of rough contact surface and smooth contact surface on seismic performance of pier.The loading process,hysteretic characteristics,skeleton curve,energy dissipation,residual displacement and cracking development are discussed.The result shows that there is little difference in the performance of the piers when the loading grade is low,and the effect of different contact surfaces works when the loading grade is high,at the same time the piers with rough contact surfaces have better performance.
