摘要:
圆端形板式桥墩是我国铁路客运专线主要采用的桥墩形式之一,对于我国这样一个地震多发区,研究其抗震性能具有十分重要的理论意义和应用价值.在回顾国内外研究土-结相互作用问题的基础上,以客运专线圆端形板式桥墩为研究对象,引入了FEMA440中推荐的改进的等效非线性化方法,介绍了考虑SSI的能力谱方法的应用步骤,对比了非线性时程分析与能力谱方法的计算结果.结果表明,此方法适用于基于位移的抗震设计方法,场地土的变软会加剧SSI的作用,地震能量耗散也相应增加
Abstract:
Round-ended plate pier is one of the most popular forms used in Chinese passenger dedicated railway line PDRL here after. It is well known that China is a country with much active earthquake. Studying the seismic behavior of this pier has a lot of theoretical significance and practical value. By taking round-ended plate piers of PDRL as the research object, this paper introduces the improved equivalent linearization method recommended by FEMA440and the application procedure of considering SSI based on capacity spectrum method reviewing the research of SSI at home and abroad, with discussion on the differences of the analytical results between the nonlinear time-history analysis and the capacity spectrum method. Results indicate that this method is suitable for the displacement-based seismic design method, the soft soil will increase the role of the SSI, and the seismic energy dissipation will also be increased
