摘要
迅速发展的高速铁路带来方便的同时也会对周围地基造成振动影响,对于以排桩作为隔振措施的研究目前多处于理论分析阶段。本文将列车行驶引起的荷载等效成可以应用在有限元计算中的Fourier表达形式,并应用ABAQUS软件建立了排桩隔振系统的三维有限元计算模型。应用控制变量法分析桩长、桩间距、桩身材料、双排桩距离和交叉布置排桩对隔振效果的影响,为施工设计提供依据。
While rapid development of high-speed railways brings convenience,it also causes vibra-tion impacts on the surrounding ground that need to be mitigated.The study of using driven piles as a vibration isolation method is almost in the stage of theoretical analysis.In this article,the train load is represented by the Fourier expression form that can be used in finite element calcula-tion,and the three-dimensional piles vibration isolation model is created with ABAQUS finite ele-ment software.The different factors of the vibration isolation effect are analyzed using the control variable method,and these factors include the pile length,spacing,material,double row distance, and arrangement.The results can provide the basis for a construction design.
