摘要
城市高架轨道系统会引起环境振动,影响人们的工作和学习.首先使用有限元法建立车辆-轨道-桥梁有限元模型,求得列车通过高架轨道时桥墩对大地的动力作用;再使用大型通用有限元程序ANSYS建立蜂窝波阻块-大地耦合振动计算模型,对蜂窝波阻块的隔振效果进行了分析.研究表明:蜂窝块波阻块作为一种地屏障结构,能够很好的隔离由高架轨道引起的大地振动.
Along with the city scale expanding, the traffic jam is more and more serious. The viaduct track system can alleviate urban transportation pressure.. However, the viaduct system can cause environment vibration and interfere with people＇ s work and study. By means of FEM calculate pier force from Viaduct System and finite element software ANSYS, environment vibration isolation effects of honeycomb WIB in viaduct track system is studied. Honeycomb WIB has good effects on vibration isolation effects.
