摘要

地下铁路行车速度的提高对车致环境振动的控制提出了更高的要求。本文围绕350 km/h高速铁路隧道行车诱发的振动问题开展研究。基于车辆—轨道耦合动力学理论和有限元方法，构建了地下铁路车致振动预测模型，并通过现场振动试验验证其准确性。通过数值计算详细探讨了波阻板宽度、埋深和材料属性对隔振性能的影响。研究表明：隧道上方土体中设置水平波阻板可显著降低行车引发的地面振动。特别地，波阻板布设位置靠近振源较近时，对5 Hz以上的振动成分呈现出显著的隔振效果。同时，波阻板宽度、埋深与其隔振性能直接相关，但过大的宽度和埋深可能导致远场地面振动增强；多孔聚苯乙烯波阻块相较于橡胶、细砂及C30混凝土展现出最佳的隔振性能，特别是在5～200 Hz的振动频率范围内有较好隔振效果。

Abstract

he increasing speed of underground railways necessitates posed higher demands for controlling train-induced environmental vibrations. This study focuses on the vibration issues induced by trains running in tunnels at 350 km/h. Utilizing the vehicle-track coupled dynamics theory and finite element methods, a prediction model for train-induced vibrations in underground railways was built and subsequently validated through on-site vibration tests. The study comprehensively examines the influence of the width, depth, and material properties of wave impeding blocks (WIB) on vibration isolation performance. Results indicate that installing horizontal WIBs in the soil above tunnels significantly reduces ground vibrations caused by train movements. Notably, WIBs positioned close to the vibration source offer prominent isolation effects for vibrations above 5 Hz. The width and depth of the WIB directly correlate with its vibration isolation capability, though excessive dimensions may amplify distant ground vibrations. Among evaluated materials, porous polystyrene WIBs outperform rubber, fine sand, and C30 concrete in terms of vibration isolation, especially within the 5-200 Hz frequency range.
