摘　　要：地铁引发的环境振动问题日趋严重,探索符合生态经济原则的绿色减振技术变得紧迫。本研究从城市景观要素入手,探讨城市水域地形对振动传播的潜在影响。通过构建缩尺比1∶20的土-地铁隧道模型箱,展开了基于水域地形条件的振动传播试验,以平坦地表的振动响应作为参照,探究了水域地形对振动衰减的作用,并评估了不同水体深度对地铁振动传播特性的影响。试验结果表明,水域地形在降低地表振动加速度峰值方面效果显著,并且这种衰减效果随着水体深度的增加而增强。这一结论为未来城市规划中控制地铁减振提供参考,通过合理布置水域地形,能够在减振的同时美化环境,推动城市可持续发展。The environmental vibration issues caused by subway operations are becoming increasingly severe,and the exploration on green vibration reduction technologies that align with ecological and economic principles has become urgent.This paper begins with urban landscape elements and thoroughly investigates the potential impact of urban water terrain on the propagation of vibrations.By constructing a 1∶20 scaled soil-subway tunnel model box,vibration propagation tests under water terrain conditions were conducted,with the vibration response of a flat surface serving as a reference.The paper explored the vibration attenuation effect of water terrain and evaluated the impact of different water depths on the propagation characteristics of subway vibrations.The test results indicate that water terrain significantly reduces the peak values of surface vibration acceleration,and this attenuation effect is enhanced with increasing water depth.This conclusion provides a reference for controlling subway vibration reduction in the future urban planning.By strategically arranging water terrain,it is possible to reduce vibrations while beautifying the environment and promoting sustainable urban development.
