空沟、填充沟屏障隔振性能研究
Study on the Vibration Isolation Performance of Open Trench Barrier and Filled Trench Barrier

对空沟、填充沟屏障隔振进行了较为系统地研究，对比研究了空沟沟长、沟宽及沟深变化对隔振性能的影响，并对填充沟不同填充材料的隔振性能差异进行了研究，对实际工程中的屏障隔振设置及参数优化具有一定的指导作用。
The vibration isolation of open trench barrier and filled trench barrier is systematically studied, the influence of the change of length, width, and depth of open trench barrier on the vibration isolation performance is compared, and the difference of vibration isolation performance of different filling materials of filled trench is studied, which has a certain guiding role for the barrier vibration isolation setting and parameter optimization in practical engineering.
