隔振沟 meaning in English

isolation trench
vibration isolate ditch

So the solution is obtained by ansys . at those places with excessive vibration along the lightway , two field measures ( wave impending block and isolation trench ) were adopted to reduce vibration
并在振动较大的地方采用了wib ( waveimpendingblock )和隔振沟两种减振措施，同时对减振效果进行了分析比较，得到了较为理想的结果。
So ansys is applied here to calculate the response of ground under moving loads in light railway system . at the locations with the big vibration , two measures for vibration - diminishing ? wave impeding block and open drain for isolating vibration are constructed , and the effective of vibration - diminishing is analyzed
因此在计算轻轨列车荷载作用下地基土的响应时，本文运用ansys软件进行模拟，在振动较大的地方采用设置阻波区( wib ， waveimpedingblock )和隔振沟两种减振措施，同时对减振效果进行分析比较，得到了较为理想的结果。
