针对高速公路产生的低频环境振动，以公路旁排水沟为研究对象，深入研究其对环境振动的隔振效果。采用大型有限元通用软件 ANSYS ，通过建立排水沟-路面-土三维模型，模拟分析排水沟深度、宽度以及沟内水位、沟壁填充对隔振效果的影响。结果表明：设置排水沟后有明显的隔振效果，改变沟宽沟深对隔振效果影响不大；沟壁填充混凝土的排水沟比无混凝土的隔振效果好；排水沟中有水的工况比无水的工况隔振效果好。

According to the environmental vibration with low frequency produced by express highway and taking the drains beside the express highway for object ,the isolation effect of the drains for environmental vibration is studied deeply .The finite element software ANSYS was used to build a 3-D model including drains ,pavement and soil .Through the model , the impacts of the drains’ depth ,width ,level and wall on the isolation effect were simulated and analyzed .The results suggest that setting the drains has obvious effect of vibration isolation ,and changing the drains’ depth and width has little impact on the isolation effect ;The trench wall padding with concrete is better than that without concrete in the isolation effect ;The drain with water is better than that without water in the isolation effect .
