| 摘 要： | 运用弹性边界元法和饱和土半解析边界元法计算分析连续屏障的远场隔振效果,并对两种地基条件下的隔振情况进行对比。结果表明:空沟深度对隔振效果影响较大,而空沟宽度对隔振效果基本没影响,弹性地基中空沟的隔振效果要好于饱和地基。填充沟宽度较小时,两种地基中的填充沟隔振效果基本相同,随填充沟深度和剪切模量的增加而提高;而当填充沟宽度较大时,弹性地基中的填充沟隔振效果要远好于饱和地基的情况。

| Abstract: | This paper presents a study on the vibration isolation efficiency of continuous wave barriers,including open trench and in-filled trench,as passive barriers in elastic foundation and saturated foundation,respectively.The investigation is accomplished using elastic BEM and the semi-analytical BEM.The effect of the model parameters on the effectiveness of vibration isolation by open trench and in-filled trench is investigated and discussed in detail.The results show that the depth of open trench can affect th... |
