线性荷载下排桩、空沟隔振特性试验研究

为了研究排桩、空沟的隔振效果的影响范围,通过试验研究的方法在线性荷载条件下对此进行了研究,结果表明：在线性荷载条件下,排桩可取得整体性的隔振特点,并且在不同的屏障前均出现了振动增强的情况；深度的增加可使得排桩、空沟的影响范围增加；随着屏障宽度的增加,排桩的影响范围呈现出了增长的趋势,而空沟则为整体下降的趋势。且空沟的影响范围降低程度相比于排桩较小；随着振源距的增加,空沟、排桩的影响范围均为降低趋势。

Test on Vibration Isolation Characteristics of Row Piles and Hollow Trenches under Linear Loads

In order to study the influence range of the vibration isolation effect of piles and hollow trenches, this method was studied under the condition of linear load through experimental research methods. The results show that under the condition of linear load, the overall vibration isolation characteristics of the piles can be obtained. In addition, the increase of vibration occurred in front of different barriers; the increase in depth can increase the range of influence of piles and empty trenches; as the width of the barrier increases, the range of influence of piles shows an increasing trend, and The empty ditch is a downward trend overall. In addition, the reduction range of the effect range of the empty trench is smaller than that of the row pile. With the increase of the vibration source distance, the impact range of the empty trench and the row pile are decreasing.
