Abstract: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.
