Article Preview

In this paper, an exploration was presented to access the actual screening effectiveness of concrete wave impeding block (WIB) and the influence of WIB embedded depth on the vertical vibration isolation effect under the continuous vertical loading. Furthermore, the displacements of measuring points were simulated with a semi-analytical boundary element method (BEM) and validated by the measured records. It was found that a concrete WIB with a reasonable embedded depth was able to decrease the ground vibration greatly. It was also proved that decreasing the embedded depth was an efficient measure for WIB to reduce the dynamic response of ground. Besides, the good qualitative agreement between the calculation and the experiment proved the reliability of the numerical method.
