Abstract

For two-and three-dimensional problems, the vibration isolation effect of barriers in the travel path of waves has been studied using a boundary element method in the frequency domain. The soil is modelled as a half-space or a layered medium. The results indicate that the effectiveness of a wave barrier is strongly dependent on its location and depth with respect to the vibration source and that the optimum values of these two parameters are sensitive to vibration frequencies.

2차원과 3차원모델에 대해 진동전파구간에 설치된 방진구의 진동차단효과가 주파수영역의 경계요소법에 의해 반무한영역지반과 충진지반에서 검토되었다. 연구결과는, 방진구의 효율이 진동원과 관련된 방진구의 위치 및 깊이에 큰 영향을 받으며, 그들의 최적크기는 진동주파수에 대해 민감한 것을 나타낸다.
