A Study on Using Infilled Trenches for Vibration Reduction of Underground Structures by Train Loading
초록
Installing vibration isolation in structures, such as structures adjacent to subways, may be delicatebecause of the proximity with the vibration source or because of the wave propagation path. This paper discusses on method that install isolation Pads on underground walls as a part of the vibration mitigation system, and also on its efficiency, The proposed method is proven to affect significantly the distribution of acceleration in the neighborhood of the structure and to reduce efficiently the maximum amplitude of the vibration. It is also seen that installing isolating pads until the depth of the foundations and deeper is more efficient than installing such device separately from the structure. This Study being limited to the comparison of installation methods, further Studies considering the thickness, stiffness and other parameters should be required.
