ABSTRACT
The authors demonstrated that a honeycomb-WIB (Wave Impeding Barrier of honeycomb cells) works for vibration mitigation for the traffic induced vibrations from viaduct when constructed to surround the foundation, especially in the low frequency range. The thin layered method is taken to analyze the involved wave field to determine the size of the WIB cells and their area for construction. The interaction of structure-foundation-soil is analyzed by the 3D substructure method to show the WIB effect for the ground response reduction. The comparison with the buried wall for an alternative measure demonstrates the superiority of the honeycomb-WIB, clamming the reduction more than several dB at low frequencies.
