HONEYCOMB-WIB FOR MITIGATION OF TRAFFIC-INDUCED GROUND VIBRATIONS WHEN CONSTRUCTED AROUND VIADUCT FOUNDATION

Abstract

The authors investigated that a honeycomb-WIB (Wave Impeding Barrier of honeycomb celles) works for vibration mitigation for the traffic induced vibrations from viduct 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 demonstrate the superiority of the honeycomb-WIB, claimg the reduction more than several dB at the low frequencies.
