[WIB Construction Method Case Study] Railway Vibration Mitigation for Residential Areas Along Railways, January 2017, Saitama Prefecture
Measures were implemented directly beneath the residence! Dominant vibrations in the 10-20Hz range have been reduced by 6-12dB!
Some plots of a residential development in Saitama Prefecture face a railway, raising concerns about the impact on the living environment after the construction of the houses. Therefore, the 'WIB method' was implemented directly beneath the houses. Vibration measurements were conducted before and after the countermeasures. Dominant vibrations in the range of 10 to 20 Hz were reduced by 6 to 12 dB (to 1/4 to 1/2 of the original vibration), keeping the vibration level below 60 dB. 【Case Overview】 ■ Location: Saitama Prefecture ■ Client: Housing manufacturer ■ Vibration source: Railway vibrations ■ Preservation target: Houses along the railway (total of 9 buildings; 5 buildings + 4 buildings) ■ Countermeasure work: Plate-type WIB method (honeycomb cell type) ■ Installation position: Directly beneath the receiving side *For more details, please refer to the PDF document or feel free to contact us.
