[WIB Construction Method Case Study] Railway Vibration Countermeasures for Residential Areas Along Railways H29.2-3

Keep the vibration level below 60dB! To ensure greater vibration reduction, measures will be implemented directly beneath the unused land!

Some plots in a residential development area in Saitama Prefecture face a railway, raising concerns about the impact on the living environment after the construction of houses. Therefore, the "WIB method" was implemented directly beneath the houses. Additionally, to ensure greater vibration reduction, countermeasures were also implemented directly beneath the unused land. Vibration measurements were conducted before and after the countermeasures, resulting in a reduction of dominant vibrations in the 10-20Hz range by 10-14dB (to 1/5 to 1/3 of the original vibrations), keeping the vibration level below 60dB. [Case Overview] ■ Location: Saitama Prefecture ■ Client: House manufacturer ■ Vibration source: Railway vibrations ■ Preservation target: Residential buildings along the railway (a total of 4 buildings + unused land) ■ Countermeasure works: Plate-type WIB method (directly beneath the houses) and wall-type WIB method (directly beneath the unused land) honeycomb cell type ■ Construction position: Directly beneath the receiving side (beneath the houses) and along the propagation path (beneath the unused land) *For more details, please refer to the PDF document or feel free to contact us.
