[WIB Construction Method Case Study] Railway Vibration Countermeasures for Residential Areas Along Railways, September 2018, Saitama Prefecture

Concerns about the impact on the living environment after residential construction! Introducing examples aimed at increasing vibration reduction effects!

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. In buildings D and E, where the vibration level exceeded 70dB before the measures were taken, the countermeasures were extended on the railway side to enhance the vibration reduction effect. After conducting vibration measurements before and after the measures, the dominant vibration at 10Hz was reduced by 6dB to 14dB (to 1/5 to 1/2 of the original vibration), successfully keeping the vibration level below 60dB. 【Case Summary】 ■ Location: Saitama Prefecture ■ Client: Housing manufacturer ■ Vibration source: Railway vibration ■ Preservation target: Residential buildings along the railway (total of 5 buildings) ■ Countermeasure: Plate-type WIB method (honeycomb cell type) ■ Installation position: Directly beneath the receiving side (partly on the propagation path) *For more details, please refer to the PDF document or feel free to contact us.
