[WIB Construction Method Case Study] Railway Vibration Mitigation for Residential Buildings Along Subway Lines

Support beams were also installed! We were able to keep the vibration level below 50dB!

In Tokyo, residential buildings are located close to railways that run underground, raising concerns about the impact of railway vibrations on the living environment after the construction of new homes. To address this, the 'WIB method' was implemented directly beneath the residences. Since building support was necessary, support piles were also installed. Vibration measurements were conducted before and after the implementation of the countermeasures, resulting in a reduction of vibrations by 12 to 17 dB (from 1/7 to 1/4), successfully keeping the vibration levels below 50 dB. 【Case Summary】 ■ Location: Tokyo ■ Client: Project owner ■ Vibration source: Railway vibrations ■ Preservation target: Residential buildings along the railway (underground) ■ Countermeasure method: Plate-type WIB (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.
