[WIB Construction Method Case Study] Railway Vibration Mitigation for Residential Areas Along Railways, July 2014, Tokyo
Confirmed a reduction of 4 to 5 dB! A case where countermeasures were implemented directly beneath a house during its reconstruction!
In residential areas of Tokyo, vertical vibrations caused by passing trains were affecting the living environment. Therefore, during the reconstruction of the housing, the 'WIB method' was implemented directly beneath the residences. Vibration measurements on the ground were conducted before and after the countermeasures. As a result, a reduction of 4 to 5 dB in vibration was confirmed. 【Case Summary】 ■ Location: Tokyo ■ Client: Mitsui Home Co., Ltd. ■ Vibration Source: Railway vibrations ■ Preservation Target: Houses along the railway ■ 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.
