[WIB Construction Method Case Study] Railway Vibration Mitigation in Residential Development
Evaluate the vibration levels for each type of train! Confirmed an average reduction of 6dB in the horizontal direction and 5dB in the vertical direction!
Vibrations from trains passing near the residential development site in Kanagawa Prefecture (currently Fujisawa SST) raised concerns about their impact on the living environment after the construction of the houses. In response, the 'WIB method' was implemented directly beneath each house. Vibration measurements on the ground were conducted before and after the countermeasures. When evaluating the vibration levels for each type of train, an average reduction of 6 dB in the horizontal direction and 5 dB in the vertical direction was confirmed. [Case Overview] ■ Location: Kanagawa Prefecture ■ Client: Ando & Associates Co., Ltd. ■ Vibration Source: Railway vibrations ■ Preservation Target: Residential houses along the railway (total of 11 buildings) ■ Countermeasure Work: Plate-type WIB method (honeycomb cell type) ■ Construction Position: Directly beneath the receiving side *For more details, please refer to the PDF document or feel free to contact us.
