[WIB Construction Method Case Study] Railway Vibration Countermeasures for Residential Areas Along Railways, January 2019, Saitama Prefecture
Measures were implemented directly beneath each residence from Building A to Building E! The vibration level has been reduced to below 60dB!
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 each of the residential buildings from Building A to Building E. Vibration measurements were conducted before and after the countermeasures. As a result, the dominant vibration at 10Hz was reduced by 14dB (to 1/5 of the original vibration), successfully keeping the vibration level below 60dB. [Case Overview] ■ Construction Location: Saitama Prefecture ■ Client: Housing Manufacturer ■ Vibration Source: Railway Vibration ■ Preservation Target: Residential buildings along the railway (total of 5 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.
