[WIB Construction Method Case Study] Traffic Vibration Mitigation for Newly Constructed Roads
Confirmed a reduction of more than 10dB, reducing vibrations to less than one-third! Measures were implemented directly beneath the road!
In Yamanashi Prefecture, with the establishment of new embankment roads, it became necessary to preserve the environment of residential areas along the route after the road opened. Therefore, the "WIB method" was implemented directly beneath the road. A running test using a backhoe was conducted before and after the measures (before road construction). As a result, a reduction of more than 10 dB in both horizontal and vertical directions was confirmed near the public-private boundary, and vibrations were reduced to less than one-third. 【Case Summary】 ■ Construction Location: Yamanashi Prefecture ■ Vibration Source: Road traffic vibrations ■ Preservation Target: Several residential buildings along the road ■ Countermeasure Work: Plate-type WIB (honeycomb cell type) ■ Construction Position: Directly beneath the vibration source *For more details, please refer to the PDF document or feel free to contact us.
