[WIB Construction Method Case Study] Pre-construction Vibration Simulation for Pile Driving Work

The impact of vibrations on residential areas and commercial facilities was found to be almost nonexistent, except for a very small range!

During the construction of a temporary platform for the sluice gate work, a vibro hammer was used to install the pile bridge pier. The impact of vibrations on surrounding residential and commercial facilities was evaluated through simulation analysis using the two-dimensional finite element method (2DFEM). Based on these results, the client conducted explanations of the vibration impact to nearby residents and surrounding commercial facility owners before the construction began. Some vibration effects were observed in residential areas close to the vibration source at the start of the pile driving, but the overall impact on residential and commercial facilities was minimal, with only a very limited area affected. 【Case Overview】 ■ Client: A certain construction consultant ■ Analysis Period: January 2020 ■ Cost: 1.77 million yen (excluding consumption tax, analysis fee for five measurement lines) ■ Vibration Source: Pile driving vibrations from a vibro hammer ■ Analysis Content: Evaluation of vibration impact on residential areas around the sluice gate *For more details, please refer to the PDF document or feel free to contact us.
