[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 the temporary scaffolding for the river gate's sluice work, a vibro hammer was used to install the pile bridge pier. The impact of vibrations on surrounding residential areas and commercial facilities was evaluated through simulation analysis using the two-dimensional finite element method (2DFEM). Based on these results, the client conducted explanations regarding the vibration impact to nearby residents and commercial facility owners before the construction began. Some vibration impacts were observed in residential areas close to the vibration source at the start of pile driving; however, the overall impact on residential and commercial facilities was minimal, with only a very limited range affected. 【Case Summary】 ■ 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.
