Abstract
In the Kadoma area of the Second Keihan Road, the alluvium layer of ground is thick and the surface layer is extremely soft. For the construction on site, the authors carried out various countermeasure methods for vibration, specifically a construction method with minimal impact upon establishment of a manageable vibration level. A vibration impact inspection conference consisting of professors, experts, project owners and builders was also organized. This study reports on the countermeasure method for construction vibration on soft ground and the vibration level at a second construction site, and the effect of the countermeasure method on vibration, utilizing a continuous underground wall. In addition, regarding the effective evaluation of countermeasure methods on vibration for the benefit of local citizens, the results of the full implementation of countermeasure methods for vibrations indicated that communication with local residents is highly effective. An informative diagram of the vibration environment and a database of construction vibration results were created to explain the countermeasure process. The results indicated that it is important to effectively utilize both analog and digital information under the right circumstances.
