Abstract
Soilbag can be used as a measure of absorbing and isolating vibration in geotechnical engineering. Researches related to field tests and applications can be found in literatures. The numerical simulation for evaluating the mechanism of soilbag, however, is not so popular because of some difficulties in modeling the ground and the material used as bags. This paper tried to evaluate and investigate the vibration damping effect of soilbag by numerical simulation and its applicability is verified by field tests. A dynamic finite element analysis based on an elastoplastic constitutive model named as subloading tij model (Nakai and Hinokio,2004) was conducted to simulate the field test, and it is found that the simulated results were in good agreement with the experimental results.
