Abstract

For soil improvement, the rigid bodies are cast into the soft ground at periodic distance. It is important to estimate macroscopic rigidity (S-wave velocity) of this improved ground for the construction of a building. Here we propose a new approach combining surface wave method and homogenization method in order to evaluate the vibration characteristics of improved soft ground. The homogenization method provides a microscopic equivalent homogeneous medium of improved soft ground. This medium is considered as a theoretical macroscopic model. As a result of simulation study, it is concluded that macroscopic S-wave velocity structure can be estimated from surface wave method by the restriction of the ratio between the wavelength of surface waves and the intervals of cast rigid bodies.
