Recently, the landslide disaster is frequently occurred caused by frequently heavy rainfall. The before detection technology of the landslide is required to prevent the human live. In previous work, the internal soil state estimation technology based on soil-structure coupling was already proposed by an author. Above technique is composed from the elastic pile and electromagnetic exciter, in addition, the eigen mode of low frequency band under 250Hz lower was used. However, there is a problem about measurement resolution in the low frequency band. In this paper, consideration for expansion to high frequency band of proposed method was considered. First, the new vibration pile structure was proposed. In addition, the fundamental operation verification was considered in Laboratory bench set. Furthermore, operational modal analysis was performed in actual field.
