Propagation characteristics of elastic waves transmitted through sand soils under dry and saturated conditions

摘要

The propagation characteristics of elastic waves are one of the keys to understanding a medium. We focused on highly porous media under dry and saturated conditions, because elastic properties of highly porous subsurface ground are expected to change prior to landslide disaster due to rainfall. We modified our previous test to obtain more stable signals under both dry and saturated static conditions without water flow. In the results, we succeeded in obtaining stable signals under both dry and saturated conditions.
