Outline of Final Research Achievements

We conducted a flume test and tried to grasp the changes in elastic wave propagation properties in the sediments before landslides. We firstly make a new apparatus to realize such experiments. Using the developed apparatus, the followings were found: 1) the speed of elastic waves changed very complicatedly in accordance with the ascend of ground water level, and 2) the speeds and the amplitudes of the elastic waves decrease a little before slope failures.
