| Outline of Final Research Achievements |
Real-time acoustic measurement technique was developed for obtaining continuous air content of soils in drainage process. Water-saturated samples using Tottori dune sand was drained. I compared total air content obtained by drainage volume and mass of sample, and continuous air content obtained by acoustic method. It costs about 100 seconds to conduct a set of acoustic tests. Air content changed at a rate of 0.06～6 %/100 s in the first several minutes. Therefore, resolution time was sufficient except for first several tens of seconds. Measurement accuracy was about ±1 %. This was little different from the accuracy in the equilibrium state.
