| Outline of Final Research Achievements |
Monitoring technology of differential water pressure, motion of soil particle, etc. are required recently. In this research program, the following three kinds of prototype multi-wireless sensors were made and their performances were studied. 1) the multi-sensor composed of water pressure and 3-axis gyro which is used in the relatively slow ground motion such as long-term settlement and deformation, 2) the sensor composed of 3-axis accelerometer and gyro which records relatively long moving distance with relatively high velocity as a rigid body, 3) For laboratory vibration test, the sensor composed of 3-axis accelerometer, 3-axis gyro and pore water pressure meter which installed in the model ground. The data recorded in a memory is transferred by wireless contact after model vibration test.
