Abstract
Plate type transducers were newly developed and installed in a triaxial apparatus. The performance of the plate type transducers were successfully conducted and compared with other types of dynamic measurement, such as bender element method and Trigger Accelerometer method, and static measurements. Overall, it was found that the plate transducers were less affected by the bedding error inevitably encountered with bedding errors and free from boundary conditions imposed upon trigger-accelerometer system. As such, it would be very useful to use plate transducers to conduct dynamic measurements precisely on soil samples if sample disturbance is to be avoided, especially in case of undisturbed soils. However, currently its use could only be limited to fine grained soils as the amplification level is not high enough to produce detectable output deformation for coarse grained soils.
