- Abstract:
- An automated measurement system which aims to improving the method of "Bender Elements" for measurements of soil specimen characteristics is presented in this work. This is a well-known method for the estimation of the propagating velocity of shear waves in soil by measuring the travelling time of these waves. The system developed offers an automated acquisition and signal analysis tool which includes appropriate filtering of the incoming signal, automated identification of certain characteristics of the incoming waveform, automated measurement of the flight time of the signal, and calculation of other parameters in the soil specimen. Full range recording for all data and parameters of measurements, and measuring flexibility by using a wide set of initial parameters is also featured by this tool.
