Using of Piezoelectric Ceramic Sensor to Measure the Shear Wave Velocity of Bangkok Clay

Keeratikan Piriyakul, Narong Thumputi Thumputi



This paper presents the measurement of the shear wave velocity at the Soil Mechanics Laboratory of the Department
of Civil and Environmental Engineering Technology, College of Industrial Technology, King Mongkut’s University of
Technology North Bangkok. The research proposes a new technique to measure the shear wave velocity by using piezoelectric ceramic sensors. The details of this new technique and its interpretations on Bangkok clay material are clearly explained. The research found that this new technique is a reasonable technique, giving the shear wave velocity result in good agreement with the shear wave velocity data of the field test.
