Abstract

Automated testing systems are presently widely used in soil laboratory strength testings to monitor load, displacement, and pressure. A new device is introduced here for automatic measurements of the volume change of soil specimens during drained triaxial tests. The device is versatile and capable of monitoring volumetric changes of soil specimens with various dimensions, volume change characteristics, and degrees of saturation. It can also be used to measure the pore pressure inside a soil specimen during an undrained test.

Keywords:
laboratory tests, soil tests, pore pressures, automatic measurements, pore pressure measurements, volume change measurements
