Liquid Measurement

To investigate the unsaturated soil properties, the measurement of volume change is dealt with both water and air volume changes. It cannot be defined by using only the volume of water flown in out from the specimen as saturated soil. This paper presents the volume change measurement by using image processing (IP) from the series of consolidated undrained (CU) and constant water content (CW) tests for saturated and unsaturated conditions of soil, respectively. The results, obtained between IP and the cell liquid measurement considered movement of piston and the cell expansion effect with pressure including creep, are good corresponding except the specimen has an irregular deformation.

Theoretical Accuracy

A triaxial cell has been modified to permit measurement of volumetric strains during deformation-rate-controlled and stress-controlled triaxial tests on frozen soils. In the system described here, a volume change in the soil sample alters the level of fluid in the triaxial cell. The fluid level can be monitored during the test using a sloping tube volumeter. Theoretical accuracy with this arrangement can exceed 0.1% of the sample volume.
