Development of an Oedometer Cell with Suction Measurement Ability

Abstract

To investigate unsaturated soil behavior during consolidation under K0 condition, a new undrained oedometer cell with matric suction measurement ability was developed based upon modifications on a conventional oedometer. A high-suction tensiometer was equipped to monitor matric suction variation during loading under undrained condition. Soil volume change during testing was recorded by a local displacement transducer. To validate the performance of this new oedometer cell, an undrained oedometer compression test was performed on an unsaturated soil specimen. Some preliminary results were obtained which included soil suction and volume variation during K0 loading. Test result indicated that the proposed system is very efficient and suitable to be utilized for unsaturated soil behaviors evaluation.
