It is found that avery fast stress drop occurs at the beginning ofthe stages. Due to some regulation problem, the control system may cause a slight partial unloading at the start ofthe stage. The so resulted difference of the MRT compression curve and the standard compression curve is dependent on the soil texture. In case of 'large' partial unloading, locally negative effective stress can be caused in the sample in a stable way.
