I. Overview

YUC.DMIZZ-1 low friction triaxial test instrument is mainly used for the strength test of deep foundation, heavy plant, large and medium water engineering, tailings stacking and foundation soil in geotechnical engineering, especially for supersolid soil or under anti-pressure saturation and condition. The instrument adopts high precision underwater sensor, which eliminates the influence of friction caused by the traditional external axial pressure sensor, and greatly improves the accuracy of axial pressure detection. The instrument can carry out a variety of total and effective stress triaxial tests, including: unconsolidated undrained shear (UU), consolidated undrained shear (CU), consolidated drainage shear (CD)
