I. Overview

YUC.IZZYY12-1 fully automatic stress-strain control triaxial instrument, which is mainly used to measure the shear strength of undisturbed soil and artificially prepared soil, especially for the strength test of deep soil foundation, heavy plant, large and medium water engineering, traffic engineering and blowing fill and tailings, especially for supersolid soil or soil tests requiring anti-pressure saturation conditions. the maximum loading pressure of this instrument is 20 kn (optional for loading pressure). a variety of triaxial tests of total and effective stress can be carried out, including: unconsolidated undrained shear uuu, consolidated undrained shear cu, consolidated drainage shear cd and stress path test.

II. Performance characteristics:

• Built-in power, data visualization, real-time clock function
• Universal network data transfer interface
• Automatic computer control acquisition and processing, software has data upload function
• Support isotropic or non-isotropic consolidation
• The strain mode can do three-axis experiment of CU, UU and CD
• Pressure chamber automatic water injection, drainage
• High-precision hydraulic controller controls confining pressure backpressure
• The reverse pressure can be used to saturate and measure the displacement under reverse pressure
• Automatic mapping of stress-strain curves
• Real-time Display of Sensor Readings and Calculation Parameters
• Simple and fast setup and calibration
• Standard format test report output
• Data can be exported to Excel tables
• Standard 39.1mm triaxial pressure. Optional replaceable base and specimen cap, the same pressure chamber for 39.1mm ,61.8mm and other different diameter soil samples test.can also be customized in various sizes.
