SLB-1A Stress-Strain Controlled Shear Permeated Triaxial Test Apparatus

Application:
The apparatus is a type of multifunction flexible triaxial test apparatus which can conduct iso-stress and iso-strain control when triaxial test. It also can carry out unconsolidated-undrained test (UU), consolidated test (CU) and consolidated-drained (CD) test as well as some other tests such as anisotropic consolidation, isotropic consolidation, backpressure saturation, Ko test, stress path test and permeated test. Every unit of the apparatus is controlled by microprocessor and it not only can be operated independently, but can carry out data exchange with computer and data acquisition processing as well, The data exchange can be carried out by the computer with each other. The apparatus belongs to multi functions flexible controlled triaxial test apparatus.
