Application:
The apparatus is designed and produced according to the standard of GB/T50123-1999. It is used to test resisting shear strength, deformation and pore pressure of the specimen under the iso-strain load and also can do UU, CU and CD test. Strain control is controlled by microprocessor to realize infinitely variable speed. Confining and back pressure are controlled by microprocessor automatically.
