1.      Main Function:

The apparayua is a kind of strain controlled direct shear apparatus used to test    resisting shear strength of soil specimen, it usually adopts four specimens under the different  vertical pressure exerted on the specimens to obtain shear stress when the specimen is destroyed. 
According to Colomb’ s law to confirm the resisting shear strength coefficient, 
  angle of internal friction and coagulable force of the soil.
