Shaoxing University has successfully done an site acceptance for Dynamic Hollow Cylinder Apparatus



The GDS Hollow Cylinder Apparatus (HCA) allows for rotational displacement and torque to be applied to a hollow cylindrical specimen of soil. Using this device it is possible to control the magnitude and direction of the three principal stresses. Studies can for example be made of the following:

  • The anisotropy of soil samples.
  • The effects of principal stress rotation.
  • The effects of intermediate principal stress.
