Model：Small-Strain Hollow Cylinder Apparatus (GDSHCA) Country of Origin：UK
Use： Meets ASTM D-3999, ASTM D-5311, and ASTM D-6528 Standards. The GDS Small-Strain Hollow Cylinder Apparatus (SS-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. Two versions of the SS-HCA are available, a dynamic (SSHCA d) and a lower cost "static" (SS-HCA s) version.
The high density resistivity instrument High density electrical apparatus is a traditional method based on the theory of a new generation of electrical equipment in the development of computer and information monitoring based on modern scie
