device for investigation of inner stresses in earth semi-space

摘要

Device for investigation of internal stresses in earth semi-space includes vertical hollow body made of two parts and indicator as tensiometric gauge of normal stresses. Parts of the body are rigidly fit to each other, on the outer surface along the lower of those in central long plane sockets are provided, axes of symmetry of those and the body are normal to each other. Indicators of stresses are placed in the sockets.
