This experiment was performed to invesitigate the rheological properties of rock under the high confining pressure.
The new apparatus made up three parts which was designed owing to develop the Bridgman's high pressure technique.
One of them, the pressure vessele could be withstood to 4, 000kg/cm2 of hydrostatic pressure. The other parts made up hydraulic press and its pressure generator. The total normal compression of press was 130ton on the hydraulic ram which contacted the specimen. The experiment carried out on each relations between stress strain, strength and confining pressure. The sample was selected from lime-stone. The effect of confining pressure was distinguished on the strength of lime-stone. The strength of lime-stone under the confined pressure up to 3, 000kg/cm2 was 4 times as large as it under the atmospheric condition. Moreover lime-stones showed the plastic deformation under the high pressure up to 1, 000kg/cm2 at stress-strain diagrams.
