Triaxial compressive tests on limestone are conducted with a variety of confining pressures that range from 2MPa to 10MPa. This observation causes us to conclude that the deformation of limestone can be divided into four stages and the wreck is brittle cutting
The peak and stub intensity value increase with the confining pressure adding up
but the strain of the stress peak has no relativity to the confining pressure. By the redressing analysis
the formula of relation between intensity parameters is produced.
