Abstract
This paper discusses a complex investigation to determine the microcrack closure and opening, with four different triaxial tests of a homogeneous isotropic limestone. Two of the researches
were under drained conditions (deviatoric triaxial test and triaxial test with constantly increasing stress) and two of them were under undrained conditions (triaxial test connected with decreasing confining pressure and triaxial test with constantly increasing stress). During the tests the uniaxial and the confining pressure, the pore-fluid pressure, and the axial and the lateral strains were
measured continuously
