... dangerous vertical tensile stresses. THE MODEL OF GRADUAL SHEAR FAILURE OF ROCKS Rocks contains many strucktural defects, holes and cracks. If stresses change through the distance much larger than the interval between structural defects, then such rocks may be regarded as a continuous medium. The main...

... criterion was also considered. The results of the numerical analyses show that the thermal load induces a clearly higher closure rate of the drift but only a minor additional load on the pillar. The development of the brittle zones around the drifts as a consequence of the tensile stresses are determinated...

.... From the initial loading to the maximum strength, the incremental loading method is mainly used. After the peak value, the incremental displacement method is successfully employed. For the tensile stress, the limited tensile strength is assumed. Therefore, the excess tensile stress is re-distributed...

... of slip, rotation, and punching to occur. These mechanisms readily induce tensile stresses and strains within the individual blocks which in turn are now more susceptible to tensile failure with the consequent effects of load redistribution and further progressive failure. The above features are examined...
