【摘要】：正5-2-1 00005 0059 STABILITY OP LAMINATED ROCK (THREE-DIWEHSIONAL LINEARIZED THEORY) A.N.GUZ (Institute of Mechanics, Kiev, Ukraine) In this report a systematic presentation is given of the foundations of three-dimensional linearised theory of equilibrium state stability in laminated rocks. Laminated rocks are considered, for modelling of properties of layers models of elastic and elastic-plastic body are used. In analysis the three-dimensional linearized theory of deformable bodies stability (for example,[1,3] is used. This theory is constructed by successive linearization of respective non-linear theories. Investigation were carried out within the framework of the continual approach and within the framework of the model of piecewise-homogeneous medium. A strict proof is given (for elastic and elastic-plastic bodies) of the applicability of the static method of analysis under the action of some loads. On this basis in the following analysis single classes of
