Abstract. The purpose of researches is the generalization of the most effective methods of different theories of strength for description of composition materials. As a result of analysis and generalization of mechanical theories of strength and their experimental approbation features and possibilities of their application for description of composition materials strength properties are set. It is shown, than range of properties of the materials chosen for the tests is wider, the more reliable verification turns out, conclusions about authenticity and applicability of those or other strength condition will be the more so sure. On this basis the variants of the anchor swiped support, which lower stratification of rocks, are developed, their compression by volume is provided, that, in the end, is warned by the origin of shearing deformations. The methods of the anchor supporting of rock massif, which foresee the preliminary change of properties of the supporting rocks are developed, that permit to create constructions more monolithic and steady from composition materials.

Keywords:

 composition materials, theories of strength, stress-deformed state, tensile strength, anchor support.
