For the media with periodic changes in Young’s modulus and yield strength, the problems of stress, strain and displacement distribution around single excavations of spherical and cylindrical shape are solved. Block structure of the medium is determined by the difference between the elastic modules and the yield strength in the blocks and interblock space. In each case analytical solutions are obtained. The influence of blocks quantity, difference in block properties and interlayers on the nature of changes in stresses, strains and displacements was studied. It is noted that block structure is one of the factors for forming zonal disintegration around excavations.
