This paper deals with distribution of stresses in saturated with gas porous half-space about spherical inclusion. The case was examined when elastic characteristics of inclusion are the same with massif characteristics, but pressure inside inclusion is different from pressure in massif. Some results of numerical computation were given.

Science-based decision conception of rational method and modes of regeneration, strengthening and surface protection is proposed. This conception is based on considering of treating dynamic system element reliability. The scientific bases of necessary and sufficient adhesion value of deposition coating determination taking into account the service loads and their modes are developed.
