The paper considers the results of numerical simulation of the problem on the shock wave propagation in the non-uniformly heated medium: a flat shock wave interacts with a flat gas layer of reduced density, located at some distance away from a solid surface. A structure of an arising gas-dynamic flow is studied and its characteristic parameters are estimated. It is shown, that the existence of a gas interlayer with normal conditions between a solid surface and a heated gas layer substantially complicates the flow pattern - two triple points are formed, the rate of the altitude growth for the upper triple point and the relative rate of a portent "growing" out of the basic shock wave are reduced, vortex formations are formed and evolve.
