The invention aims at overcoming the defects in the prior art and provides a control method for a turbine-based double-combustion-chamber punching combined cycle engine to solve the problem that relay of an existing turbine punching combined engine cannot be achieved under the low Mach number. By means of the control method, the double-combustion-chamber punching engine is improved firstly, and combustion chambers arranged in a rectangular parallel connection manner; an air inlet way of the engine is improved, the two-dimensional air inlet way configuration is adopted in the air inlet way, the air inlet way is divided into at least one subsonic combustion runner and at least two supersonic runners through supporting plates, wherein the supersonic runners are evenly arranged on the two sides of the subsonic combustion runner; and inner contraction section adjusting molded surfaces and expansion section adjusting molded surfaces are additionally arranged in the design of all the runners so that the size of the area of a throat of the air inlet way can be controlled, the requirement for air with different compression degrees of the combustion chambers is met, the Mach number range of work of the engine is enlarged, and the performance of the engine is improved.
