Method and system for solving number of reserved layers of flat layer construction supporting frame body based on stiffness method

The invention relates to the technical field of leveling construction, in particular to a method and system for solving the number of reserved layers of a leveling construction supporting frame body based on a rigidity method. The method comprises the following calculation and verification methods: assuming the number of reserved layers of a support frame body, determining a specific concrete strength design value according to the concrete period age, determining a specific concrete elastic modulus and a specific concrete rigidity value according to the concrete period age, determining a load distributed on each reserved layer according to the concrete rigidity, and calculating the concrete strength design value according to the load. Carrying out bearing capacity checking calculation according to the load distributed to each reserved layer and the actual strength of concrete of each reserved layer, rechecking whether the bearing capacity, deflection and crack of the floor meet the requirements or not, and if
