The method comprises the steps that a construction area is divided based on preset conditions, and a reverse operation border area and a consequent operation center area are obtained; a floor unit is simplified into a rod piece unit, soil side pressure forms a uniform load to act on the rod piece unit, and the stress condition of the rod piece unit is obtained through analysis; establishing a two-dimensional model of a floor slab in a reverse operation border area, and applying soil side pressure to the periphery of the two-dimensional model to obtain analyzed unit stress and strain; establishing a three-dimensional model of the floor slab of the reverse operation border area to obtain overall structure performance information and corresponding component reinforcement information; a four-dimensional model considering the combined action of the soil and the main body structure is established, and construction simulation analysis of the whole process is carried out; and comparing the obtained analysis results, and adjusting the component reinforcement based on the comparison result. According to the method, the reinforcement scheme meeting the construction requirements can be obtained.
