The invention provides a shallow water reverse barge riprap construction method based on ship stability calculation. The method comprises the steps of: preparation before construction; surveying and setting out; judgment of the water depth, and determination of a riprap scheme; before implementation of the riprap scheme, calculation of a maximum dip angle of a ship according to main parameters ofthe construction ship and an excavator, judgment of the ship stability, and judgment if the riprap scheme is feasible according to the maximum dip angle of the ship; implementation of the riprap scheme if the riprap scheme is feasible, anchorage and positioning of a positioning ship, and mooring of a riprap ship to the positioning ship; and completion of the riprap operation, the anchor heaving and the ship shifting. The method is easy to realize, and can calculate the maximum dip angle of the ship only by acquiring the common ship parameters and excavator parameters so as to judge the ship stability; and the scheme can be applied to the shallow water riprap construction method limited by specific conditions, and can provide relatively simple and practical ship safety checking foundation to the shallow water riprap construction method limited by the specific conditions, so that the smooth implementation of the construction scheme is guaranteed.
