The invention provides a method for determining the amount of a target material in a dam body, which comprises the following steps of: drilling and coring at a plurality of positions of the dam body along the cross section direction of the dam body to obtain the highest elevation, the lowest elevation and the target material purity of each layer of mixed material containing the target material in each core column in the dam body; according to the positions of the core columns and the highest elevation and the lowest elevation of each layer of the mixed materials in the core columns, fitting to obtain the highest elevation curved surface and the lowest elevation curved surface of each layer of the mixed materials, and according to the highest elevation curved surface and the lowest elevation curved surface of each layer of the mixed materials, performing integral calculation by combining a three-dimensional model of a dam body to obtain the volume of each layer of the mixed materials; obtaining the target mate
