The invention discloses a shield segment type selection and prediction method, which comprises the following steps of: S1, determining an assembly rule of each ring segment according to the condition of a construction site; s2, dividing a tunnel design axis into a plurality of straight line segments and curve segments, and sequentially calculating linear parameters of each straight line segment and each curve segment according to the mileage size sequence; s3, linear parameters corresponding to the tunnel design axis position where the current shield tunneling machine is located are obtained; s4, calculating all optional splicing point positions Ki of the current ring duct piece; s5, carrying out weighted calculation on the axis rotation angle, the shield tail gap, the thrust cylinder stroke and the shield tunneling machine trend of the current ring pipe piece, calculating a weighted score Ji of each selectable splicing point position Ki in the current ring pipe piece, and selecting the splicing point positio
