The invention relates to a process for manufacturing an ice zone bulbous bow reinforcing structure by sections. An angle steel combined horizontal tangent rib frame is adopted during bulbous bow sectioning, and a strong rib frame is used as a reference surface for lying manufacturing. The process for manufacturing by sections comprises the following steps: sectioning; putting a strong rib frame large assembly on a jig; putting a first layer platform large assembly on the jig and assembling; putting a second layer platform large assembly on the jig and assembling; putting a third layer platform large assembly on the jig and assembling: assembling a third layer platform plate and a third strong rib frame assembly into the third layer platform large assembly; putting a fourth layer platform large assembly on the jig and assembling; assembling a third middle longitudinal girder assembly and a fourth middle longitudinal girder assembly into a whole; mounting ribs; mounting an external plate. The process has the advantages that the angle steel combined horizontal tangent rib frame is adopted, and the strong rib frame is used as the reference surface for lying manufacturing, so that the production efficiency is improved, the period for constructing the bulbous bow by sections is shortened, and the shipbuilding speed is increased.
