The invention relates to the technical field of tunnel reconnaissance construction, in particular to a deep-buried long and large tunnel rockburst assessment visualization method based on a BIM model. The method comprises the following steps: establishing a BIM model with a three-dimensional geologic model of a tunnel site area and a tunnel model, performing crustal stress inversion on the BIM model to obtain three-dimensional crustal stress distribution of the tunnel site area, inputting the three-dimensional crustal stress distribution into the BIM model, dividing a high crustal stress area, and performing potential rockburst section division and rockburst grade evaluation on the BIM model according to a preset length segment. According to the method, a BIM model is divided into segments, primitive information of the BIM model in the segments is changed according to an evaluation result, visual expression is carried out, tunnel excavation numerical simulation is carried out on the BIM model, and a suggestio
