Tunnel surrounding rock identification method, system and equipment based on multi-model fusion and medium

The invention belongs to the related technical field of tunnel surrounding rock classification, and provides a tunnel surrounding rock identification method, system, equipment and medium based on multi-model fusion in order to solve the problem that existing surrounding rock classification identification is inaccurate, geological parameters and tunneling parameters are subjected to fitting processing, and a function model is obtained; the function model is used for guiding training of different identification sub-models, so that the identification accuracy is improved; carrying out fusion processing on output results of different identification sub-models by utilizing an improved D-S evidence theory; wherein the improved D-S evidence theory sets a corresponding weight for each evidence based on the evidence distance between the preliminary surrounding rock classification identification results of the identification sub-model; and a rolling window is set to dynamically adjust each evidence, so that the problem
