The invention discloses a tunnel surrounding rock quality uncertainty measurement method and device, and belongs to the technical field of tunnel surrounding rock quality measurement, and the method comprises the steps: building a tunnel surrounding rock quality uncertainty measurement index system; acquiring tunnel surrounding rock quality uncertainty data; performing coarse graining on the tunnel surrounding rock quality uncertainty data according to each preset state to obtain a sample data sequence of each index; respectively solving information entropy values of the index data sequences on the basis of the information entropy values; and on the basis of the information entropy values of the indexes, summarizing and summing to obtain a system entropy value for representing the overall uncertainty metric value of the tunnel surrounding rock quality. Through the method and the device provided by the embodiment of the invention, the uncertainty degree of the tunnel surrounding rock quality can be comprehensi
