Rock mass quality and collapsibility evaluation method

The invention discloses a rock mass quality and collapsibility evaluation method. The method comprises the following steps: establishing a rock mass quality and collapsibility continuous evaluation system; establishing a continuity evaluation function of each evaluation index in the evaluation system; evaluating the rock mass to be analyzed and processing evaluation indexes; correcting the processed data to obtain rock mass quality and collapsibility evaluation scores; and completing a final rock mass quality and collapsibility evaluation result according to the score. According to the method, a new evaluation system with high practicability is established, and integration and summarization of evaluation index factors under an existing common method system are realized; subjective indexes are quantified by adopting a fitting function method to obtain a continuous nonlinear evaluation function of each factor index, so that the subjectivity of expert evaluation in a traditional method is greatly reduced, and th
