Tunnel disease spatial correlation analysis method based on co-occurrence analysis

The invention provides a tunnel disease spatial correlation analysis method based on co-occurrence analysis, and the method comprises the steps: carrying out the ring-by-ring detection of a tunnel, and obtaining tunnel disease data information; acquiring a disease grade standard, and determining a disease grade based on the detected disease quantity value; determining a disease event for performing co-occurrence analysis according to the analysis target based on the disease level; constructing a disease co-occurrence matrix based on the disease events; constructing a disease adjacency matrix based on the disease co-occurrence matrix; calculating a disease co-occurrence rate based on the disease co-occurrence matrix; and drawing a tunnel disease co-occurrence network based on the disease adjacency matrix and the disease co-occurrence rate. According to the method, the co-occurrence window is designed, each grade of different diseases is independently used as a co-occurrence disease event, the spatial correlati
