Railway tunnel extremely-high ground stress identification method based on aviation geophysical prospecting three-dimensional inversion result

The invention relates to a railway tunnel extremely-high ground stress identification method based on an aviation geophysical prospecting three-dimensional inversion result. Whether the railway tunnelhas extremely high ground stress or not is quickly identified by utilizing an aviation geophysical prospecting three-dimensional inversion result, and a basis is provided for railway line selection.The method comprises the following steps of: 1) performing MTZ3Dinv three-dimensional inversion on aviation ZTEM data of a plurality of measuring lines acquired above a railway tunnel after data preprocessing to form a resistivity three-dimensional result map, and extracting a tunnel longitudinal section and tunnel body tangent plane resistivity contour map according to the resistivity three-dimensional result map; 2) carrying out MVI three-dimensional inversion on TMI data obtained after preprocessing and normal field correction are carried out on the aviation magnetic survey data simultaneously carried and collected
