Map-cut geological section automatic generation method for loose bed coverage area

The invention discloses a loose bed coverage area-oriented map-cut geological profile automatic generation method, which comprises the steps of (1) loading a bedrock geological map, a regional geological map, profile line data, DEM data and drilling data, and extracting geological boundary information data; (2) collecting intersection points of the section line and all geological boundary lines; (3) generating a bedrock map section based on the bedrock geological map and the DEM; (4) extracting a loose bed section line set based on the regional geological map; (5) dividing the loose bed section line set into different groups based on the stratum continuous relationship; (6) collecting burial depth information of the adjacent drill holes; (7) generating an inference bottom line of each layer of the loose layer, and constructing a loose layer profile; and (8) combining and constructing a map-cut geological section covered by the loose bed based on the loose bed section and the bedrock map-cut section.
