Method for identifying and modeling wrinkle structure in map-cut geological section

The invention discloses a method for identifying and modeling wrinkle structure in a map-cut geological section, and the method specifically comprises the steps: (1) loading a map-cut geological section vector map layer, and reading stratum data; (2)re-encoding stratum codes based on the stratum code to generate character strings; (4) obtaining symmetrical repeated character strings, and filteringa repeated stratum; (5) constructing a wrinkle stratum set and a wrinkle stratum line set; (6) judging the wrinkle type based on the stratum line symmetrical distribution and the stratum new and oldrelationship; and (7) generating a smooth curve, and constructing a wrinkled ground surface. The invention realizes an automatic identification and modeling method of the wrinkle structure in the map-cut geological section. The wrinkle structure of the map-cut section can be efficiently identified, and the modeling quality of the map-cut geological section is improved. 本发明公开了图切地质剖面中褶皱构造的识别与建模方法，具体包括步骤：(1)加载图切地质剖面矢量图层，读取地层数
