Method of accurately producing arc geological section

Abstract

The invention discloses a method of accurately producing an arc geological section. The method includes the following steps: selecting a block name of a layer or a block object participating calculation, selecting a landform line layer, a geological boundary line layer and an intersected section layer on an intersected interface, ticking and checking whether projection exploration points exist, selecting block names of the projection exploration points, inputting a projection range, obtaining a section line with an arc segment on a CAD geological plane, and drawing a geological section map. The advantages of the method are that a main framework of the section map is drawn by calculating distances from nodes and crossed points to a starting point of a section line, geological contents are filled on the basis of the geological contents and exploration data on the map, and the geological section can be accurately produced for a construction building axis with an arc segment or a circle. The method is simple to operate, enables a map to be generated only by selecting layers participating calculation and setting information such as scales and pile pulling numbers, greatly improves the work efficiency, and does not need ornamenting in a later period.

Description

technical field [0001] The invention relates to a method for generating geological section diagrams in the field of engineering surveys in industries such as hydropower, water conservancy, highways, and railways, and in particular to a method for accurately generating arc geological section diagrams based on two-dimensional CAD engineering geological plane diagrams. Background technique [0002] Geological profile is one of the important manifestations of geological content, and its content and accuracy directly affect engineering design, and then affect engineering quality. At present, both CAD technology and GIS technology can automatically or semi-automatically generate geological profiles. Many papers and patents have published research reports on complex stratigraphic problems such as pinch-outs, faults, and missing strata. Under these conditions, the length of the drawn profile is not accurate, and the accuracy of the geological profile cannot be guaranteed. Contents...

At present, both CAD technology and GIS technology can automatically or semi-automatically generate geological profiles. Many papers and patents have published research reports on complex stratigraphic problems such as pinch-outs, faults, and missing strata. In this case, the length of the drawn profile is not accurate, and the accuracy of the geological profile cannot be guaranteed
