Problems solved by technology

[0006] The technical problem to be solved by the present invention is that the traditional two-dimensional stratum grid editing is realized by topological structure. When traversing between two strata, some strata will inevitably be repeatedly retrieved, and the data storage is complicated. to provide a new type of two-dimensional stratum grid editing method and device for the stratum structure

Embodiment 1

[0055] like figure 1 As shown, a method for digitally editing a two-dimensional formation grid of a formation structure provided by an embodiment of the present invention may generally include the following steps S1 to S6.

[0056] Step S1, overall boundary drawing: the initial outline drawn by the user is used as the overall boundary of the two-dimensional stratigraphic grid, and the initial outline is a closed curve formed by sequentially connecting end to end of several line segments (it should be noted here that the embodiment of the present invention The curve in refers to a graph formed by connecting several points in sequence, that is, a graph formed by connecting several line segments end to end in sequence), the endpoints of the line segments are called nodes, and the initial contour is divided into auxiliary The formation line and the auxiliary formation line as the lower boundary, the two common nodes of the upper boundary and the lower boundary are called the first...

Abstract

The invention relates to the technical field of geological structure research. The two-dimensional stratum grid digital editing method of the stratum structure comprises steps of an initial contour drawn by a user serving as the overall boundary of a two-dimensional stratum grid; taking a part of auxiliary formation line drawn by a user in a minimum closed area and with two end points located on the boundary of the minimum closed area as a newly added part of a new auxiliary formation line; recording the use frequency of each node; and numbering the auxiliary stratum lines according to a certain sequence. The invention discloses a two-dimensional stratum grid digital editing device of a stratum structure. The two-dimensional stratum grid digital editing device comprises an overall boundarydrawing module, a newly-added auxiliary stratum line drawing module, a node recording module and an auxiliary stratum line recording module. Due to the fact that the stratigraphic structure can causesequential arrangement of the auxiliary stratigraphic lines to form a sequential relationship, retrieval and editing of the two-dimensional stratigraphic grids are very convenient, and the storage structure is simple.

Description

technical field [0001] The invention relates to the technical field of geological structure research, in particular to digital editing of two-dimensional formation grids. Background technique [0002] The geological structure of the stratum is the shape left over from the deformation or displacement of the rock stratum or rock mass due to the external stress in the process of geological formation. The geological structure is most prominent in the layered rock distribution area, and also exists in the igneous rock and metamorphic rock area, specifically manifested as rock folds, fractures, cleavages, and other planar and linear structures, such as figure 1 shown. The geological structure has a direct impact on the stability and leakage of building foundations. [0003] 2D stratigraphic grid editing is a combination of tools such as spatial information management, geological interpretation, spatial analysis and prediction, geostatistics, content analysis and graphic visualiz...
