Embodiment Construction

[0064] This embodiment provides a 3D stratigraphic modeling method based on overlay technology, such as figure 1 shown, including:

[0065] (1) Read the original borehole data in the modeling area into the original borehole data set, and add missing strata to the original boreholes in the original borehole data set according to the standard stratigraphic sequence table.

[0066] This step specifically includes:

[0067] (1-1) Read the original borehole data and corresponding borehole formation data in the modeling area, and store the data in the original borehole data set AD={ad i |i=1,2,...,m}, where, ad i Indicates the i-th original borehole, ad i ={lc i ,stglist i}, lc i for ad i information, stglist i for ad i The corresponding drilling strata list stores the serial number, top depth, bottom depth and stratum depth of each drilling stratum, and m is the number of original boreholes. Among them, the specific data structure and relationship of borehole information ...

Compared with the traditional method, the method of the present invention has higher precision in constructing the model.

Description

technical field [0001] The invention relates to the application field of geographic information technology, in particular to a three-dimensional stratum modeling method based on overlay technology. Background technique [0002] In recent years, with the support of GIS technology and computer technology, urban 3D stratigraphic modeling technology has made great progress, and a variety of 3D data models and modeling methods suitable for different engineering geological environments have been researched. The main data source for building a 3D stratigraphic model is engineering drilling data, but limited by the cost of engineering drilling, the available drilling data are often sparse and unevenly distributed. 3D models are not accurate enough. In response to this problem, Zhu Liangfeng et al. introduced the concept of virtual holes and applied them to the actual 3D modeling process, effectively solving the problem that limited drilling data cannot construct a relatively comple...
