ActiveX-technology-based integrated drawing method for two-dimensional and three-dimensional profiles of engineering geology

Abstract

The invention relates to an ActiveX-technology-based integrated drawing method for two-dimensional and three-dimensional profiles of engineering geology. The method comprises the steps that: step one, a three-dimensional graph system is constructed based on OpenGL and is used for displaying a stratum and a drilled hole; step two, on the basis of the ActiveX technology, a profile coordinate in AutoCAD is guided into the three-dimensional system directly and stretching is carried out in a Z direction to obtain a three-dimensional profile, and the three-dimensional profile is drawn into the three-dimensional system; step three, a drilled hole three-dimensional model is constructed; step four, a stratum layer model is constructed; step five, profile and stratum interface intersection is carried out in the three-dimensional system; step six, projection of an intersected line segment after drilled hole and stratum interface intersection on a space plane is carried out; and step seven, on the basis of the ActiveX technology, the obtained intersected line and the line segment after drilled hole projection are outputted to the AutoCAD directly, thereby generating a two-dimensional profile. Therefore, the whole flow of engineering geology profile drawing, visualized geological profile calculation, and automatic graph paper drawing can be completed directly in a three-dimensional environment, thereby realizing informatization and automation of the geological profile drawing work.

Problems solved by technology

In the field of engineering geology, geological section drawing is one of the important daily tasks of geologists and engineers. The traditional two-dimensional section drawing method is complicated and cumbersome, and it is not easy to modify after making mistakes. The defects of heavy workload and low efficiency are becoming more and more prominent. Generally speaking, the traditional two-dimensional section drawing method has the following disadvantages:

[0004] (2) Heavy workload and low efficiency

In the traditional section drawing method, geometric projection, intersection and drawing are all done manually, which is primitive, inefficient and not accurate

Calculation results and design drawings are managed separately, and the scattered data is very inefficient in today's highly developed computer technology;

[0005] (3) It is cumbersome to modify the result drawings

Whether it is a change of the original model or a change of projection-related parameters, it will cause a corresponding change in all processes of section drawing. On the other hand, the modification requires heavy workload and low efficiency;

[0006] (3) Calculation results are not intuitive enough

The calculation process and results are limited to a single GIS or CAD system, that is, it cannot intuitively reflect the spatial position relationship of the integrated scene of the section above ground and underground, nor can it integrate the advantages of various software, and cannot achieve visualization, calculation, drawing, Full-process expression of achievement output

[0007] (4) The post-marking is cumbersome

The final result of the section design needs to output a variety of design drawings, and each drawing needs to add different annotation information. Manually adding these annotation information requires a lot of work.
