AI Technical Summary

Problems solved by technology

2D and 3D integrated profile drawing of engineering geology requires frequent interaction of data in 3D systems and 2D AutoCAD. Using traditional methods, these files need to be converted into intermediate formats, and then processed after importing, the interactivity is too poor;

[0005] (2) The workload of drawing is heavy and the efficiency is low

In the traditional section drawing method, geometric projection, intersection and drawing are all done manually, the working method is relatively primitive, and is greatly affected by subjective factors

The calculation results are managed separately from the design drawings, the data are scattered, and the statistical work is inefficient;

[0006] (3) It is cumbersome to modify the result drawings

Whether it is the change of stratification data of rock and soil layer, or the screening statistics of relevant in-situ test and geotechnical test parameters, it will cause corresponding changes in all processes of profile drawing, resulting in relatively frequent repetitive work;

[0007] (4) Calculation results are not intuitive enough

In-situ test, geotechnical test data statistics, pile foundation, foundation pit parameter calculation process and results are limited in a single CAD system, that is, it cannot intuitively reflect the spatial variation of the section in each rock and soil layer, and the degree of visualization is low

[0008] (5) The post-marking is cumbersome

At present, 3D geological modeling technology is still mainly used in mining, energy and other technical fields, such as GOCAD, EarthVision, Geocom, etc., and there are few researches and applications in the field of geotechnical engineering investigation technology; and some modeling systems are huge and complex to operate , it is difficult for technical personnel to master; the constraints are too strict, and the editing workload is relatively large;

[0011] (2) Horizontal geological profile technology is not yet mature

The current 3D slicing technology is still dominated by vertical geological section technology, which can only describe the stratum distribution on a certain vertical plane, and cannot effectively reflect the overall distribution of rock and soil layers at different elevations or different target horizons. Provide comprehensive and effective technical support for survey, design, construction, etc.;

[0012] (3) Lack of 3D data modeling standards for geotechnical engineering surveys, poor sharing

In essence, it still simply connects the formation lines between two boreholes with a spline curve, and does not conduct a comprehensive analysis based on the relevant in-situ test, geotechnical test and other data that can be reasonably used;

[0013] (4) The simulation of 3D geological surface lacks timeliness and continuity

However, traditional databases do not include accurate geological attribute information

At the same time, since the boundary of the stratum is usually the boundary of the working area, not the natural boundary of the engineering stratum, the change of the 2D map will cause the 3D geological body to be updated, and it is difficult to ensure the timeliness and continuity of the 3D geological body results
