Geological survey result expression method based on digital three-dimensional visualization

Abstract

The invention provides a geological survey result expression method based on digital three-dimensional visualization. The method comprises the following steps: 1, carrying out the arrangement of original data; 2, (1) geological data extraction; (2) discrete variable encryption; (3) data parameterization; (4) modeling a geological level; (5) geological entity modeling; 3, (1) performing oblique photography on the original earth surface; (2) carrying out three-dimensional live-action modeling on the original earth surface; 4, (1) performing preliminary fitting inspection on the model; (2) judging whether the two models are mutually fitted or not; 5, establishing a geologic body BIM model; 6, (1) drilling the BIM model; (2) building a pile foundation BIM model; (3) whether the drilling BIM model and the pile foundation BIM model meet requirements or not is judged; 7, binding model attributes; 8, a BIM sectioning model is established; 9, performing achievement arrangement; the expression method overcomes the defects that a traditional two-dimensional expression mode of the exploration design result is not visual enough, not accurate enough, scattered in information, inconvenient to inquire and difficult to clearly express the real condition of the underground geology.

Description

technical field [0001] The invention relates to the technical field of geological survey, in particular to a method for expressing geological survey results based on digital three-dimensional visualization. Background technique [0002] Geological survey is an indispensable key step in the process of engineering construction, and it is also the most important link in engineering construction. The accuracy and intuitiveness of survey and design results will directly affect the safety, quality, progress, and cost of engineering construction. Whether it is successfully realized. [0003] At present, the technical achievements of traditional survey and design mainly adopt the two-dimensional expression method combining CAD plan and section drawing, and use the soil distribution samples drilled at discrete exploration points to express the underground geological conditions. Traditional expressions are generally displayed in the form of drilling histograms, profiles and survey re...

Problems solved by technology

This method already has a relatively standardized operation form, and has rich engineering experience. It can describe the change of spatial geological structure to a certain extent, and has a high degree of specialization; but the intuitive effect is not obvious, and it cannot explain the law of spatial change, which is not conducive to geology. Numerical Analysis and Coordination with Other Specialties

[0004] The shortcomings of traditional survey and design technical solutions mainly include: 1. The expression method of traditional survey and design results is mainly two-dimensional plane, which is not intuitive enough, and it is difficult to clearly express the real situation of underground geology, making it difficult for decision-makers to intuitively Efficient design and decision-making; 2. The results of traditional survey and design only express the geological conditions of the exploration points, and these exploration points are discrete data, it is difficult to truly and effectively simulate the continuous change of underground space, which has brought great impact on the accuracy of design and decision-making. A lot of inconvenience will often cause improper foundation and foundation design, which will bring hidden dangers to safety, quality, progress, and cost for subsequent construction of the project; 3. The traditional survey and design results are expressed in scattered information and inconvenient to query. Usually, geological distribution, Important information such as soil quality information, geological properties, and mechanical properties are distributed on multiple drawings. When designers need to query this information, they often need to read a large number of drawings, and the query efficiency is very low.
