Three-dimensional refined expression method of irregular geological body

Abstract

The invention discloses an irregular geologic body three-dimensional elaboration expression method, which relates to the field of rock-soil and water conservancy and hydropower engineering, and solves the problem that an existing method is inaccurate to express an irregular geologic body. The irregular geologic body three-dimensional elaboration expression method adopts the technical scheme that the irregular geologic body three-dimensional elaboration expression method comprises the steps of through determination of irregular geologic body digitalization engineering geological parameters, on the basis of building correlation of an irregular geologic body geology attribute and the digitalization engineering geological parameters, in combination with practical exploration reveal for carrying out statistic analysis on distribution sites of an irregular geologic body, providing irregular geologic body digitalization engineering geological parameter range characteristic values, building a three-dimensional geology digitalization information model based on GOCAD (Geological Object Computer Aided Design) software, determining a three-dimensional space distribution pattern and a three-dimensional space distribution range of the irregular geologic body through correlation of the selected specific engineering geological parameter range characteristic values, and realizing irregular geologic body three-dimensional space elaboration expression. The irregular geologic body three-dimensional elaboration expression method provided by the invention can be beneficial for effectively improving geological exploration precision, and serves engineering designs.

Description

technical field [0001] The invention relates to the field of geotechnical and water conservancy and hydropower engineering, in particular to a three-dimensional refined expression method for irregular geological bodies. Background technique [0002] In nature, the rock (soil) body is subjected to internal and external geological forces, and some "irregular" geological bodies are formed that are difficult for geological engineers to accurately identify and express. In the process of survey and design, it is necessary to classify engineering geology according to the degree of geological action or different engineering geological characteristics, such as weathering unloading degree, engineering rock grade and water permeability. The regularity of the interface part of these classifications is poor, and the interface shape is "irregular". Difficult to express accurately and meticulously. [0003] The so-called irregular geological body refers to a geological body with the follo...
