Method and system for generating three-dimensional mesostructure of soil-rock mixture

Abstract

The invention proposes a method and system for generating a three-dimensional mesoscopic structure of a soil-rock mixture. The method includes: performing three-dimensional scanning on the block, and constructing a geometric model of the block according to the scanning result; According to the basic information of the 3D mesoscopic structural model of the soil-rock mixture generated as needed, the sample of the 3D rock is obtained from the database of the 3D model of the rock; The model type establishes the boundary model of the soil-rock mixture; according to the preset constraints on the placement of rocks, select blocks from the sample of rocks and put them into the boundary model of the soil-rock mixture to generate a 3D mesoscopic structure model of the soil-rock mixture; render, display and Output the 3D mesoscopic structure model of soil-rock mixture. According to the embodiment of the present invention, it is possible to conveniently realize the refined modeling and analysis of the three-dimensional mesoscopic structure of the soil-rock mixture.

Description

technical field [0001] The invention particularly relates to a method and system for generating a three-dimensional mesoscopic structure of an earth-rock mixture. Background technique [0002] Soil-rock mixture is a kind of complex rock-soil medium that widely exists in nature, and it is also a kind of geological body that is often encountered in geological engineering and geotechnical engineering. Due to the existence of super-diameter stones inside the soil-rock mixture, its physical and mechanical properties are difficult to obtain through traditional indoor or field tests. The research on the physical and mechanical properties of soil-rock mixtures has always been a difficult problem in the field of geotechnical engineering. [0003] With the development of numerical calculation technology, numerical experiments provide new technical support for the study of physical and mechanical properties of soil-rock mixtures. However, establishing a reasonable mesostructure model...

AI Technical Summary

Problems solved by technology

The three-dimensional mesoscopic structure model of the soil-rock mixture is constructed by randomly generating block-rock polyhedrons. Although the impact analysis of the block-rock on the physical and mechanical properties of the soil-rock mixture can be realized to a certain extent, it is difficult to reflect the real shape of the block-rock, thus affecting the reliability of the analysis results. sex
