Abstract

The invention provides a method and a system for reconstruction and analysis of an earth-rock aggregate three-dimensional microstructure. The method includes preparing an earth-rock aggregate sample, subjecting the earth-rock aggregate sample to computed tomography (CT) scanning to acquire a CT cross-section image sequence of the earth-rock aggregate sample, acquiring rubble cross-section area of each CT cross-section image of the CT cross-sectional image sequence and dividing the rubble cross-section area into multiple independent rubble cross sections, registering the independent rubble cross sections in each CT cross-section image to generate a three-dimensional microstructure model of rubbles according to a registration result, analyzing the three-dimensional microstructure model to determine rock percentage, grain distribution, rubble spatial distribution, rubble geometrical features and rubble morphological characteristics of the earth-rock aggregate sample. The three-dimensional microstructure model is easy to generate by the method and the system. The method and the system have the advantage of accurate and reliable analysis result of the earth-rock aggregate and can be applied to numerical calculation and analysis directly.

Description

technical field [0001] The invention relates to the technical field of rock-soil medium analysis, in particular to a method and system for reconstructing and analyzing 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 boulders 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 s...
