Method and device for achieving numerical simulation of soil

Abstract

The present invention discloses a method and a device for achieving numerical simulation of soil. The method comprises the following steps: obtaining a two-dimensional scanned image of a soil sample;obtaining a three-dimensional image of the soil by carrying out three-dimensional reconstruction on the two-dimensional scanned image, and displaying a porous medium three-dimensional structure of thesoil through the three-dimensional image of the soil; obtaining the three-dimensional distribution of mineral composition in the porous medium three-dimensional structure of the soil, according to the radiation attenuation change indicated via a pixel point in the two-dimensional scanned image; and further adopting the Boltzmann grid method to accurately simulate the permeability coefficient andthe flow distribution of the pollutant NAPL, thereby obtaining a soil structure and achieving the description of the soil. Hereon, due to the two-dimensional scanned image of the soil sample and three-dimensional reconstruction therewith, the permeability coefficient and the flow distribution of the pollutant NAPL can be accurately simulated based on the obtained soil three-dimensional real structure, so that the soil can be described accurately and quickly. The method and the device for achieving numerical simulation of soil are easy to popularize and apply, and further assist in the soil remediation technology.

Description

technical field [0001] The invention relates to the field of computer application technology, in particular to a method and device for realizing numerical simulation of soil. Background technique [0002] Soil is one of the most basic and important natural resources of human society. With the continuous deepening of the industrialization process, soil pollution is becoming more and more serious, so that the pollution in the soil is receiving more and more attention. The research on removing the pollution in the soil, that is, the soil remediation technology is in the process of continuous improvement. [0003] In the exploration of soil remediation technology and the progress of soil remediation, the soil structure and the mechanism of the influence of soil structure on soil function are still unclear. Therefore, it is necessary to realize the data simulation of soil, and then obtain the original soil structure completely. And the corresponding quantitative information, whi...

Problems solved by technology

[0004] There are not many studies on soil structure, and the technology to realize soil structure simulation is often lacking in the acquisition of soil structure due to the difficulty of data measurement and the extraction deviation and loss in the process of data collation and processing. The limitations of accuracy and difficulty in generalization and application, let alone accurate and rapid description of soil
