Research on Microstructure Statistical Model of Soil-Rock Mixture

Abstract:

Abstract: Soil-rock mixture is one of the complex geological bodies, in which microstructure is critical to determine its mechanical property. So it is of great significance to establish a statistical model on the basis of statistical recognition of microstructure of this media. Digital images taken on-site and Autocad is used here to conduct recognition of soil and rock. Rock is equivalent to random polygon in this paper. Taking approximate ellipse as reference, the statistical characteristics of long axis,short axis ,flattening and boundary roughness can be obtained. A stochastic model is established on this basis. Biaxial compression test curves are attained by digital image model and rock stochastic model confirm the effectiveness of statistical model of long structure in soil-rock mixture and the method of stochastic media generation.
