Conference paper


Pore-network model is a convenient tool to investigate the micromechanics of seepage in porous media. Geo-materials are typical porous media, including the different types of soils and rocks from rock-fill with mm-scale pores with high connectivity to gas shale with nm-scale pores and little connectivity. Based on the 2D image from CT or micro-CT technology, the 3D image of soil aggregates/rock matrix and pore structures for different types of geo-materials were obtained by the advance computational graphics technology. The pore size distribution and connectivity were derived from the developed 3D model, which agreed well with the experiment result. The seepage process was also simulated numerically via the developed micro-mechanics seepage model, and the pore-scale phenomena was revealed such as preferential flow. The hydraulic conductivities for various types of geo-materials from numerical simulation agreed well with the laboratory testing data, demonstrating the potential capability of pore-network model in hydraulic properties study for geo-materials.
