Influence of Density on Mechanical Properties for Coarse-Grained Soil Based on Percolation Theory
2014
Coarse-grained soil is the main material of embankment dams, it is one of the major study objectives of soil mechanics. This paper introduces a method that utilizes percolation theory to explore the influence of soil density on mechanical property from the micro perspective. First it proposes the concept of stress network among particles; then it introduces the method of applying renormalization group theory for deducing; finally it derives the conclusion that in a uniform coarse-grained soil, the porosity and the mechanical property present a relationship of linear.
