Energy multi-scale method to analyze the scale effect of soil particles

As a common geological material, soil is key aspect of construction engineering. Soil has typical multi-scale characteristics, but current methods analyze these characteristics only in regard to geometric space. More exploration the coupling influence mechanism basic properties particles on microstructure and macroscopic needed. This study analyzed scale mineral composition surface energy at microscopic level for development method. Experiments were performed determine particle size plasticity index ( I p ) soil, experimental results are discussed interpreted quantitatively using The conclusions derived from this work as follows: 1) can cause interface effects; 2) comprehensive ratio micro-force weight (CRFW) be determined method reflects soil; 3) explains allowed identification new division plasticity. When CRFW was used control index, three materials practically same, even if sizes different.
