Theoretical Model And Analysis Method On Multicale Soil

The past several centuries have witnessed the great improvement in the study of soil. Ggeotechnical engineering has blossomed into a big discipline as well. However, compared to some other disciplines of engineering such as strutrual engineering and steel engineering, geotechnical engineering seems a little faulty. It is because that soil is much more nonuniform than steel, concrete, placstic etc. One major factor that leads to this nonuniformity is the scale of soil particle.In this paper, focused on the scale of soil, we have performed several major studies. 1. Study the method of performing multi-scale soil experiment. Use clay and sand to make the “Matrix-reinforced particle” model. 2. Perform some experimets on multicle soil, and found that the strength of soil will improve due to the rise of the number of particles and decrese due to the rise of the diameter of particles. 3. Make some particles with exact distribution and found that the statistical average diameters of these particles vary from the assumed uniform distribution particles. 4. Introduce the cell theory of multi-scale soil, and set up the relation between of scale-stress and tracditional stress. 5. Take the influence of scale into consideration and propose the new M-C formula and D-P formula.
