| Morphologic Factors of Cohesive Soil Microstructures and Quantitative Information Processing Technique |
| As the authors'idea, morphologic factors of cohesive soils consist of Particle Shape, pattern, Porosity and Contact-way. Neither did these factors substitute for the structure features individualy, nor did the functions of them summing up simply reflect the engineering behaviors of soils. The morphologic system is complex, multi-administrative, dynamic and open, which characters could alter remarkably with its environmental condi-tion., But the structure state could be discribed in 11 structure parameters defined on ima-ge concept in paper, which behaved in an administrative relationship. With the Fractal the-ory, 7 non-linary structure factors of them were expressed quantitatively in corresponding factor dimensions, such as Particle Size Dim, Particle Distribution Dim, Particle Relief Dim, Pareicle Direction Dim, Porostity Dim, Pore Distribution Dim. and Contact-zone Distribu-tion Dimension, Respectively referring to the homogeneity of particles, particle distributing pattern, surface relief of grain, directive degree of particle, porosity, pore distributing pat-tern and relation between particles. In this way, the problem on mincrostructure quanfifica-tion have been solven in some extent. Anyway, all of these factors could be achieved with the Micro-structure Image Processing Systen (MIPS)developed by us . This equipment is chiefly composed of microscope, TV camera, image processor, PC computer and printer, which fundamental and working lfow are introduced in this paper. With the help of MIPS, we can obtain a lot of quantitative information about the microstructure of soils. |
