Abstract: In order to explain the regularity between engineering properties of soil and geomaterial structure feature, the development process of image analysis method was explored in the research of geomaterial structure. Based on the principles, some characteristics of image processing technologies were analyzed on the macroscopic and microscopic structure of geomaterial. From the macroscopic structure, the mechanics properties of soil were quantitatively analyzed by the displacements of symbol mark embedded in the soil. From the microscopic aspect, the microstructure of soil was also quantitatively analyzed by the technology of scanning electron microscope. In addition, few researchers used the computerized tomography to study the soil microstructure. Finally, a new research method, that is, the combination between a long work distance telecentric microscope lens and charge coupled device(CCD), was proposed to discuss the microstructure of soil under static or dynamic loads.

Key words: geomaterial structure, image analysis, telecentric microscope lens, microscopic, mechanical property
