| 摘 要： | 为了揭示土体工程特性与其结构变化之间的内在规律性，探讨了图像分析方法在岩土结构研究中的发展历程，从基本原理上分析了各种图像处理技术在岩土的宏、细观结构研究中的特点。宏观上主要是利用跟踪技术，针对土体中标志点的移动来定量分析岩土的力学性能；微观上主要是利用电子扫描显微技术对土的微观结构进行定量分析，同时部分学者还发展了X射线计算机扫描技术。最后提出利用远距离、远心显微镜头和电荷耦合器件(CCD)共同作用，开辟了一种新的岩土动、静态微细结构研究方法。

| 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. |
