The aim of this research is to develop the image processing technique of micro-deformation mechanism by an ultra small shear box test (abbreviated as USSBT) apparatus, which was newly introduced into a scanning electron microscope (abbreviated as SEM) by the author. The mechanism of USSBT is similar with a direct shear test.The dynamic shear deformation of soils is very important to establish the constitutive equation of soils. The undisturbed diluvial clays, cement stabilized soft clays and incinerated ashes were used for USSBT, and their micro-shear deformation characteristics were observed by SEM. The macroscopic data of stress-strain were illustrated by a X-Y plotter and the microscopic data of particle behavior were stored in VTR. The dynamic movement of particles was analyzed from the recorded VTR film. It is focusing that the relation between the macroscopic deformation and microscopic particle movement was examined. This system of the image processing reveals its practical applicability.

本研究的目的是利用作者新引进的扫描电子显微镜中的超小剪切箱试验(USSBT)装置，发展微变形机理的图像处理技术。USSBT的作用机理类似于直剪试验，土的动态剪切变形是建立土的本构方程的重要依据。采用原状洪积粘土、水泥稳定软粘土和焚烧灰土进行USSBT试验，并用扫描电子显微镜观察其微观剪切变形特性。应力-应变宏观数据用X-Y绘图仪显示，颗粒行为的微观数据存储在录像机中。从录像带的记录中分析了颗粒的动态运动。重点考察了宏观变形与微观颗粒运动之间的关系。该图像处理系统具有较强的实用性。
