Introduction The superiority of dynamic centrifugal model tests to soil dynamics and geotechnical earthquake engineering has become an international consensus [1-2], simultaneously large scale centrifugal shakers with the maximum shaking load≥1000kg have become an important index for technical level evaluation of a country’s geotechnical earthquake engineering testing.
Such situation severely limits the development of domestic geotechnical earthquake engineering [3].

Study on Microstructure of Soil using MATLAB YU Chuang WU Licai, CHEN Zhanglong, (College of Architecture and Civil Engineering, Wenzhou University, Zhejiang Wenzhou 325035,China) Keyword: soil; microstructure; Matlab; SEM image processing ABSTRACT: This paper analyzed the feasibility of study on microstructure of soil using Matlab, and based on the theoretical model , introduced the fundamental principles, method and detailed process of dealing with soil SEM picture by making use of Matlab.
INTRODUCTION The soil microstructure is an important factor that determines the engineering properties of soil.
For one thing, through the study on soil microstructure, we can qualitatively explain the origin of some engineering properties of soil and some special engineering mechanics phenomenon.
Matlab is a very famous engineering software that was introduced by American MathWork Company in 1984, its strong graphics capability has known by many people, it has been widely used in a large amount of fields and acquire great achievement.
