Abstract
The aim of this study was to relate the mechanical behaviour of saturated clays to their structural characteristics. Two clays were studied: a kaolinite and a bentonite. The evolution of the shape, the size, the concentration and the orientation of the elements which constitute the clay structure was examined by means of scanning and transmission electron microscopes. Particular care was taken to avoid as far as possible disturbing the micro-structure during observation. The results showed the existence of particle breakage and the creation of structural anisotropy during loading. We can conclude from this work that the mechanical behaviour to clayed materials is largely dependent on the changes which occur at the scale of the particles. Copyright © 2000 John Wiley & Sons Ltd.
粘土固有各向异性和诱导各向异性的微观结构分析
本研究的目的是将饱和粘土的力学行为与其结构特征联系起来。研究了两种粘土：高岭石和膨润土。用扫描和透射电子显微镜研究了构成粘土结构的元素的形状、大小、浓度和取向的演变。特别注意在观察过程中尽可能避免干扰微观结构。结果表明，在加载过程中存在颗粒破碎和结构各向异性的产生。从这项工作中我们可以得出结论，粘土材料的力学行为在很大程度上取决于颗粒尺度上发生的变化。版权所有©2000 John Wiley&；儿子有限公司。
