摘　　要：粘土的应力诱导各向异性的发展,不仅仅是由过去所受的最大应力决定的,而主要取决于到达最大应力点的应力路径。通过试验分析了具有不同应力历史的正规压密粘土、异向压密粘土和过压密粘土的应力诱导各向异性的发展或消失方式以及对变形的影响。The development of inducing stress aeolotropism in clay which was not only decided by the maximum stress force, but also lied on the stress route of reaching the maximum stress point of clay. The development, disappearing means of inducing stress aeolotropism, and deforming characteristics induced by stress of different kinds of clays with different stress histories were analyzed in this paper.
