An essential feature of stress-strain behavior of soils different from that of metals is the cross effect of the mean normal stress on the deviatoric strain and that of the deviatoric stress on the volumetric strain. In addition, it has been shown by experiment data, that the direction of plastic strain increment vector is not uniq uely defined by the stress state, but also dependent on the direction of stress increment vector during shear.

An essential feature of stress-strain behavior of soils different from that of metals is the cross effect of the mean normal stress on the deviatoric strain and that of the deviatoric stress on the volumetric strain. In addition, it has been shown by experiment data, that the direction of plastic strain increment vector is not uniq uely defined by the stress state, but also dependent on the direction of stress increment vector during shear. In order to better describe these mechanical properties of soils, a new concept of so-called partial yield loci is formulated. Oppositely, the yield locus in the usual mean is renamed as the general yield locus. According to this new concept, the yield of the volumetric yield locus introduces only the plastic volumetric strain; similarly, the yield of the deviatoric yield locus induces only the plastic distortional strain.The mechanical model based on this new theory satisfactorily explains the dependency of the direction of strian increment vector upon that of stress increment vector, and also explains the various behaviours of soils, such as dilatation-contraction and hardening-softening, as well. In addition.it has been shown, that the model is in accordance with I' iushin's postulate of plasticity and satisfies the requirement of uniqueness of solution in boundary value problems of elasto-plasticity.Finally,a special model for the normally consolidated clay is proposed.

土与金属材料不同的一个基本特性是平均压应力对偏应变以及偏应力对体应变之间的交叉影响。另外还有不少试验资料证明,土的塑性应变方向不是唯一的,而与加荷方向有关。为了考虑土的这些基本特性,文中提出了部分屈服面的新概念,并把传统意义上的屈服面称为整体屈服面。按照这一概念,体应变屈服面的屈服只引起塑性体应变,偏应变屈服面的屈服只引起塑性偏应变。基于这一概念建立起来的模式除了能反映塑性应变方向与加荷方向之间的依存关系外,还能说明土的剪胀—剪缩和硬化—软化现象,而且也符合依留辛的塑性假设和满足弹塑性边值问题的解的唯一性要求。文末针对正常压密粘土提出了一个具体的计算模式。
