内在地各向异性的土壤织物在土壤力量上有可观的影响。为这种固有的 anisotropy 建模，一个三维的各向异性的失败标准被建议，采用一个珍视数量的各向异性的变量和修改一般 threedimensional 各向同性的失败标准。在 deviatoric 飞机的所有部门的珍视数量的各向异性的变量被相关定义有规范的织物张肌的规范的压力张肌。在在 deviatoric 飞机的可得到的试验性的数据和相应模型预言之间的详细比较被进行。建议失败标准被显示很好在所有扇区预言失败行为，特别在有在 60 ° 和 120 ° 之间变化的矿脉角度的扇区 II，在预言几乎根据测试数据的地方。然而，建议标准在中间的主要压力比率 b 从约 0.2 ～ 0.8 变化了的部门 III 过高估计稠密的圣特蒙妮卡沙滩沙的力量，这也被观察，并且当 b 在约 0.8 和 1 之间时，稍微低估了力量。模型预言和试验性的数据之间的差别由于出现砍弯曲，它可能减少测量力量。因此，建议各向异性的失败标准有一个强壮的能力描绘各种各样的土壤的失败行为并且潜在地关于土壤织物允许对装载方向的影响的更好的描述。

英文摘要：

Inherently anisotropic soil fabric has a considerable influence on soil strength. To model this kind of inherent anisotropy, a three-dimensional anisotropic failure criterion was proposed, employing a scalar-valued anisotropic variable and a modified general three- dimensional isotropic failure criterion. The scalar-valued anisotropic variable in all sectors of the deviatoric plane was defined by correlating a normalized stress tensor with a normalized fabric tensor. Detailed comparison between the available experimental data and the corresponding model predictions in the deviatoric plane was conducted. The proposed failure criterion was shown to well predict the failure behavior in all sectors, especially in sector II with the Lode angle ranging between 60° and 120°, where the prediction was almost in accordance with test data. However, it was also observed that the proposed criterion overestimated the strength of dense Santa Monica Beach sand in sector III where the intermediate principal stress ratio b varied from approximately 0.2 to 0.8, and slightly underestimated the strength when b was between approximately 0.8 and 1. The difference between the model predictions and experimental data was due to the occurrence of shear bending, which might reduce the measured strength. Therefore, the proposed anisotropic failure criterion has a strong ability to characterize the failure behavior of various soils and potentially allows a better description of the influence of the loading direction with respect to the soil fabric.
