摘要: 本文针对土的两个重要性质─—非线性和应力路径，建立了非线性弹性应力应变本构关系，并推导了等增量应力比条件下的切线模量表达式。通过试验验证，分析了模型的适用性。

Abstract: ln order to consider two important soil properties一nonlinearity and stress一path,a stress一strain consti-tutive relationship was developed in the paper,and a tangential modulus expression was deduced under the conditionof constant incremental stress ratio. The suitability of the model was analyzed and verified with laboratory data.
