| 摘 要： | 本文首次应用突变理论的尖点突变模型分析土的本构特性,建立了土相应的统一本构关系方程。该方程可以考虑软化土的应力路径,亦可分析硬化土的应力路径,统一本构方程通过试验检验是令人满意的。

| Abstract: | The cusp-eatastrophe model of catastrophc theory is first applied to analyse constitutive property of soil and its corresponding unified constitutive equations are proposed in this paper. These equations may be to consider not only stress-path of work-hardening soil but also stress-path of work-softening soil. The model is verified by comparing the predicted results with the measured results from laboratory tests. It may be seen that the cusp-catastrophe model for constitutional relationship of soil is promising to a great extent. |
