摘要

摘要: 对目前国内外考虑主应力轴旋转的试验研究及本构模型研究进行了总结分析，并对进一步研究提出了相应的建议．基于不同的加载条件，从纯主应力轴旋转和耦合主应力轴旋转两个方面，较全面的描述了主应力轴旋转情况下土体的基本变形特性，并对考虑主应力轴旋转的土体变形试验提出了进一步研究的建议．较为系统地评述了当前较有代表性的考虑主应力轴旋转的土体本构模型（边界面模型、多机构模型、运动硬化模型和广义塑性模型），得出了广义塑性模型更适合用来描述考虑主应力轴旋转的土体变形特性的结论．总结未来考虑主应力轴旋转的土体本构关系研究的主要方向是：把握主应力轴旋转情况下土体变形的本质特性，建立推理严密、形式简单、适用方便的本构模型，并用来指导工程实践．

Abstract: The experiments and constitutive models considering principal stress axes rotation were analyzed, and the proposals for further study were offered. Based on different loading conditions, the basic deformation characteristics of soils considering principal stress axes rotation were described systematically and more suggestions were thrown out in terms of pure principal stress axes rotation and coupling principal stress axes rotation. The representative soil constitutive models (bounding surface model, multimechanism model, kinematic hardening rotation and generalized plasticity model) were commented systematically. It was concluding that the generalized plasticity model was more suitable for describing deformation characteristics of soils considering principal stress axes rotation. It shows that the major research directions of the soil constitutive relation considering principal stress axes rotation for further study are detecting the essential properties under principal stress axes rotation, building the reasoning strict, simply formed and applicable convenient model, and then guiding the engineering practice based on the achievements.
