摘要粗粒料作为高土石坝的重要筑坝材料，其应力–应变规律受初始不等向固结和后续施工影响。考虑粗粒土各向异性特性的同时兼顾其剪胀性和初始不等向应力状态等主要性质，结合室内试验资料，运用应力变换方法和引入新的应力比参数等手段对经典双屈服面弹塑性模型的屈服轨迹和硬化轴进行修正。通过试验数据和预测结果的对比，表明修正的三维化各向异性双屈服面弹塑性模型能够较合理地反映粗粒土在初始不等向固结状态下的强度和变形特性。

Abstract：Coarse granular materials are the important construction materials of earth-rock dam. The stress and strain behaviors of coarse granular materials influenced typically by the initial stress states and following construction process. A revised double yield surface elastoplastical constitutive model is presented based on laboratory true triaxial testing. Stress transformation is applied；and a new stress ratio parameter is introduced to change yield locus and hardening axis，through which the anisotropy could be simulated. Comparison between the testing data and the model predictions shows that the revised anisotropic model reasonably describes the strength and deformation characteristics of the coarse grained soil under complex stress states.

Key words： building material coarse granular materials anisotropy double yield surface model
