中文摘要：
基于多组排水条件下不同应力路径的平面应变压缩试验结果,结合等向加载—卸载的三轴试验数据,提出了上海粉细砂应力路径不相关的修正塑性功剪切—体积双硬化函数,并在此基础上构筑了上海粉细砂的双硬化弹塑性本构模型.数值计算与试验结果的比较表明,所提出的双硬化本构模型能比较合理地反映上海粉细砂的变形和强度特性.
英文摘要：
Based on the results from a series of drained plane strain compression（PSC） tests along different stress path and isotropic loading-unloading triaxial tests on Shanghai fine sand,the modified plastic work shear-volumetric double hardening function is proposed,which is independent of stress history and stress path.Then an elasto-plastic double-hardening constitutive model for Shanghai fine sand is formulated on the basis of the modified plastic work hardening function.The comparison between calculation results from the numerical method incorporating the proposed constitutive model and experimental data shows that the proposed constitutive model can reflect the deformation and strength behavior on Shanghai fine sand reasonably.
