| 摘 要： | 根据不同配比的EPS颗粒轻质混合土的等向压缩试验和固结排水剪切试验结果,研究了轻质混合土的变形特性。以殷宗泽所建立的双屈服面模型为基础,建立了考虑轻质混合土结构性的弹塑性本构模型。模型的试验验证结果表明,改进模型能反映不同配比EPS颗粒轻质混合土变形的基本规律。 |

| Abstract: | The deformation properties of lightweight EPS-bead-treatded soil were studied by isotropic compression test and consolidated drained triaxial test.By improving the two yield surface constitutive model of Yin Zong-ze,a new elastoplastic constitutive model considering the structure of the lightweight mixture specimen was put forward and verified with the test data. |
| Keywords: | Expanded Polystyrol(EPS) lightweight bead-treated soil elastoplastic constitutive model deformation properties |
