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。
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.
