摘要建立了一般应力空间下k0固结软粘土的各向异性弹粘塑性本构模型。假设在任意加载应力下存在两个面作为加载面和参考面。通过一维应变条件下的粘塑性体积应变率建立标量乘法器。该模型能较好地模拟k0固结粘土不排水三轴恒应变速率剪切试验和不排水蠕变试验的应力-应变特性。在分析公式中研究了预固结压力和不排水抗剪强度的应变速率依赖关系,并分析了它们对应的应变速率参数的异同。
AbstractAn anisotropic elastic-viscoplastic constitutive model is developed for K0-consolidated soft clays in general stress space. Two surfaces are assumed to exist for any loading stress as the loading surface and the reference surface. The scalar multiplier is established by the viscoplastic volumetric strain rate under a one-dimensional straining condition. This model can adequately simulate the stress–strain behavior of undrained triaxial constant strain rate shear tests and undrained creep tests for K0-consolidated clays. The strain-rate dependencies of preconsolidation pressure and undrained shear strength are investigated in analytical formulations, and the similarities and differences of their corresponding strain-rate parameters are examined.
