摘    要:在水力-力学本构模型基础上,采用化学软化公式引入孔隙水中含盐、碱类等离子类溶质对土体前期固结压力的影响,得到土体的化学-水力-力学耦合本构模型(C-H-M 模型). 根据试验结果对化学软化公式的参数进行数值拟合,通过算例验证了C-H-M 本构模型的有效性

Abstract:Based on the theory of the soil hydro-mechanical coupling constitutive model, a chemical-hydromechanical coupling constitutive model (C-H-M model) of soil is proposed. In this model, the impact of salt and alkali ion solutes of the soil pore water on the preconsolidation pressure is considered by employing a chemical softening equation. A numerical simulation of the parameter in the softening equation is conducted on the basis of the experimental results. The C-H-M coupling constitutive model is validated by conducting a numerical simulation.
Keywords:chemo-hydro-mechanical constitutive model|ionic solute|computational simulation
