石灰处置粉质粘土本构关系研究

Research on the Constitutive Relation of Silty Clay with Lime Treatment

通过粉质粘土和石灰处置粉质粘土的三轴试验,分析了粉质粘土及石灰处置粉质粘土破坏前的应力一应变关系,采用三次多项式拟合石灰处置粉质粘土的应力一应变试验曲线,建立了石灰处置粉质粘土破坏时的非线性模型,更好地反映粉质粘土及石灰处置土破坏时的应力与应变在工程中的应用价值.

By triaxial test of silty clay and lime treatment of silty clay. Analyzes the stress strain relationship of the silty clay and lime treatment of silty clay before destroying. Using cubic polynomial fitting stress strain curve that lime treatment of silty clay. Established the nonlinear model when the lime treatment of silty clay destroyed. Better reflect application value of stress and strain that the silty clay and limestone disposal soil is destroyed in the engineering.
