    COUPLING STUDY ON DAMAGE AND RHEOLOGICAL MODEL OF LOESS AND ITS PARAMETER

    • Based on experiment results,the creep propriety of Q3 loess with variation water content are analysed.As structural damage can decrease the strain modulus of loess,and the coupling action of creep laws of constitutive model of damage and rheology are also advanced.Being aware of the structural damage characteristic of loess,the rheological model of loess can reveal the natural deed of sudden destroy besides the advantage of less rheology parameter.In the paper,the pattern of model parameters changing with the water content of unsaturation loess are also studied as well as the methods that can decide the parameters of rheological model of loess are given by applying the rheology research results of structural soft soil.The result of numerical simulation shows that the constitutive model can describe loesss deformation characteristic well in the accelerated stage.
