The Experimental Validation for Structural Constitutive Relationship of Loess with Wet Loading
In order to verify the rationality of the proposed structural constitutive relation of loess under wet load and the structural damage evolution law of loess under wetting and loading conditions,the structural mechanical properties of loess and the rationality of the structural constitutive relation of loess under wet load were verified by experimental research and numerical simulation.The results show that the structural constitutive relation of loess under wet load is in good agreement with the modified Cam-clay model in describing the mechanical properties of saturated remolded loess.The model can simulate the macroscopic mechanical response of remolded loess with different water contents.More importantly,the model has obvious advantages in simulating the mechanical properties of natural structural loess compared with Cam-clay model and modified Cam-clay model,and can accurately describe the macroscopic mechanical properties of natural structural loess tested.Through the comparative analysis of the measured results of the conventional triaxial test laboratory and the numerical simulation results of the model,the rationality and accuracy of the structural constitutive model of loess under wet load are verified.
