“…Drawing on soil mechanics theory, Xie [4] proposed the concept of comprehensive structural potential, and developed constitutive models of loess. Many other scholars [5][6][7][8][9][10] studied the structure and constitutive models of loess by the disturbed state concept (DSC) theory [11][12][13][14][15][16][17][18][19][20][21].…”

Despite being insufficiently compacted, the loess structure can withstand a huge load like the super solid. This paper attempts to disclose how water content affects the bonding and arrangement of loess particles, and how it disturbs the loess structure. For this purpose, five confined compression tests are designed for intact loess and remolded loess of different water contents. Specifically, the disturbance function was defined with void ratio as the parameter based on the disturbed state concept (DSC) theory, considering how the structural features of loess Q3 affects the compressive strength. Next, the evolution law of the disturbance function was explored, and the influence law of water content on the parameters of the disturbance function was investigated. Finally, a DSC-based 1D compression model was constructed for loess Q3. The research results show that the water content has a great impact on the evolution law of the 1D disturbance function and its two parameters, and the influence can be described by exponential function. Besides, the experimental results show that our model can accurately describe how water content affects loess compression.
