One-dimensional compression model of loess Q3 based on the disturbed state concept
According to the characteristics of loess such as soil macropore and overhead structure and water sensitivity, the confined compression test is designed and carried out under five kinds of different water content in order to reveal the influence of structure on the compression characteristics of loess Q3. Based on the disturbed state concept theory, and combined with the compression curves characteristics of intact loess and remolded loess, a disturbance function is defined with the void ratio as the parameters. At same time, the disturbed evolution law is analyzed. The results of the research show that: the disturbance function is accord with the exponential function, and the influence of water content on the parameter A of the disturbance function is accord with the exponential function too, and the influence of water content on the parameter B of the disturbance function is accord with the power function. A one-dimensional compression model of loess Q3 is constructed based on the disturbed state concept theory, which provides theoretical foundation for compression consolidation and calculation of the foundation settlement.
