Primary Consolidation Theory of Saturated Soft Clay (Continuation): The Relationship between Clay's Water Content and Time during Primary Consolidation

The primary consolidation ration, utmost primary consolidation and the calculational methods of primary consolidation degree have been draw in the last paper (Study on the Theory Primary Consolidation of Saturated Soft Clay), they lie on the initial moisture and liquid limit, but they are independent of consolidate stress.Qua continuation, the connection of moisture and time during one dimensional consolidation has been searched.According to the one-dimensional-consolidated model and assumption, the second-order partial differential equations which moisture as the dependent variable has been established according to the one-dimensional-consolidated model and assumption.Through specific boundary conditions and initial conditions, using separation of variables and trigonometric functions orthogonal winner of the consolidation process of understanding the relationship between water content and style.The new formula of coefficient of primary consolidation and time factor has been obtained.They are similar in form with Terzaghi consolidation equation, but they are different in the substance, the former has searched change of the water content of soft clay, but the latter has searched change of excess pore water pressure.The new expressions of primary consolidation, the average degree of consolidation and remainder of primary consolidation have been drawn by the new one-dimensional primary consolidation equation.According to engineering data, it has been indicated that permeability coefficient, excess pore water pressure head, and the proportion of soft clay have not affected the new coefficient of primary consolidation Θ, except moisture.
