DETAILED DESCRIPTION

[0023] In order to make the objects, technical solutions and advantages of the present application clearer, the following will clearly and completely describe the technical solutions in the present application with reference to the drawings in the present application. Obviously, the described embodiments are only some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall into the protection scope of the present application.

[0024] The measurement methods of the adsorbed water of the sediment in the related art include X-ray diffraction method, pressurized drainage method, centrifuge method, hygroscopic method, volumetric flask method, electrochemical method, ion exchange method, nuclear magnetic resonance method and thermogravimetric analysis method. Most of these methods are established on the basis of a monodisperse, rigid and spherical dilute dispersion system, and are inconvenient to apply in practice. Some of these methods are destructive to the sample, and the measurement results are inaccurate and time-consuming. Meanwhile, the adsorbed water measured by these methods is inconsistent, which is mainly because there is no uniform energy limit value for the division of the adsorbed water and the capillary water in engineering applications. The calculation of the content of the adsorbed water in the related art is generally based on the Debye length in the diffuse double-layer theory of argillaceous sediment. However, the Debye length as a characteristic decay length is not directly related to the interaction energy of the pore water, and the Debye length only depends on the liquid properties and is irrelevant to the surface properties such as charge and potential, so the calculation accuracy is low.

[0025] The following will be described in combination with Figures 1-3 The present application discloses a method for determining the content of adsorbed water of sediment clay.

[0026] As Figure 1 shown, the present embodiment proposes a first method for determining the content of adsorbed water of sediment clay, which can include the following steps: S101, according to the diffuse double-layer theory, a surface potential distribution expression of the sediment clay is constructed.

[0027] Specifically, based on the diffuse double-layer theory, it is assumed that the charged solid particles are placed in water. On the one hand, based on the entropy increase principle, the charged ions on the surface of the solid particles will leave the surface and diffuse into the water, and have a tendency to move away from the soil particles. On the other hand, the Coulomb force between the solid particles and the ions has a tendency to pull the charged ions back to the surface. These two effects form a diffuse double-layer on the surface of the charged solid particles. Based on the Poisson-Boltzmann equation, the surface potential distribution expression of the sediment clay can be constructed, that is, the relationship between the potential in the diffuse double-layer and the distance x from the surface.

[0047] Alternatively, step S105 includes: Set the value , the Boltzmann constant and temperature are multiplied to obtain a set total interaction energy ; According to the total interaction energy expression and the set total interaction energy , the corresponding target distance is determined as the surface adsorbed water thickness of the sediment clay particles; wherein the target distance is the distance between the sediment clay particles and the surface water molecules when the total interaction energy of the sediment clay particles and the surface water molecules is .

[0048] It should be noted that represents the intensity of the thermal motion of water molecules, and the mobility or disorder of water molecules in the soil depends on the relative size of the soil-water interaction energy and the molecular thermal motion. If the interaction energy is much higher than the molecular thermal motion, the interaction energy is sufficient to offset the effect of the molecular thermal motion to make the water molecule system tend to be random and ineffective. Assuming that the adsorbed water and the soil particle interaction potential energy is . Wherein can be set by the skilled person according to the actual situation, such as can be set to 0.5, which is not limited in the embodiment.
