[0052] The correction method for pore size distribution curve of rock-soil material of the application will be described below. Figures 1-3

[0053] The embodiment of the application provides a correction method for pore size distribution curve of rock-soil material, which comprises the following steps:

[0054] Step S100, obtaining the actual porosity of the soil sample , obtaining the pore size distribution curve of the soil sample about pore size measured by the mercury intrusion method , and obtaining the measured porosity of the soil sample .

[0055] Specifically, first, a saturated soil sample is prepared, and the volume of the geometric body surrounded by the outer surface of the soil sample and the actual porosity of the soil sample are measured, and the porosity ​the volume of the pores of the soil sample to the volume of the geometric body surrounded by the outer surface of the soil sample the volume of the pores of the soil sample to the volume of the geometric body surrounded by the outer surface of the soil sample the volume of the pores of the soil sample to the volume of the geometric body surrounded by the outer surface of the soil sample the volume of the pores of the soil sample to the volume of the geometric body surrounded by the outer surface of the soil sample the volume of the pores of the soil sample to the volume of the geometric body surrounded by the outer surface of the soil sample the volume of the pores of the soil sample to the volume of the geometric body surrounded by the outer surface of the soil sample the volume of the pores of the soil sample to the volume of the geometric body surrounded by the outer surface of the soil sample

[0056] Step S200, based on the pore size distribution curve , a calculation formula of the porosity of the missed pores of the soil sample when the pore size is is established:

[0057] ,

[0058] wherein, is the minimum value of the pore size in the pore size distribution curve , that is, the abscissa corresponding to point A in , Figure 2 is a constant. , is the value of the pore size corresponding to the trough of the pore size distribution curve , that is, the abscissa corresponding to point B in , Figure 2 is a constant.

[0059] Specifically, after the pore size distribution curve of the soil sample is known, a calculation formula of the porosity of the missed pores of the soil sample when the pore size is is established:

[0060] .

[0061] For the soil sample, the smaller the internal pores, the more difficult it is to press the mercury in, and thus the greater the possibility of being missed. Therefore, the probability of missing the corresponding pore size can be described in a small pore size range by using the Gaussian distribution probability density.

[0062] Step S300, based on the porosity of the missed pores of the soil sample when the pore size is , the actual porosity of the soil sample and the measured porosity of the soil sample , a calculation formula of the actual porosity of the soil sample is established: ​​​​, and solve it using the following formula ,

[0064] Specifically, the actual porosity of the soil sample The measured porosity of soil samples was obtained by mercury intrusion injection. When known, This is the porosity of the soil sample that was missed. In the equation, only the constant is an unknown number, and the constant can be calculated by this formula Solve it, and finally, the aperture is The porosity of the pores that were missed in the soil sample Can also be calculated.

[0065] Step S400: Based on the porosity distribution curve and the aperture is The porosity of the pores that were missed in the soil sample , and obtain the corrected porosity distribution curve ,

[0066] .

[0067] Specifically, after executing steps S100 to S300, the aperture The porosity distribution curve Each pore size corresponds to a specific measured porosity value. The corresponding measured porosity value Plus the corresponding aperture The porosity of the corresponding missed pores , the corrected aperture can be obtained The corresponding corrected porosity value, that is, the analytical expression of the corrected porosity distribution curve can be .

[0068] Step S500: Based on the porosity distribution curve analytical formula Draw the corrected porosity distribution curve.

[0069] The method for correcting the porosity distribution curve of geomaterials provided by the present invention can quickly correct the porosity distribution curve measured by mercury intrusion porosimetry, thereby improving the accuracy of the porosity distribution.

[0072] Step S620, calculating the actual porosity of the soil sample by the following formula ,

[0073] .

[0074] Specifically, the volume of the soil material used in the preparation of the soil sample can be easily obtained, for example, the mass of the soil can be obtained by weighing, and the mass divided by the density of the soil material can obtain the volume of the soil material used in the preparation of the soil sample . The volume of the geometric body surrounded by the outer surface of the soil material minus the volume of the soil material used in the preparation of the soil sample is the volume of the pore in the soil sample, and the actual porosity of the soil sample can be obtained by the formula . .

[0075] In some embodiments of the present application, the measured porosity includes the following steps:

[0076] Step S710, obtaining the volume of the mercury pressed into the pore by the mercury intrusion method ;

[0077] Step S720, calculating the measured porosity of the soil sample by the following formula ,

[0078] .

[0079] Specifically, after the mercury intrusion into the pore by the mercury intrusion method is completed, the volume of the mercury pressed into the pore can be easily obtained, for example, the mercury can be transported by a fixed-diameter pipeline, and the flow rate of the mercury is measured to calculate the volume of the mercury pressed . The volume of the mercury is the measured volume of the pore, and the measured porosity of the soil sample can be obtained by the formula . .
