Description

TECHNICAL FIELD

[0001] The application belongs to the field of slope water content calculation, and particularly relates to a natural rainfall slope water content calculation and distribution visualization method. BACKGROUND

[0002] Rainfall infiltration is one of the main damage forms of landslide deformation and instability, and the change of internal water content of the slope is the main inducing factor of landslide. Because water is often concentrated near the sliding zone of the slope, the shear resistance of the sliding zone soil is reduced, and then the landslide disaster is caused. Therefore, the natural rainfall slope water content distribution visualization method will help to reveal the mechanism of rainfall landslide disaster.

[0003] Most of the rainfall infiltration researches of natural slopes rely on indoor experiments or numerical simulation, and cannot quickly, efficiently, non-destructively and continuously detect the water infiltration process of the slope. Because the internal structure of the rainfall type natural slope is complex and invisible, the rainfall water content migration of the slope cannot be directly described, which brings great challenges to the mechanism research of the rainfall type slope disaster and hinders the evaluation and early warning of the slope stability. Therefore, the natural rainfall slope water content distribution visualization has important significance for the understanding of the landslide mechanism.

[0004] However, most of the current researches on slope water content are based on laboratory models. For example, the patent with the publication number CN114878436A discloses a rainfall landslide visualization model based on transparent soil. The model disclosed in the patent includes a model body mixed by aggregates and pore fluid, a slope is arranged on the side surface of the model body, an upper seepage surface is arranged on the top of the model body, and a water-blocking adhesive layer is covered on the surface of the slope. The model has high transparency and good water permeability, and can simulate the seepage characteristics of rainwater. However, the model making cost of this method is high, and it can only simulate the rainwater seepage of fixed laboratory scale, and cannot be used for testing the natural slope.

[0005] For example, the patent with the publication number CN114810904A discloses a soil slope automatic monitoring and stability determination method. The soil water content measured on site is corrected with the water content obtained by indoor test to obtain the water content on site. The soil water content meter is used to measure the change of the water content of the slope soil, and the change of the soil water content of the slope in different time periods is measured and automatically uploaded. Although this method can measure the change of the water content of the natural slope soil on site, it can only measure the single point of the slope, the operation process is complicated, and the whole slope cannot be continuously measured, so it is difficult to objectively reflect the actual seepage condition of the natural slope.

The present application will be further described below in combination with the drawings and specific embodiments.

[0036] Embodiment 1: The present embodiment provides a natural rainfall side slope water content calculation and distribution visualization method, which mainly includes the following contents,

[0037] Step one, according to the slope size data information, the length of the slope measuring line is determined, the measuring points are determined on the slope surface at equal intervals according to the length of the measuring line, and the high-density electrical method electrodes are arranged at the measuring points respectively, all the electrodes are connected with the high-density electrical method instrument for measuring the slope rock mass resistivity; a rainfall device is arranged at the midpoint of the measuring line, and a observation well is constructed in the range of one third to two thirds of the measuring line, and the distributed water content sensors are installed in the observation well at intervals for measuring the water content of the measuring points at different depths in the observation well.

[0038] As shown in 图1 , the length of the slope 4 measuring line is 29.5m, an electrode 2 belonging to the high-density electrical method instrument 1 is arranged at an interval of 0.5m, and the number of electrodes is 60; a rainfall device is arranged at the midpoint of the measuring line, i.e. 14.75m, and the height of the rainfall device is higher than the slope 2m to ensure that the rainfall can cover the entire slope. The measurement area of the high-density electrical method instrument is in the form of an inverted trapezoid completely covering the slope, and the depth is the deepest at one third to two thirds of the measuring line, and the observation well constructed in this range can measure the water content of the deepest part of the slope. In this embodiment, an observation well is constructed at 13.25m of the measuring line, and the distributed water content sensors 8 are installed in the observation well at intervals of shallow density and deep sparsity, for example, the sensors can be arranged at intervals of 0.3m, 0.75m, 1.25m, 2m and 3m, and the water content measured by the distributed water content sensors is the water content of the slope medium.

[0039] Step two, use the total station to measure the height of each measuring point electrode of the high-density electrical method instrument arranged on the surface of the slope 4, and obtain the relative height of each measuring point electrode of the high-density electrical method instrument, as shown in Table 1 below, and use the res2dinv software to correct the height of the electrode (2).

[0058] Step 5: Extract the resistivity data of different depths corresponding to 0 hours, 2 hours, 4 hours, and 6 hours at the observation well location using the high-density electrical instrument. At the same time, extract the corresponding one-dimensional water content data set. Perform quantitative analysis on the corresponding resistivity data and water content data to establish a functional relationship between resistivity and water content:

[0059] w=qn*ln(ρ+k)

[0060] In the formula: w is the water content, p is the resistivity, q, n, k are constants.

[0061] This embodiment takes the 0 hour, 2 hours, 4 hours, 6 hours corresponding to 0.3m, 0.75m, 1.25m, 2m, 3m one-dimensional resistivity data set at 13.2m of the survey line (see Table 7), and extracts the corresponding one-dimensional water content data set, to quantitatively analyze the data of the resistivity data X axis and the water content Y, and establish the function relationship between the resistivity and the water content, w = 197-26*ln(p+569).

[0062] Step six, through the function relationship between the slope resistivity and the water content established in step five, the slope resistivity corresponding to the distance and depth information at different data collection times in step four is converted into the slope water content data corresponding to the distance and depth information at different data collection times,

[0063]

[0064] This embodiment converts the slope resistivity data in Tables 3-6 through the established relationship between the slope resistivity and the water content, and obtains the slope water content data corresponding to the distance and depth information at 0 hours, 2 hours, 4 hours, 6 hours, which is shown in Tables 8-11 as follows.
