[0029] Embodiment 1:

[0030] This embodiment provides a method for calculating the landslide safety distance of a waste dump.

[0031] See also Figure 1 , the figure shows that the method includes step S10, step S20, step S30 and step S40.

[0032] Step S10. Acquire first data and second data of the target waste dump, wherein the first data is terrain-related data of the target waste dump, and the second data is property-related data of the waste body in the target waste dump;

[0033] Specifically, under normal circumstances, the waste dump is composed of multiple sub-slip surfaces, each of which represents a potential sliding surface in a specific area of ​​the waste dump. There may be certain interactions and associations between the sub-slip surfaces, which together form a complex landslide body. Therefore, the first data includes the relevant data of all the sub-slip surfaces that constitute the target waste dump, namely, the inclination, length and height of each sub-slip surface. The second data includes the mass of the waste body and the residual internal friction angle. Considering that when the waste body begins to slide on the landslide surface, the factors affecting the residual internal friction angle are very complex, and the residual internal friction angle will also drop significantly, the value of the residual internal friction angle should be different according to the different working conditions of the waste body. The original friction angle of the slag body gravel soil in the natural state is generally around 15 to 30°, and the corresponding residual internal friction angle is generally taken as one-fourth of the original internal friction angle. The value of the residual internal friction angle can be appropriately adjusted according to the actual situation, and there is no special restriction here.

[0034] Step S20. constructing a landslide body model based on the first data, wherein the landslide body model consists of a first sliding surface and a second sliding surface, and the sliding surface inclination angle of the first sliding surface is greater than the sliding surface inclination angle of the second sliding surface;

[0035] Specifically, considering that the waste dump is composed of multiple sub-slip surfaces, if the sliding equation of each sub-slip surface is established in sequence, there will be a problem of excessive calculation. Therefore, in the modeling process of this application, in order to simplify the analysis, it is considered that each waste dump contains only two main sliding surfaces, such as Figure 2 As shown in the figure, it is a landslide model. The AB segment in the figure is the first sliding surface, and the BC segment is the second sliding surface. These two sliding surfaces represent the main sliding surfaces of the landslide body of the waste dump, and can effectively reflect the overall stability and sliding characteristics of the landslide.

[0036] In order to ensure that the simplified landslide model can accurately reflect the sliding characteristics of the actual waste dump, it is necessary to distinguish the boundary position of the first sliding surface and the second sliding surface and the corresponding sliding surface inclination according to the inclination angles of the actual multiple sub-sliding surfaces.

[0037] Specifically, step S20 specifically includes step S21, step S22, step S23, step S24 and step S25:

[0038] Step S21. Calculate the inclination difference between any two sub-slide surfaces to obtain a plurality of first differences;

[0039] Step S22. Arrange the plurality of first difference values ​​in descending order, and select the difference value in the front row as the difference value to be selected;

[0040] Step S23. taking the two sub-slip surfaces corresponding to the selected difference values ​​as target sub-slip surfaces, and summing the inclination angle differences between the two target sub-slip surfaces and another adjacent sub-slip surface to obtain a plurality of second difference values;

[0041] Step S24. Determine the minimum difference from the multiple second differences, and use the target sub-sliding surface corresponding to the minimum difference as the segmented sliding surface;

[0042] Step S25. Based on the two segmented sliding surfaces, all the sub-sliding surfaces are divided into a first part and a second part, the first part is used as a first sliding surface, and the second part is used as a second sliding surface, to construct a landslide body model;

[0043] Specifically, by calculating the inclination difference of multiple adjacent sub-slide surfaces and gradually screening and optimizing them, the segmented slide surface can be effectively determined, and the multiple sub-slide surfaces can be divided into two parts to construct a simplified landslide model. This method arranges the inclination differences from large to small and gradually screens out the key differences. Combined with the comprehensive analysis of adjacent sub-slide surfaces, this method can ensure that the selected segmented slide surface can reasonably reflect the main sliding characteristics of the landslide body, improve the accuracy and efficiency of the model, and retain the key mechanical properties of the landslide body.

[0044] Specifically, step S25 specifically includes step S251, step S252, step S253 and step S254:

[0045] Step S251. Calculate the sum of the lengths and the sum of the heights of all sub-slide surfaces in the first part to obtain the total length and the total height;

[0046] Step S252. Calculate the ratio of the total height to the total length, and calculate the arcsine function of the ratio to obtain the sliding surface inclination angle of the first sliding surface;

[0047] Step S253. taking the inclination angle of the leftmost sub-sliding surface among all the sub-sliding surfaces in the second part as the sliding surface inclination angle of the second sliding surface;

[0048] Step S254. constructing a first sliding surface based on the sliding surface inclination angle, total length and total height of the first sliding surface, and constructing a second sliding surface based on the sliding surface inclination angle of the second sliding surface, to obtain a landslide body model;

[0049] Specifically, the total length and total height ratio of all sub-slip surfaces in the first part are calculated, and the inverse sine function is used to determine the sliding surface inclination of the first sliding surface. At the same time, the inclination of the leftmost sub-slip surface in the second part is used as the inclination of the second sliding surface, so as to construct the first sliding surface and the second sliding surface respectively, as shown in FIG. Figure 2 H, L and α in the formula correspond to the total height, total length and sliding surface inclination of the first sliding surface, respectively, and S and β correspond to the length and sliding surface inclination of the second sliding surface, respectively. This method simplifies the modeling based on the geometric characteristics of the sub-sliding surface, thereby effectively retaining the overall structural characteristics of the landslide body.

[0050] Step S30. Establishing a first energy conservation equation that complies with the law of conservation of energy in the process of the waste slag body sliding on the first sliding surface according to the second data, and establishing a second energy conservation equation that complies with the law of conservation of energy in the process of the waste slag body sliding on the second sliding surface according to the second data, wherein the sliding process of the waste slag body on the first sliding surface is an accelerated motion process, and the sliding process of the waste slag body on the second sliding surface is a decelerated motion process;

[0051] Specifically, in the landslide model, it is believed that when the slag body slides on the first sliding surface, i.e., the AB section, the gravitational potential energy of the slag body is converted into kinetic energy, thereby accelerating its movement; and when the slag body slides on the second sliding surface, i.e., the BC section, the gravitational potential energy is about to be exhausted, and the existence of friction causes the slag body to decelerate.

[0052] Specifically, step S30 specifically includes step S31, step S32 and step S33:

[0053] Step S31. construct a first energy dissipation calculation formula of the waste slag body based on the mass, the residual internal friction angle, the sliding surface inclination angle of the first sliding surface and the total length;

[0054] Step S32. constructing a first gravitational potential energy conversion calculation formula for the waste slag body based on the mass and the total height;

[0055] Step S33. Using the first energy dissipation calculation formula of the waste slag body and the first gravitational potential energy conversion calculation formula as the two ends of the equation, respectively, to obtain a first energy conservation equation;

[0056] Specifically, the first energy conservation equation is:

[0057]

[0058] Wherein, m is the mass of the spoil body; g is the acceleration of gravity; α is the inclination angle of the first sliding surface; is the residual internal friction angle; L is the total length of the first sliding surface.

[0059] Specifically, step S30 also includes step S34, step S35 and step S36:

[0060] Step S34. Constructing a second energy dissipation calculation formula for the waste slag body based on the mass, the residual internal friction angle, the sliding surface inclination angle of the second sliding surface and the preset sliding distance parameters;

[0061] Step S35. Based on the mass, the preset sliding distance parameter and the sliding surface inclination angle of the second sliding surface, construct a second gravitational potential energy conversion calculation formula for the waste slag body;

[0062] Step S36. Using the second energy dissipation calculation formula of the waste slag body and the second gravitational potential energy conversion calculation formula as the two ends of the equation, respectively, to obtain a second energy conservation equation;

[0063] Specifically, the sliding distance of the waste slag body on the BC section is calculated in this application.

[0064] The second energy conservation equation is:

[0065]

[0066] Wherein, m is the mass of the spoil body; g is the acceleration of gravity; β is the inclination angle of the second sliding surface; is the residual internal friction angle; S is the preset sliding distance parameter;

[0067] The preset sliding distance parameter is an unknown parameter, namely, a safety distance. In this application, it is necessary to construct a calculation formula corresponding to this parameter so as to solve it through known parameters.

[0068] Step S40. Based on the first energy conservation equation and the second energy conservation equation, calculate the safe distance of the target waste dump;

[0069] Specifically, the first energy conservation equation and the second energy conservation equation are combined to obtain the combined formula:

[0070]

[0071] Wherein, m is the mass of the spoil body; g is the acceleration of gravity; α is the inclination angle of the first sliding surface; is the residual internal friction angle; L is the total length of the first sliding surface; β is the sliding surface inclination angle of the second sliding surface; S is the preset sliding distance parameter.

[0072] because Substituting into the above combined formulas, we get:

[0073]

[0074] Wherein, m is the mass of the spoil body; g is the acceleration of gravity; α is the inclination angle of the first sliding surface; is the residual internal friction angle; β is the sliding surface inclination angle of the second sliding surface; S is the preset sliding distance parameter.

[0075] Simplifying the above formulas, we can get:

[0076]

[0077] Wherein, m is the mass of the spoil body; g is the acceleration of gravity; α is the inclination angle of the first sliding surface; is the residual internal friction angle; β is the sliding surface inclination angle of the second sliding surface; S is the preset sliding distance parameter.

[0078] Considering that the sliding surface inclination of the BC segment, i.e. the second sliding surface, corresponds to tanβ<0.3, it is considered that approaches 1, so the above formula can be simplified to:

[0079]

[0080] Wherein, m is the mass of the spoil body; g is the acceleration of gravity; α is the inclination angle of the first sliding surface; is the residual internal friction angle; β is the sliding surface inclination angle of the second sliding surface; S is the preset sliding distance parameter.

[0081] Therefore, the safe distance of the waste dump can be predicted by known parameter calculation, and corresponding prevention and control measures can be taken according to the calculation results to ensure the safety of the waste dump.

[0082] Step S50. Comparison operation: comparing the safety distance with the current actual distance to obtain a comparison result;

[0083] Step S60. Injection operation: when the comparison result indicates that the safety distance is greater than the current actual distance, a preset volume of solidified material is injected into the waste slag body to obtain a solidified target waste slag body;

[0084] Step S70: Estimation operation: estimating the residual internal friction angle of the target waste slag body, and recalculating the safety distance corresponding to the target waste slag body to obtain an updated safety distance;

[0085] Step S80: Repeat the comparison operation, injection operation and estimation operation until the safety distance is smaller than the current actual distance;

[0086] Specifically, by repeatedly comparing the safety distance with the actual distance and injecting solidifying materials according to the comparison results to adjust the internal structure of the slag body, the stability of the slag body is gradually improved; at the same time, the residual internal friction angle of the target slag body is estimated, and the safety distance is updated and calculated to ensure that the slag body achieves a higher stability after each adjustment until the safety requirements are met. By enhancing the stability of the slag body, its safety in the project is ensured.
