[0035] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0036] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0037] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a computer, a server, etc., or an electronic device, a virtual device, etc. that can realize the above functions. The following takes the safety risk level assessment device for soil slopes (hereinafter referred to as the assessment device) as an example to illustrate this embodiment and the following embodiments.

[0038] Based on this, the present application embodiment provides a method for assessing the safety risk level of a soil slope, referring to Figure 1 and Figure 2 , Figure 1 The flowchart provided in Example 1 of the method for assessing the safety risk level of soil slopes in this application is as follows: Figure 2 This is a schematic diagram of the overall process of one implementation of the method for assessing the safety risk level of soil slopes in this application.

[0039] In this embodiment, the soil slope safety risk level assessment method includes steps S10 to S40:

[0040] Step S10: determining whether there are instability fatal factors in the soil slope based on the slope characteristics of the soil slope.

[0041] It can be understood that a slope is a natural or artificial slope, which is composed of the top, surface, foot and a certain depth below the surface line, and has a certain height, slope and extension width. An earth slope refers to a slope composed of soil, sand and gravel or a mixture of soil and stone, and the entire slope is composed of soil.

[0042] It should be noted that the above-mentioned slope features may include image features, internal structure features, etc. The above-mentioned image features may be obtained based on remote sensing images, drone aerial images, thermal imaging, etc., which are not limited in the embodiments of the present application. By identifying the slope features, it is possible to determine whether there are unstable and fatal factors in the soil slope. The identification method may be a machine learning method or other methods, which are not limited in the embodiments of the present application.

[0043] It needs to be explained that, in order to evaluate the instability of the soil slope, the embodiment of the present application proposes an instability fatal factor, which may be a factor that plays a decisive role in the instability of the soil slope. Once this factor appears in the soil slope, the safety risk level increases.

[0044] In some implementations of the embodiments of the present application, the above-mentioned instability fatal factors may include: cracks at the rear edge of the slope, such as continuously extending open cracks at the rear edge of the slope (such as an opening greater than 0.5m); it may also include the deformation and displacement degree of the front edge of the slope, such as obvious soil swelling or displacement at the front edge of the slope; it may also include the degree of slope abnormality, such as abnormal misalignment and steep steps on the slope; it may also include longitudinal shear cracks on the slope surface, such as a large number of longitudinal shear cracks visible on the slope surface; it may also include the retaining wall condition of the slope protection project, such as the retaining wall in the protection project has obvious swelling, collapse or dislocation; it may also include the anti-sliding pile condition and anchor cable (rod) condition of the slope protection project, such as the anti-sliding pile has obvious swelling, tilt or bending, such as the anchor cable (rod) has broken steel bars (stranded wire) and the anchor head has obvious damage or detachment.

[0045] It should be noted that the instability fatality factor can be planned based on the soil slope conditions in actual applications, and the embodiments of the present application do not impose specific restrictions on it.

[0046] In practical applications, if any unstable fatal factor appears, the soil slope can be considered unstable, and the slope instability index SI of the corresponding soil slope can be set to a preset value (specifically, 1.0). That is, in step S20, when the unstable fatal factor exists, the preset value is used as the slope instability index of the soil slope.

[0047] Step S30, when the instability fatal factor does not exist, obtaining the slope characteristic index and the damage degree of the slope protection project of the soil slope;

[0048] Step S40: determining the slope instability index of the soil slope based on the comprehensive slope characteristic index of the soil slope and the damage degree of the slope protection project.

[0049] It should be noted that when there is no fatal instability factor in the soil slope, the slope instability index can be calculated based on the following formula:

[0050] SI = AP × UD;

[0051] Among them, SI is the slope instability index, AP is the comprehensive characteristic index of soil slope, and UD is the damage degree of soil slope protection project.

[0052] It should be noted that the above-mentioned soil slope comprehensive characteristic index is an index that can be used to describe and quantify various characteristics of soil slopes. These characteristics may include geometric characteristics, deformation characteristics, damage characteristics, surface water characteristics, etc., and the embodiments of the present application are not limited to this.

[0053] It is understandable that in some soil slopes, protective engineering measures may be built, namely soil slope protection engineering. Due to the influence of natural factors or human factors, the soil slope protection engineering will have a certain degree of damage, and the damage degree of the soil slope protection engineering can be a parameter used to describe its degree of damage.

[0054] Step S50, determining the slope hazard hazard index of the soil slope;

[0055] Step S60: determining the safety risk level of the soil slope based on the slope instability index and the slope disaster hazard index.

[0056] It should be noted that the above slope disaster hazard index can be an indicator for evaluating and quantifying the degree of damage or loss that may be caused by a disaster on a soil slope. By evaluating the safety level of soil slopes through the slope instability index and the slope disaster hazard index, the stability, danger and degree of danger of soil slopes can be comprehensively considered during the assessment process, thereby achieving a more accurate safety level classification.

[0057] In some implementations of the present application, the safety risk assessment of the soil slope can be calculated based on the following formula:

[0058] RS = SI × CS;

[0059] Among them, RS is the slope safety risk assessment score, SI is the slope instability index, and CS is the slope disaster hazard index.

[0060] In some implementations of the embodiments of the present application, the safety risk level of the soil slope can be divided based on the slope safety risk assessment score. Specifically, when RS≥0.3, it can be considered that the slope stability is poor, and the consequences of instability (i.e., loss of stability) are serious, and its safety risk level can be identified as red (i.e., extremely high risk). When 0.2≤RS<0.3, it can be considered that the slope stability is poor, but the consequences of instability are not serious; or there is a possibility of instability in the slope, and the consequences of instability are serious, and its safety risk level can be identified as orange (i.e., high risk). When 0.1≤β<0.2, it can be considered that there is a possibility of instability in the slope, but the consequences of instability are not serious; or the slope stability is good, but once the consequences of damage occur, the consequences are serious, and its safety risk level can be identified as yellow (i.e., medium risk). When RS<0.1, it can be considered that the slope stability is good, and the consequences of instability are small, and its safety risk level can be identified as blue (i.e., low risk).

[0061] The embodiment of the present application determines whether there is an unstable fatal factor in the soil slope based on the slope characteristics of the soil slope; when there is an unstable fatal factor, a preset value is used as the slope instability index of the soil slope; when there is no unstable fatal factor, the slope characteristic index and the damage degree of the slope protection project of the soil slope are obtained; the slope instability index of the soil slope is determined based on the slope comprehensive characteristic index of the soil slope and the damage degree of the slope protection project; the slope disaster hazard index of the soil slope is determined; the safety risk level of the soil slope is determined based on the slope instability index and the slope disaster hazard index. Since the slope instability index and the slope hazard index of the soil slope are determined, a comprehensive assessment of the soil slope is achieved, and the accuracy of the safety level risk assessment is improved.

[0062] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. Figure 3 and Figure 4 In the embodiments of the present application, Figure 3 The flowchart provided in Example 2 of the method for assessing the safety risk level of soil slopes in this application is as follows: Figure 4 A schematic diagram of the overall process of slope protection engineering damage evaluation provided in one implementation of the soil slope safety risk level assessment method of the present application; the steps of obtaining the slope comprehensive characteristic index and slope protection engineering damage of the soil slope include:

[0063] Step S31, determining the cross-sectional geometric characteristics of the soil slope;

[0064] Step S32, determining the slope deformation and failure characteristics of the soil slope based on the slope deformation degree of the soil slope;

[0065] Step S33, obtaining the slope failure history, surface water activity characteristics and site characteristics of the soil slope;

[0066] Step S34, determining a slope comprehensive characteristic index of the soil slope based on the cross-section geometric characteristics, the slope deformation and failure characteristics, the slope failure history, the surface water activity characteristics and the site characteristics;

[0067] Step S35, obtaining the damage degree of the slope protection project of the soil slope.

[0068] In some implementations of the present application, the method for calculating the slope comprehensive characteristic index AP may be as follows:

[0069]

[0070] Among them, A is the characteristic score of the cross-section geometry, B1 is the characteristic score of the slope deformation and failure characteristics, B2 is the characteristic score of the slope failure history, C1 is the characteristic score of the surface water activity characteristics, and C2 is the characteristic score of the site characteristics.

[0071] It should be noted that the cross-sectional geometric features may be features of geometric properties such as the shape, size, and relative positions of various parts of the soil slope on a certain section. The cross-sectional geometric features may be obtained based on remote sensing technology or through on-site surveys, etc., and the embodiments of the present application are not limited thereto.

[0072] In some implementations of the embodiments of the present application, the above-mentioned cross-sectional geometric features can comprehensively consider the influence of various indicators such as slope overload, slope top angle, soil density and shear outlet position. Based on the cross-sectional geometric features of the soil slope, the characteristic score of the cross-sectional geometric features can be determined. The method for obtaining the characteristic score of the cross-sectional geometric features can be based on a machine learning method or other methods, and the embodiments of the present application are not limited to this.

[0073] In some implementations of the embodiments of the present application, the characteristic score A of the cross-sectional geometric features of the slope can be obtained by using the following characteristic score query table of the cross-sectional geometric features of the slope:

[0074]

[0075] The cross-sectional geometry of the slope can be determined by technicians through on-site measurement and investigation. e =H0(1+0.35tanβ)+s / γ, where γ can be 16-20kN / m 3, is the overload of the top of the slope. The effective height of the slope takes into account the influence of the top angle (β) and the influence of the load (s). If the shear outlet of the landslide is exposed at the lowest point of the soil slope, then H0 = H s +H cw , where H s is the vertical height of the soil slope, H cw is the height of the retaining wall at the top of the slope; if the shear outlet is located in the bedrock area, the H0 calculation should include the height of this part of the bedrock. In some implementations of the present application, the slope cross-section geometry classification is related to the effective height of the slope and the average slope of the slope. For details, please refer to Figure 5 , Figure 5 This is a schematic diagram of the geometric cross-sectional characteristics of a soil slope provided in one implementation of the soil slope safety risk level assessment method of this application, wherein the horizontal axis of the coordinate is used to represent the average slope θ in degrees (°), and the vertical axis of the coordinate is used to represent the effective height H of the slope e , the unit is meter (m).

[0076] In some implementations of the present application, the slope deformation and damage characteristics can be determined by cracks on the slope, abnormal steps inside the slope, steep steps or bare walls at the rear edge of the slope, bulging at the front edge of the slope, local collapse of the slope, gully characteristics on the slope surface, etc. The characteristic score B1 of the slope deformation and damage characteristics can be obtained from the following slope deformation and damage characteristics query table:

[0077]

[0078] In some implementations of the present application, the slope failure history of the excavated slope can be determined based on the analysis of historical data and the results of slope investigation. The slope failure history can specifically include: confirmed landslides: landslides that can be confirmed by relevant document records; possible landslides: landslides that are not documented but are inferred based on geological surveys or exploration methods; severe landslides: landslides with a volume of ≥50m 3 ; or landslide volume ≥ 25m 3 And the landslide range is located above the top of the slope; Minor landslide: Minor landslide is defined as landslide that does not meet the conditions of severe landslide. The characteristic score B2 of the slope damage history can be obtained by referring to the following slope damage history characteristic score query table:

[0079]

[0080] In some implementations of the present application, the hydrological conditions of the soil slope may also be considered for the slope instability index of the slope. The present application embodiment uses the surface water activity characteristics as an example to illustrate the method of the present application. Specifically, the characteristic score C1 corresponding to the surface water activity characteristics can be scored by comprehensively considering the development of the slope vegetation and the surface water activity state, and can be determined by referring to the characteristic score query table of the surface water activity characteristics shown below:

[0081]

[0082] In some implementations of the embodiments of the present application, for the instability index of the slope, reference may also be made to the site feature C2 of the slope, which may comprehensively consider the adverse hydrological phenomena and adverse geological conditions in the slope, and may be specifically determined by referring to the feature score query table of the site feature shown below:

[0083]

[0084]

[0085] It should be noted that protective engineering measures may be built on some soil slopes, and the slope protection engineering damage degree can be used as a parameter to evaluate the degree of damage of the protective engineering measures. For soil slopes without protective engineering measures, the slope protection engineering damage degree can be used. For soil slopes with protective engineering measures, the step of obtaining the slope protection engineering damage degree of the soil slope includes: obtaining the engineering construction time of the soil slope; determining the time factor based on the engineering construction time; determining the slope protection types included in the slope protection engineering of the soil slope, and ranking the importance based on the slope protection types to obtain the ranking result; assigning a weight coefficient to each of the slope protection types according to the ranking result; determining the weight of the slope protection type according to the weight coefficient and type damage index of the slope protection type; determining the slope protection engineering damage index according to the weight of each of the slope protection types; and determining the slope protection engineering damage degree of the soil slope based on the time factor and the slope protection engineering damage index.

[0086] Specifically, the step of determining the damage degree of the slope protection project of the soil slope based on the time factor and the slope protection project damage index includes: determining the initial slope protection project damage degree of the soil slope based on the time factor and the slope protection project damage index; if the initial slope protection project damage degree is lower than a preset threshold, using the initial slope protection project damage degree as the slope protection project damage degree of the soil slope; if the initial slope protection project damage degree is not lower than the preset threshold, determining the slope protection project damage degree of the soil slope based on the index interval of the slope comprehensive characteristic index. The specific calculation formula can be as follows:

[0087]

[0088] Among them, UD is the damage degree of the slope protection project, and its value is obtained by normalizing the damage index of the slope protection project (the total score of the damage index is 100); US is the damage index of the slope protection project, and its value is obtained by summing the product of the sub-item evaluation scores of each protection project support effectiveness and the weight of each sub-project; K is the time factor, considering the construction history of the slope protection project, and dividing it according to the construction years of the protection project. If the specific time of the project construction cannot be obtained, the value of K can be taken as 1.4.

[0089] In some implementations of the embodiments of the present application, the value of the time factor can be determined by referring to the following time factor value table:

[0090]

[0091]

[0092] In some implementations of the embodiments of the present application, in order to determine the slope protection project damage index US, it is possible to first determine which slope protection types are included in the slope protection project of the earth slope, and rank the importance of these slope protection types. Based on the index system method, weight coefficients are assigned to each ranked slope protection type, thereby comprehensively considering the impact of damage to the protection project on the function and the degree of damage to the protection project, thereby improving the accuracy of the evaluation.

[0093] In some implementations of the embodiments of the present application, the importance of the protection projects can be ranked according to the type of slope protection project, and the weight coefficients of various types of protection projects can be determined by the index system method. By comprehensively considering the impact of the damage of the protection project on the function and the damage degree of the slope protection project, the damage index of each sub-item of the protection project can be evaluated, and finally the damage index and damage degree of the protection project can be determined.

[0094] In some implementations of the present application, the slope protection types can be divided into three categories: interception (drainage) measures (X1), slope protection facilities (X2), and support and anchoring facilities (X3). Considering the importance of rainfall to slope stability, the interception (drainage) measures (X1) are subdivided into three sub-items: interception (drainage) ditches (X2). 11 ), underground water interception (drainage) measures (x 12 )、Upward-inclined drainage pipe(x 13 ).

[0095] In some implementations of the embodiments of the present application, the types of slope protection projects may include the following four combinations: 1. Water interception (drainage) measures; 2. Water interception (drainage) measures + slope protection measures; 3. Water interception (drainage) measures + support and anchoring facilities; 4. Water interception (drainage) measures + support and anchoring facilities + slope protection measures.

[0096] In some implementations of the embodiments of the present application, if there are no support and anchoring facilities on the slope, that is, only interception (drainage) measures and slope protection measures appear in the project, the importance of the protection project is ranked as follows: interception (drainage) measures (X1) > slope protection measures (X2). If only support and anchoring facilities and interception (drainage) measures appear in the slope, the importance of the protection project is ranked as follows: support and anchoring facilities (X3) > interception (drainage) measures (X1). If all three types of protection engineering measures appear in the slope, the importance is ranked as follows: support and anchoring facilities (X3) > interception (drainage) measures (X1) > slope protection measures (X2). The damage index of the slope protection measures (X2) and support and anchoring (X3) can be determined according to the slope protection project damage index sub-item evaluation score table, and the weights γ1, γ2, and γ3 of each sub-item are determined according to the indicator weight coefficient value table, and finally the value of the protection project damage index US is determined according to the slope protection project comprehensive evaluation table.

[0097]

[0098]

[0099]

[0100]

[0101] In some implementations of the present application, if one or more water interception (drainage) measures appear in the soil slope, it is necessary to rank the sub-items of the water interception (drainage) measures, and the order of importance is: water interception (drainage) ditch (x 11 )>Underground water interception (drainage) measures (x 12 )>Upward inclined drainage pipe(x 13 ).

[0102] In the embodiment of the present application, the slope interception (drainage) measures (X1): include interception (drainage) ditches (x 11 ), underground water interception (drainage) measures (x 12 )、Upward-inclined drainage pipe(x 13 ) The score is comprehensively evaluated according to the impact of damage to the facilities on the function (the table of the impact of damage to the interception (drainage) measures on the function) and the damage range (the table of the degree of damage to the interception (drainage) measures). The score of each sub-item x is determined according to the sub-item evaluation score table of the slope protection project damage index. 11 、x 12 、x 13 The score of each item is determined according to the indicator weight coefficient value table γ 11 , γ 12 , γ 13 Finally, according to the following formula X1 = ∑x 1i γ 1i Calculate the score of slope water interception (drainage) measures (X1).

[0103]

[0104]

[0105] In the embodiment of the present application, the degree of damage to the interception (drainage) measures can be determined by the percentage of the number of damaged interception (drainage) ditches to the total number: slight damage means that the damaged number accounts for less than 20%, moderate damage means that the damaged number accounts for greater than or equal to 20% and less than or equal to 50%, and severe damage means that the damaged number accounts for more than 50%. The degree of loss can be referred to the following table for judging the degree of damage to interception (drainage) measures:

[0106]

[0107] In this embodiment, the slope protection measures (X2) can be divided into: mortar-laid rubble slope protection, lattice slope protection, and mesh protection. However, since the three slope protection measures rarely appear in one slope, the individual sub-items are not scored separately in the embodiment of this application, and all are combined into slope protection measures (X2). The score of X2 is determined according to the following table of the impact of slope protection measures damage on function, taking into account the impact of slope protection measures damage on function and the degree of damage.

[0108]

[0109]

[0110] In the embodiment of the present application, regarding the degree of damage of the slope surface protection: the mortar-laid rubble slope protection and the lattice slope protection can be determined according to the percentage of the sum of the slope protection damaged area (s) in the total slope protection area (S10); the hanging net protection can be determined according to the percentage of the sum of the protection net damaged area (s1) and the collapse area area (s2) without protection (s1+s2) in the total collapse area (S20), slight damage means that the damaged area accounts for less than 10%, moderate damage means that the damaged area accounts for greater than or equal to 10% and less than or equal to 30%, and severe damage means that the damaged area accounts for more than 30%. When only one anchor head is loose and damaged in the hanging net protection, the degree of damage of the hanging net protection is considered to be severe damage.

[0111] In one embodiment, the support and anchoring facilities (X3) can be divided into three types: retaining walls, anti-slide piles and anchor cables (rods). The present embodiment of the application evaluates only the damage of the three types of protective projects, and does not consider the design defects of each facility. The score of X3 can be determined by considering the impact of the damage of the support and anchoring facilities on the function (refer to the table of the impact of the damage of the support and anchoring facilities on the function) and the degree of damage of the support and anchoring measures (refer to the table of the degree of damage of the support and anchoring facilities).

[0112]

[0113]

[0114] In the embodiment of the present application, the degree of damage to the support and anchoring facilities can be determined based on the percentage of the number of damaged support and anchoring facilities to the total number. Specifically, slight damage means that the number of damaged facilities accounts for less than 10%, moderate damage means that the number of damaged facilities accounts for greater than or equal to 10% and less than or equal to 30%, and severe damage means that the number of damaged facilities accounts for greater than 30%. The degree of damage can be determined as shown in the following table of degree of damage to support and anchoring facilities.

[0115]

[0116] In some implementations of the embodiments of the present application, when the degree of damage of the slope protection project is not greater than a preset threshold value (such as 0.7), the degree of damage of the slope protection project can be used as the final degree of damage of the slope protection project. When the degree of damage of the slope protection project UD ≥ 0.7, it can be considered that the slope protection project (prevention and control project) has failed. At this time, the final value of the degree of damage of the slope protection project should be obtained by taking into account the comprehensive characteristic index (AP) of the slope. Specifically, when AP ≥ 0.5, UD can be set to 1.4; when AP ≤ 0.3, UD can be set to 1.0; when 0.3 < AP < 0.5, UD is taken according to the linear internal difference method.

[0117] It is understandable that when the damage degree of the slope protection project and the slope comprehensive characteristic index are determined, the slope instability index can be further determined. Based on the slope instability index, the stability level of the soil slope can be graded.

[0118] Specifically, when the slope instability index SI < 0.1, the slope danger level can be determined as level one, and the corresponding stability level is stable. At this time, the slope stability is good; when the slope instability index is 0.1≤SI<0.3, the slope danger level can be determined as level two, and the corresponding stability level is relatively stable. At this time, the slope stability is good, and there is a small probability of local soil collapse; when the slope instability index is 0.3≤SI<0.5, the slope danger level can be determined as level three, and the corresponding stability level is basically stable. At this time, the slope stability is good. In general, the possibility of overall instability is small, but there is a high probability of local soil collapse; when the slope instability index is 0.5≤SI<0.7, the slope hazard level can be determined as level four, and the corresponding stability level is understable. At this time, the slope stability is poor, and there is a possibility of overall instability, and soil collapse may occur in multiple areas; when the slope instability index SI≥0.7, the slope hazard level can be determined as level five, and the corresponding stability level is unstable. At this time, the slope stability is poor, and there is a high probability of overall instability.

[0119] The embodiment of the present application determines the cross-sectional geometric characteristics of the soil slope; determines the slope deformation and failure characteristics of the soil slope based on the slope deformation degree of the soil slope; obtains the slope failure history, surface water activity characteristics and site characteristics of the soil slope; determines the slope comprehensive characteristic index of the soil slope based on the cross-sectional geometric characteristics, slope deformation and failure characteristics, slope failure history, surface water activity characteristics and site characteristics; obtains the engineering construction time of the soil slope; determines the time factor based on the engineering construction time; determines the slope protection types included in the slope protection project of the soil slope, and sorts the importance based on the slope protection types to obtain the sorting result; assigns a weight coefficient to each slope protection type according to the sorting result; determines the weight of the slope protection type according to the weight coefficient of the slope protection type and the type failure index; determines the slope protection project failure index according to the weight of each slope protection type; determines the degree of damage of the slope protection project of the soil slope based on the time factor and the slope protection project failure index. Since the comprehensive characteristic index of the soil slope and the degree of damage of the slope protection project are determined by multiple parameters, the slope instability index compiled in the drawings is determined, which improves the accuracy of the soil slope assessment.

[0120] Based on the first embodiment and / or the second embodiment of the present application, in the third embodiment of the present application, the same or similar contents as those of the above-mentioned first embodiment and / or the second embodiment can refer to the above introduction, and will not be repeated later. Figure 6 , Figure 6 A flow chart of the third embodiment of the method for assessing the safety risk level of soil slopes in the present application is provided. In the embodiment of the present application, the step of determining the slope hazard hazard index of the soil slope includes:

[0121] Step S51, determining a facility score at the top of the soil slope based on the type of infrastructure at the top of the soil slope, the characteristic height of the slope, and the distance between the facility and the top of the slope;

[0122] Step S52, determining a score of facilities at the foot of the soil slope based on the type of infrastructure at the foot of the soil slope, the characteristic height of the slope, the distance between the facilities and the foot of the slope, and the terrain characteristics of the slope;

[0123] Step S53, determining the slope disaster-bearing body grade score of the soil slope and the degree of harm after the soil slope becomes unstable;

[0124] Step S54, determining the score of the group of people affected by the soil slope;

[0125] Step S55, determining the slope hazard hazard index of the soil slope based on the slope top facility score, the slope foot facility score, the slope hazard-bearing body grade score, the hazard degree and the slope disaster-affected population score.

[0126] In the embodiment of the present application, the slope hazard index CS of the soil slope can be determined based on the following formula:

[0127]

[0128] Among them, F1 represents the score of facilities at the top of the slope, F2 represents the score of facilities at the foot of the slope, G1 represents the score of the disaster-bearing body grade of the slope, G2 represents the score of the degree of hazard, and I represents the score of the affected population.

[0129] It should be noted that when obtaining the score for slope top facilities, the slope top infrastructure type F can be considered. s , slope characteristic height H0, and the distance between the facility and the top of the slope L1. Specifically, the top facility score can be calculated based on the following formula:

[0130] F1=F s (2H0-L1) / (2H0);

[0131] In one implementation, if the facility is set on a slope, the facility score F1 on the top of the slope can be set to Fs.

[0132] Among them, the slope top facility type F s The values ​​can be taken based on the following score table of facilities around the slope:

[0133]

[0134] It should be noted that when there are multiple facilities around the slope, the score of each facility can be calculated separately and the maximum value can be taken. When the calculated value is less than zero, it is taken as zero.

[0135] In one implementation, the foot of slope facility score can be determined by considering four influencing factors: the type of infrastructure at the foot of the slope Fw, the characteristic height of the slope H0, the distance of the facility to the foot of the slope L2, and the terrain characteristics of the slope Js. The specific calculation method can refer to the formula shown below:

[0136]

[0137] Among them, the slope foot facility type Fw is determined based on the importance of the facility (the specific value can be found in the score table of facilities around the slope), and the slope characteristic height H0 and the distance L1 from the facility to the top of the slope are obtained based on the on-site investigation of the slope. The topographic characteristics Js of the slope comprehensively consider the influence of the slope elevation angle and slope height. The specific value can be found in the slope topographic characteristics table shown below:

[0138]

[0139] In one implementation, the slope hazard-bearing body grade score can be determined based on the slope hazard-bearing body grade. For details, refer to the slope hazard-bearing body grade score table shown below:

[0140]

[0141] It should be noted that the above-mentioned slope disaster-bearing body grades can be divided according to the scale of the slope disaster-bearing body in actual applications, and the embodiments of the present application are not limited to this.

[0142] In one implementation, the impact of slope instability on the hazard-bearing body, that is, the degree of hazard of the slope, can be determined by referring to the following score table of the degree of hazard of the slope to the hazard-bearing body:

[0143]

[0144] In one implementation, the degree of threat posed by the slope disaster to the population nearby can be scored, that is, the score of the affected population can be obtained. The degree of threat can take into account two influencing factors: the number of households near the slope and the distance from the foot of the slope. The specific calculation method of the score of the affected population can refer to the following table of scores of the affected population:

[0145]

[0146] The embodiment of the present application obtains the number of households within a preset disaster-affected range of the soil slope (such as within 50m, within 20m, etc.), and divides the preset disaster-affected range into 4 disaster-affected range intervals (in meters), namely w<10, 10≤w<20, 20≤w<50, w≥50. According to the number of households in each disaster-affected range interval, the score of the affected population of the soil slope can be determined. That is, the step of determining the score of the slope affected population of the soil slope includes: obtaining the preset disaster-affected range of the soil slope; dividing the preset disaster-affected range into a number of disaster-affected range intervals; determining the score of the slope affected population of the soil slope according to the number of households in each of the disaster-affected range intervals.

[0147] The embodiment of the present application determines the top facility score of the soil slope based on the type of infrastructure at the top of the soil slope, the characteristic height of the slope, and the distance between the facility and the top of the slope; determines the foot facility score of the soil slope based on the type of infrastructure at the foot of the soil slope, the characteristic height of the slope, the distance between the facility and the foot of the slope, and the terrain characteristics of the slope; determines the slope disaster-bearing body grade score of the soil slope and the degree of harm after the soil slope becomes unstable; determines the slope disaster-affected population score of the soil slope; and determines the slope disaster hazard index of the soil slope based on the top facility score, the foot facility score, the slope disaster-bearing body grade score, the degree of harm, and the slope disaster-affected population score. Because the stability of the slope is preliminarily evaluated by collecting and analyzing the multi-dimensional data of the slope, and the safety risk level of the slope is comprehensively evaluated in combination with the slope protection project and the slope hazard index, multiple aspects of data are integrated to improve the accuracy of the safety assessment.
