[0062] The purpose, features and advantages of this application will be further described in conjunction with the embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0063] 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.

[0064] 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.

[0065] The main solution of the embodiment of the present application is: based on the slope characteristics of the rock slope, determine whether there is an unstable fatal factor in the rock slope; when there is an unstable fatal factor, use a preset value as the slope instability index of the rock slope; when there is no unstable fatal factor, obtain the slope comprehensive characteristic index of the rock slope and the degree of damage to the slope protection project; determine the slope instability index of the rock slope based on the slope comprehensive characteristic index of the rock slope and the degree of damage to the slope protection project; determine the slope disaster hazard index of the rock slope; determine the safety risk level of the rock slope based on the slope instability index and the slope disaster hazard index.

[0066] At present, remote sensing technology and ground monitoring technology are usually used to identify various potential risks that may exist in slopes, such as unstable geological structures, natural factors such as rainfall, and human factors such as land development and engineering construction. The risk level of rock slope stability is quantitatively analyzed through the above potential risks, and the risk assessment results are determined to determine the priority and urgency of governance, and then the corresponding governance plan is formulated, including engineering governance measures (such as reinforcement, drainage, etc.) and non-engineering governance measures (such as early warning systems, emergency plans, etc.).

[0067] However, at present, a single safety factor is usually used as the evaluation criterion in rock slope risk assessment, without considering the uncertainty, randomness and interaction of multiple factors. This may lead to problems in the control plan during long-term use and cannot be discovered and solved in time.

[0068] 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 rock slopes (hereinafter referred to as the assessment device) as an example to illustrate this embodiment and the following embodiments.

[0069] Based on this, the present application embodiment provides a method for assessing the safety risk level of a rock slope. Figure 1 and Figure 2 , Figure 1 This is a flow chart of the first embodiment of the method for assessing the safety risk level of a rock slope in the present application. Figure 2 The figure is a schematic diagram of the overall process in one implementation of the present application.

[0070] In this embodiment, the rock slope safety risk level assessment method includes steps S10 to S40:

[0071] Step S10, determining whether there is an unstable fatal factor in the rock slope based on the slope characteristics of the rock slope;

[0072] It can be understood that a slope is a slope formed naturally or artificially, which is composed of the top, surface, foot and a slope within a certain depth range below the surface line, and has a certain height, slope and extension width. A rock slope is a slope composed of various rocks (such as sedimentary rocks, igneous rocks, metamorphic rocks, etc.).

[0073] 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 rock slope. The identification method may be a machine learning method or other methods, which are not limited in the embodiments of the present application.

[0074] It needs to be explained that, in order to evaluate the instability of the rock 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 rock slope. Once this factor appears in the rock slope, the safety risk level increases.

[0075] 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 continuous open cracks extending at the rear edge of the slope (such as an opening greater than 0.5m); longitudinal shear cracks on the slope surface, such as a large number of longitudinal shear cracks visible on the slope surface; deformation and displacement of the slope rock mass, such as large-scale deformation and displacement of the slope rock mass (the specific range value can be determined according to the scale of the rock slope); and suspended dangerous rock mass on the slope, such as large suspended dangerous rock mass (volume ≥50m 3); it can also include the retaining wall condition of the slope protection project, such as any obvious bulging, tilting or dislocation of the retaining wall in the protection project; it can also include the anti-sliding pile condition and anchor cable (rod) condition of the slope protection project, such as any obvious bulging, tilting or bending of the anti-sliding pile, or any broken steel bar (strand) of the anchor cable (rod), or any obvious damage or detachment of the anchor head.

[0076] It should be noted that the instability fatality factor can be planned based on the rock slope conditions in actual applications, and the embodiments of the present application do not impose specific restrictions on it.

[0077] In practical applications, if any unstable fatal factor appears, the rock slope can be considered unstable, and the slope instability index SI of the corresponding rock 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 rock slope.

[0078] Step S30, when the unstable fatal factor does not exist, obtaining the slope comprehensive characteristic index and the damage degree of the slope protection project of the rock slope;

[0079] Step S40: determining the slope instability index of the rock slope based on the comprehensive slope characteristic index of the rock slope and the damage degree of the slope protection project.

[0080] It should be noted that when there is no fatal instability factor in the rock slope, the slope instability index can be calculated based on the following formula:

[0081] SI = AP × UD;

[0082] Among them, SI is the slope instability index, AP is the comprehensive characteristic index of rock slope, and UD is the damage degree of rock slope protection project.

[0083] It should be noted that the above-mentioned comprehensive characteristic index of rock slope is an index that can be used to describe and quantify various characteristics of rock slope, which may include geometric characteristics, deformation characteristics, damage characteristics, groundwater characteristics, damage mode characteristics, damage scale characteristics, etc., and the embodiments of the present application are not limited to this.

[0084] It is understandable that in some rock slopes, protective engineering measures may be built, namely rock slope protection engineering. Due to the influence of natural factors or human factors, the rock slope protection engineering will have a certain degree of damage, and the rock slope protection engineering damage degree can be a parameter used to describe its degree of damage.

[0085] Step S50, determining the slope hazard hazard index of the rock slope;

[0086] Step S60: determining the safety risk level of the rock slope based on the slope instability index and the slope disaster hazard index.

[0087] 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 disasters on rock slopes. By evaluating the safety level of rock slopes through the slope variable stability index and the slope disaster hazard index, the stability, danger and degree of danger in the rock slope assessment process can be comprehensively considered, thereby achieving a more accurate safety level classification.

[0088] In some implementations of the present application, the safety risk assessment of the rock slope can be calculated based on the following formula:

[0089] RS = SI × CS;

[0090] Among them, RS is the slope safety risk assessment score, SI is the slope instability index, and CS is the slope disaster hazard index.

[0091] In some implementations of the embodiments of the present application, the safety risk level of the rock 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 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 risk level can be identified as orange (i.e., high risk). When 0.1≤RS<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 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 risk level can be identified as blue (i.e., low risk).

[0092] The embodiment of the present application determines whether there is an unstable fatal factor in the rock slope based on the slope characteristics of the rock slope; when there is an unstable fatal factor, a preset value is used as the slope instability index of the rock slope; when there is no unstable fatal factor, the slope comprehensive characteristic index and the damage degree of the slope protection project of the rock slope are obtained; the slope instability index of the rock slope is determined based on the slope comprehensive characteristic index of the rock slope and the damage degree of the slope protection project; the slope disaster hazard index of the rock slope is determined; the safety risk level of the rock 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 in the rock slope are determined, a comprehensive assessment of the rock slope is achieved, and the accuracy of the safety level risk assessment is improved.

[0093] 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 embodiment of the present application, the step of obtaining the comprehensive slope characteristic index of the rock slope and the degree of damage of the slope protection project includes:

[0094] Step S31, determining the cross-sectional geometric features of the rock slope based on the slope height and slope gradient of the rock slope;

[0095] Step S32, determining the slope deformation and failure characteristics of the rock slope based on the slope deformation degree of the rock slope;

[0096] Step S33, obtaining the slope failure history and groundwater seepage characteristics of the rock slope;

[0097] Step S34, determining the failure mode of the rock slope and the failure scale under the failure mode;

[0098] Step S35, determining the instability probability of the rock slope based on the structural surface characteristics of the rock slope;

[0099] Step S36, determining a comprehensive slope characteristic index of the rock slope based on the cross-sectional geometric characteristics, the slope deformation and failure characteristics, the slope failure history, the groundwater seepage characteristics, the failure mode, the failure scale, and the instability probability;

[0100] Step S37, obtaining the damage degree of the slope protection project of the rock slope.

[0101] In some implementations of the present application, the method for calculating the slope comprehensive characteristic index AP may be as follows:

[0102] AP=(A+B1+B2+C+D+D1×D2) / 100;

[0103] Among them, A is the characteristic score of the cross-section geometric characteristics, B1 is the characteristic score of the slope deformation and failure characteristics, B2 is the characteristic score of the slope failure history, C is the characteristic score of the groundwater seepage characteristics, D1 is the characteristic score corresponding to the failure mode and failure scale, and D2 is the characteristic score corresponding to the instability probability.

[0104] 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 rock 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.

[0105] In some implementations of the present application, the cross-sectional geometric features may include the slope height H, the slope bottom angle α, the slope gradient θ, and the slope height H of the rock slope. r , the average slope θ of the slope, the weight of the covering layer γ, etc., which are not limited in the embodiments of the present application. Based on the cross-sectional geometric features of the rock 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, which are not limited in the embodiments of the present application.

[0106] In some implementations of the embodiments of the present application, the characteristic score A of the slope cross-section geometric feature can be obtained by the following slope cross-section geometric feature characteristic score query table:

[0107]

[0108] In some implementations of the present application, the slope deformation degree of the rock slope can be determined by field investigation or historical data analysis, and the slope deformation failure characteristics can be determined based on the slope deformation degree. The characteristic score B1 of the slope deformation failure characteristics can be determined by referring to the following slope deformation failure characteristics characteristic score query table:

[0109]

[0110] In some implementations of the present application, the slope failure history of the rock 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 landslide: refers to the landslide that can be confirmed by relevant document records; possible landslide: refers to the landslide that is not recorded in documents but is speculated based on geological surveys or exploration methods; severe landslide: refers to the landslide volume ≥50m 3 ; or landslide volume ≥ 25m 3And 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:

[0111]

[0112] In some implementations of the present application, for the slope instability index of the slope, the hydrological conditions of the rock slope can also be considered. The present application embodiment takes the groundwater seepage effect as an example to illustrate the method of the present application. Specifically, the characteristic score C corresponding to the groundwater seepage characteristic can be determined based on the following groundwater seepage characteristic characteristic score query table:

[0113]

[0114] In some implementations of the present application, the characteristic score D1 corresponding to the slope failure mode and failure scale can be determined by the following failure mode and scale characteristic score query table:

[0115]

[0116] It can be understood that slope instability is the situation where the rock slope loses stability due to toppling, landslide, collapse, etc. under the influence of internal and external adverse factors. In some implementations of the embodiments of the present application, the probability of slope instability can be used as a parameter for evaluating the instability index of the rock slope. Specifically, the characteristic value D2 corresponding to the probability of instability of the rock slope can be obtained based on the following instability probability characteristic value query table:

[0117]

[0118] It should be understood that the structural surface characteristics of the rock slope can be determined based on remote sensing technology, infrared technology, etc., and the embodiments of the present application are not limited to this.

[0119] It should be noted that protective engineering measures may be built on some rock slopes, and the slope protection engineering damage degree can be used as a parameter for evaluating the degree of damage of the protective engineering measures. For rock slopes without protective engineering measures, the slope protection engineering damage degree UD can be set to 1.0. For rock slopes with protective engineering measures, the step of obtaining the slope protection engineering damage degree of the rock slope includes: obtaining the engineering construction time of the rock slope; determining the time factor based on the engineering construction time; determining the slope protection types included in the slope protection engineering of the rock 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 rock slope based on the time factor and the slope protection engineering damage index.

[0120] Specifically, the step of determining the damage degree of the slope protection project of the rock slope based on the time factor and the slope protection project damage index includes: determining the initial slope protection project damage degree of the rock 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 rock 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 rock slope based on the index interval of the slope comprehensive characteristic index. The specific calculation formula can be as follows:

[0121]

[0122] 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, K can be taken as 1.4.

[0123] 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:

[0124]

[0125] In some implementations of the embodiments of the present application, in order to determine the slope fire protection engineering damage index US, it is possible to first determine which slope protection types are included in the slope protection engineering of the rock 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.

[0126] 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 ).

[0127] In one implementation of an embodiment 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.

[0128] 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.

[0129]

[0130]

[0131]

[0132]

[0133] In some implementations of the present application, if one or more water interception (drainage) measures appear in the rock 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 ).

[0134] 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).

[0137] 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 20%-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:

[0138]

[0139] 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.

[0140]

[0141] 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) to the total slope protection area (S); the hanging net protection can be determined according to the percentage of the sum of the damaged area of ​​the protection net (s1) and the area of ​​the collapse area without protection (s2) (s1+s2) to the total collapse area (S), slight damage means that the damaged area accounts for less than 10%, moderate damage means that the damaged area accounts for 15% 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.

[0142] 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).

[0143]

[0144]

[0145] 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 10% to 30%, and severe damage means that the number of damaged facilities accounts for more than 30%. The degree of damage can be determined as shown in the following table of degree of damage to support and anchoring facilities.

[0146]

[0147] 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 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.

[0148] 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 rock slope can be graded.

[0149] The embodiment of the present application determines the cross-sectional geometric characteristics of the rock slope based on the slope height and slope gradient of the rock slope; determines the slope deformation and failure characteristics of the rock slope based on the slope deformation degree of the rock slope; obtains the slope failure history and groundwater seepage characteristics of the rock slope; determines the failure mode of the rock slope and the failure scale under the failure mode; determines the instability probability of the rock slope based on the structural surface characteristics of the rock slope; determines the comprehensive slope of the rock slope based on the cross-sectional geometric characteristics, slope deformation and failure characteristics, slope failure history, groundwater seepage characteristics, failure mode, failure scale and instability probability. The invention relates to a method for determining a slope protection project of a rock slope by combining a characteristic index; obtaining a construction time of the rock slope; determining a time factor based on the construction time; determining the slope protection types included in the slope protection project of the rock slope, and ranking the slope protection types by importance to obtain a ranking result; assigning a weight coefficient to each slope protection type according to the ranking result; determining the weight of the slope protection type according to the weight coefficient of the slope protection type and the type damage index; determining the slope protection project damage index according to the weight of each slope protection type; determining the degree of damage of the slope protection project of the rock slope based on the time factor and the slope protection project damage index.

[0150] 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 5 In the embodiment of the present application, the step of determining the slope hazard hazard index of the rock slope includes:

[0151] Step S51, determining a facility score at the top of the rock slope based on the type of infrastructure at the top of the rock slope, the characteristic height of the slope, and the distance between the facility and the top of the slope;

[0152] Step S52, determining the infrastructure score at the foot of the rock slope based on the type of infrastructure at the foot of the rock slope, the characteristic height of the slope, the distance between the infrastructure and the foot of the slope, and the terrain characteristics of the slope;

[0153] Step S53, determining the slope disaster-bearing body grade score of the rock slope and the degree of harm after the rock slope becomes unstable;

[0154] Step S54, determining the score of the population affected by the rock slope;

[0155] Step S55, determining the slope hazard hazard index of the rock 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.

[0156] In the embodiment of the present application, the slope hazard index of the rock slope can be determined based on the following formula:

[0157]

[0158] 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.

[0159] It should be noted that when obtaining the score of the top facilities, three influencing factors can be considered: the type of infrastructure on the top of the slope Fs, the characteristic height of the slope H0, and the distance of the facilities from the top of the slope L1. Specifically, the score of the top facilities can be calculated based on the following formula:

[0160] F1=F s (2H0-L1) / (2H0);

[0161] 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.

[0162] The slope top facility type Fs can be obtained based on the slope surrounding facility score table as shown below:

[0163]

[0164] 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.

[0165] 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:

[0166]

[0167] 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:

[0168]

[0169]

[0170] 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:

[0171]

[0172] 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.

[0173] 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:

[0174]

[0175] 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:

[0176]

[0177]

[0178] The embodiment of the present application obtains the number of households within a preset disaster-affected range of the rock slope (such as 100m, 50m, etc.), and divides the preset disaster-affected range into four disaster-affected distance intervals, namely less than 10m, 10-19m, 20-50m, and greater than 50m. According to the number of households in each disaster-affected distance interval, the score of the affected population of the rock slope can be determined. That is, the step of determining the score of the affected population of the rock slope includes: obtaining the preset disaster-affected range of the rock slope; dividing the preset disaster-affected range into a number of disaster-affected distance intervals; determining the score of the affected population of the rock slope according to the number of households in each of the disaster-affected range intervals.

[0179] The embodiment of the present application determines the top facility score of the rock slope based on the type of infrastructure at the top of the rock 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 rock slope based on the type of infrastructure at the foot of the rock 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 grade score of the rock slope's hazard-bearing body and the degree of harm after the rock slope becomes unstable; determines the score of the affected population of the rock slope; and determines the slope disaster hazard index of the rock slope based on the top facility score, the foot facility score, the slope hazard-bearing body grade score, the degree of harm, and the score of the affected population. The stability of the slope is preliminarily evaluated by collecting and analyzing the geological survey data, historical deformation monitoring data, meteorological data, remote sensing data, etc. of the slope; and the safety risk level of the slope is comprehensively evaluated in combination with the slope protection project and the slope disaster hazard index. By integrating multiple aspects of data, the accuracy of the safety assessment is improved.
