Detailed implementation manners

[0013] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following describes the detailed implementation manners of the present invention in conjunction with the accompanying drawings. Many specific details are set forth in the following description to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0014] Refer to Figure 1 , an embodiment of the present invention provides a method for selecting a location for a road emergency equipment depot, including the following steps: Step 1: Evaluate the road fracture risk of the target area based on four dimensions of flood, geology, earthquake, and soil erosion, set the weights of each dimension, and obtain the evaluation result of the road fracture risk of the target area.

[0015] Step 2: According to the evaluation result and the weights, use spatial analysis GIS for overlay analysis to determine the road fracture risk scoring raster result of the target area; correspond the risk values in the road fracture risk scoring raster result of the target area to the break points of the road, and determine the fracture risk of the road according to the risk values at the break points of the road. Take the break points of the roads whose fracture risk meets the first set threshold as risk request points; take the break points of the roads whose risk values are less than the second set threshold as preliminary facility candidate points, and take residential areas, gas stations, toll stations, service areas, and road maintenance stations as supplementary facility candidate points. Combine the preliminary facility candidate points and the supplementary facility candidate points to form potential facility candidate points for the road emergency equipment depot.

[0016] Step 3: To ensure that the risk request points obtain responses from potential facility candidate points within the preset response time, use GIS site selection analysis for site selection of the road emergency equipment depot with the goal of maximizing the coverage range and minimizing the number of facilities.

[0017] The specific content of the present invention is as follows: S101. Construct a comprehensive evaluation index system for road fracture risk based on four dimensions of flood, geology, earthquake, and soil erosion. The weights assigned to the four dimensions are sorted from large to small as: flood, geology, soil erosion, and earthquake.

[0018] The comprehensive evaluation result of the road disaster risk of the target layer needs to first assign weights to the four risks of the first-level indicators and add them together. The assigned weights are: 4 for flood, 3 for geology, 2 for soil erosion, and 1 for earthquake.

[0019] The risk of flood disaster is the main factor causing road fractures in the region. In view of the situation that the road damage in flood disasters is mainly caused by river breaches and flood outflows, the present invention uses the method of distance buffer to simulate the overflooding of rivers in flood disasters, and evaluates the standardized flood disaster risk according to the distance level.

[0020] The risk of geological disasters is the comprehensive analysis result of geological disaster-prone areas and prone points. The distribution map of prone areas is registered and the kernel density value of prone points is calculated, and then GIS overlay analysis is used and the standardized average value is taken as the result of geological disaster risk.

[0021] Use the national active fault zone and national peak ground acceleration data for risk assessment. Overlay and analyze the two, and take the highest level among the active fault distance risk and the peak ground acceleration risk of earthquake as the result of earthquake disaster risk, as shown in Table 1 and Table 2.

[0022] Table 1 is the risk level of the fault zone distance.

[0023]

[0024] Table 2 is the risk level of the peak ground acceleration of earthquake.

[0025]

[0026] For soil erosion assessment, the present invention calculates each factor and the final result of the RUSLE model, and uses the quantile method to divide it into six erosion levels, namely slight, light, moderate, strong, very strong and severe erosion, as shown in Table 3, and finally obtains the standardized soil erosion risk result.

[0027] Table 3 is the classification table of soil erosion modulus.

[0028]

[0029] S102. Use the index system to evaluate the fracture risk of the road system in the target area; among them, the dimensions of soil erosion include slope factor, slope length factor, rainfall erosivity factor, soil erodibility factor, vegetation coverage factor and soil and water conservation measure factor.

[0030] In the temperature of soil erosion, the soil erosion modulus is expressed as: A = H * R * K * C * P; where A represents the soil erosion modulus, H is the topographic relief factor, R is the rainfall erosivity factor, K is the soil erodibility factor, C is the vegetation coverage factor, and P is the soil and water conservation measure factor.

[0031] In the terrain undulation factor H, it is calculated using the DEM elevation data, and the formula is as follows: H = Hmax - Hmin; where: H is the terrain undulation factor, Hmax is the maximum elevation value, and Hmin is the minimum elevation value.

[0032] In the precipitation erosivity factor R, it is calculated using the following formula: .

[0033] Among them, Ra is the precipitation erosivity in the a-th year, Pa is the precipitation in the a-th year, α and β are parameters in the model, α = 0.0534, and β = 1.6548.

[0034] The soil erodibility factor K is calculated using the EPIC model for the soil texture data of this area, and the formula is as follows: .

[0035] In the formula: SAN is sand grains, in units of %; SIL is silt, in units of %; CLA is clay, in units of %; C is the organic carbon in the soil, in units of %; SN = 1 - SAN / 100.

[0036] The calculation formula of the vegetation coverage factor C is expressed as follows: .

[0037] In the formula: C is the vegetation coverage factor; c is the vegetation coverage.

[0038] In the calculation of the soil and water conservation measure factor P, it is assigned with reference to the land use situation to obtain the soil and water conservation measure factor, as shown in Table 4: Table 4 is the assignment table of the soil and water conservation measure factor.

[0039]

[0040] S103. Through the overlay analysis operation of the GIS spatial analysis module on the evaluation results, determine the grid results of each risk dimension and the comprehensive risk result, and perform weighted addition on the four evaluation results to obtain the grid result of the road fracture risk score in the target area, and determine the risk request points and potential facility candidate points according to the score grid result.

[0041] S104. Import the risk request points and potential facility candidate points, and use the maximum coverage range and minimum number of facilities model for site selection analysis to obtain the site selection result of the road emergency equipment depot.

[0042] Among them, the GIS network analysis is used to select the location of the road emergency equipment depot; a traffic network dataset is constructed based on the processed road network, and the impedance is set. Most road emergency equipment, such as loaders and tractors, has a maximum speed of about 30 - 40 km / h. To ensure that the request point receives the response of the emergency equipment within 1 hour in case of an emergency, the minimum speed is set to 30 km / h, that is, the road impedance value is 30000 m.

[0043] In one implementation manner of the present invention, in the step of determining the risk request point and the potential facility candidate point according to the scoring grid result: The grid risk value is extracted into the road break points through spatial analysis, and the risk of the road where the break point is located is judged according to the break point risk value, so as to obtain the set of request points under different disaster levels.

[0044] According to the road safety, the road segments with a risk value less than 0.06 are selected as the roads where the site can be selected, and the midpoints of them are used as the preliminary facility candidate points; in addition, the residential areas, gas stations, toll stations, service areas and existing road maintenance stations in the target area POI data are supplemented as the eligible facility candidate points to obtain the potential facility candidate points.

[0045] Therefore, the present invention uses the GIS spatial analysis module to implement operations such as calculating and overlaying analysis on specific spatial data elements, including functions such as spatial query and measurement, buffer analysis, overlay analysis, and spatial interpolation; further, through the GIS overlay analysis operation, the grid results of each risk dimension and the comprehensive risk result can be determined, and the four evaluation results are weighted and added to obtain the standardized road fracture risk scoring grid result of a certain area; before determining the site selection operation, using the GIS spatial analysis and data management functions is a key step, which mainly involves two categories: risk request points and potential facility candidate points that may be used as site selection points.

[0046] The risk request point refers to the road fracture point when a disaster occurs, which is divided into 7 levels according to different disaster levels. The grid risk value is extracted into the road break points through spatial analysis, and then the risk of the road where the break point is located is judged according to the break point risk value, so as to obtain the set of request points under three different disaster levels.

[0047] The sources of potential facility candidate points include relatively safe roads and existing highway-related facilities. According to the road safety, the road segments with a risk less than 0.06 are selected as the roads where the site can be selected, and the midpoints of them are used as the preliminary facility candidate points. In addition, the locations of residential areas, gas stations, toll stations, service areas, etc. in the target area POI data, as well as data such as existing road maintenance stations, are supplemented as the eligible facility candidate points, with a total of 441 potential facility candidate points.

[0048] The present invention imports risk request points and potential facility candidate points, and uses a model of maximizing the coverage range and minimizing the number of facilities for site selection analysis to ensure that the site selection result is as few as possible and the coverage range is as large as possible.

[0049] In summary, the method for site selection of road emergency equipment depots based on multi-dimensional risk assessment provided by the present invention can comprehensively evaluate the road fracture risk, and propose effective site selection and design schemes for equipment depots to cope with the challenges that may be brought by various natural disasters in the research area.

According to the score grid result, risk request points and potential facility candidate points are determined; the risk request points and potential facility candidate points are imported, and a model of maximizing the coverage range and minimizing the number of facilities is used for site selection analysis to obtain the site selection result of the road emergency equipment depot. The present invention can comprehensively evaluate the road fracture risk and propose effective site selection and design schemes for equipment depots to cope with the challenges that may be brought by various natural disasters in the research area.
