[0025] Please refer to Figure 1 , which shows the process of an embodiment of the method for evaluating the resilience of highways in disaster-prone mountainous areas according to the present disclosure.

[0026] like Figure 1 As shown, the survey method based on BIM fusion includes the following steps: Step 100: Based on the entropy weight method, establish indicator data for the evaluation object, collect and process data based on the indicator data, and standardize the collected data.

[0027] Here, it is assumed that the specific value of the collected indicator data is X; By finding the indicator data and , for each indicator data , subtract it , get the corresponding difference, and then divide the difference by minus The result is the standardized data, that is, , its specific value range is between; If you need to substitute a numerical value for indicator calculation; Suppose there is a set of indicator data that needs to be standardized and calculated; By finding and , for each indicator data , subtract it ; Divide the difference by minus ; After reducing the fraction, the specific standardized value is obtained: The processed data can eliminate the dimensional differences between different indicators, making them more accurate when compared and analyzed on the same scale.

[0028] Step 200: Based on the obtained data, a numerical terrain model method is adopted, and a triangulation interpolation and fitting technology is used to collaboratively establish a highway model.

[0029] Here, the model is established based on the data obtained after collection and processing, and the triangular interpolation method is used; According to the location of discrete data points, the data points are connected into a triangular mesh using a triangulation algorithm, and then the given interpolation points are , you need to calculate its centroid coordinates in each triangle; Among them, the triangulation algorithm in the above content adopts Triangulation; Specifically: take the point set to be segmented as input and create a super triangle that contains all the points. The vertices of the super triangle must be guaranteed to contain all the points and exceed the boundary of the point set; Iterative subdivision: For each point, iterative subdivision is performed according to the following steps; first, find the triangle containing the current point: starting from the super triangle, check each triangle and find the triangle containing the current point; second, delete the triangles related to the current point: starting from the found triangle containing the current point, delete these triangles; then, build new triangles: for each edge of the deleted triangle, if the edge has no shared adjacent triangles, build a new triangle connecting the current point with the two vertices of the edge.

[0030] The triangles formed during the subdivision process may intersect with the boundaries of the super triangle. Therefore, these triangles that intersect with the boundaries of the super triangle need to be deleted. After the subdivision is completed, the output result is a set of non-overlapping triangles that satisfy condition.

[0031] Here, the barycentric coordinates are composed of three weights Express, satisfy ; For triangle : In the formula, is the interpolation point and the area of ​​the triangle, , , The triangle area; Based on the barycentric coordinates and the values ​​of discrete data points, interpolation calculations can be performed.

After interpolation and fitting processing, a highway model is generated, and a visualization mapping is provided for the generated highway model based on the visualization module.

[0032] Step 300: Based on the processed data, entropy values ​​are calculated for the indicator data, and for each different indicator, the amount of information or uncertainty is calculated and measured.

[0033] Here, Shannon entropy is used to measure the degree of discreteness of data. The larger the value, the more dispersed the data is, and vice versa, the more concentrated the data is. In the formula, Indicator The information entropy of Indicates the number of different values ​​of the indicator. Indicator In the value The probability of being at Assume that pavement shear strength is selected as the indicator data, and the following data are collected: First, calculate the frequency of each value: Substitute into the Shannon entropy formula for calculation: According to the calculated information entropy value, subsequent weight calculation can be performed according to the obtained information entropy value.

[0034] Step 400: Based on the indicator data after entropy value calculation, weight calculation is performed on the indicator data, and the weights are normalized to ensure that the sum of the weights is 1.

[0035] Here, based on the entropy weight method, the information entropy value is used to calculate the weight of each indicator. The weight is calculated based on the information entropy of the indicator and is determined using the normalized form of the information entropy value. In the formula, Indicator The weight of Indicator The information entropy of Indicates the total number of indicators; Assume that there are three indicators: pavement shear strength, pavement layer thickness and pavement crack resistance, and their information entropy values ​​have been calculated: , , ; Substitute the above information entropy value into the weight calculation formula: The weight value of each indicator is calculated by the above formula.

[0036] Step 500: Based on the weight and entropy value calculation results, the normalized weight is applied to the evaluation results of each indicator to obtain a comprehensive evaluation process.

[0037] Here, specifically include: When the standardized indicator data is multiplied by the corresponding weight and summed to obtain the final comprehensive evaluation result, the weighted summation calculation formula is used; In the formula, Indicates the comprehensive evaluation results. Represents the standardized indicator data, represents the corresponding weight, and n represents the total number of indicators; Assume that there are three indicators, namely, pavement shear strength, pavement layer thickness and pavement crack resistance, and the indicators have been standardized and calculated to obtain the corresponding weight values; , , , , , Multiply the standardized indicator data by the corresponding weight and sum them up: The comprehensive evaluation result R is obtained by calculation, which represents the evaluation value of pavement toughness; If other index data need to be calculated, such as the road surface water erosion resistance performance, the road surface water erosion resistance performance can be set as P, and it can also be calculated by the formula: Where P represents the road surface's water erosion resistance. Represents the standardized indicator data, Represents the corresponding weight, and n represents the total number of indicators.

[0038] Step 600: Based on the weight and entropy value calculation results, the normalized weight is applied to the evaluation results of each indicator to obtain a comprehensive evaluation process.

[0039] The present application provides a method for assessing the resilience of highways in disaster-prone mountainous areas. The entropy weight method is used to establish index data for the assessment object. The data is collected and standardized based on the index data. A numerical terrain model method is used based on the obtained data, and a highway model is jointly established using triangulated network interpolation and fitting technology. The entropy value of the index data is calculated based on the standardized data, and the weight is calculated based on the calculated index data. The weight is normalized to ensure that the sum of the weights is 1. Based on the weight and entropy calculation results, the normalized weight is applied to the assessment results of each indicator to obtain a comprehensive assessment process, output an assessment report, and visualize the report. Through resilience assessment, the weaknesses and vulnerabilities of the highway system are determined, and an assessment report is provided to decision makers, thereby improving and strengthening the disaster resistance of highways.
