Embodiment Construction

[0028] The tailings dam safety level assessment method based on the two-dimensional cloud model includes the following steps:

[0029] Step 1: Establish an evaluation index system, such as figure 2 As shown, the weighted fusion method is used to synthesize the sensor monitoring data and expert evaluation data of various types of data evaluation data, and obtain the fusion distribution of the two types of data evaluation data, that is, to obtain the expert evaluation module and sensor monitoring module in, Indicates the i-th expert evaluation sub-module; W Ei Represents the weight matrix of the i-th expert evaluation module; Indicates the amount of the jth sensor sub-module; W Sj Indicates the weight matrix of the jth sensor evaluation sub-module.

[0030] Step 2: Pass the expert assessment module and sensor monitoring module The results of each evaluation level construct the rules for judging the safety level of tailings dams.

[0031] Step 3: Obtain the digit...

Abstract

The invention belongs to the field of assessment of actual projects such as large-scale buildings, public facilities and precision equipment, and particularly provides a tailing dam safety level assessment method based on a two-dimensional cloud model. According to the method, a two-dimensional cloud model scale and a two-dimensional evaluation cloud model projection are used for evaluating the relation between data security level scales in the joint evaluation of heterogeneous data, and the similarity measure coefficient between two-dimensional cloud models is used for determining the evaluation result of the security level. Experimental results show that according to the tailing dam risk assessment method based on the two-dimensional cloud model, randomness and fuzziness of expert prediction module data and sensor module data obtained in assessment are processed at the same time, and support is provided for qualitative and quantitative accuracy of the data.

Description

technical field [0001] The invention belongs to the evaluation field of actual projects such as large buildings, public facilities, and precision equipment, and specifically relates to a tailings dam safety level evaluation method based on a two-dimensional cloud model. Background technique [0002] Expert prediction data and sensor monitoring data reflect the actual project (such as large buildings, public facilities, precision equipment, etc.) important safeguards that occur. However, since the number of evaluation items and their evaluation sub-items in each module varies according to the pre-defined evaluation level requirements, and different evaluation personnel or experts have different understandings of different evaluation items, this brings great impact on the evaluation data. uncertainty. Therefore, the evaluation of the safety level of tailings dams is very important to deal with the uncertainty of expert prediction data and sensor monitoring data. [0003] Th...
