Embodiment Construction

[0034] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with the embodiments and accompanying drawings. The embodiments are only used to explain the present invention, and do not constitute a limitation to the protection scope of the present invention.

[0035] see figure 2 As shown, a comprehensive evaluation method for dam safety includes the following steps:

[0036] ①According to the SL258-2000 "Guidelines for Reservoir Dam Safety Evaluation" issued by the Ministry of Water Resources in 2000, build a hierarchical structure model of the dam safety system, determine the criteria and factors for the dam safety evaluation, and divide the dam safety evaluation into target layers , criterion layer and factor layer, generate a dendrogram with target layer and criterion layer, criterion layer and factor layer as parent-child relationship, such as figure 1 shown;

[0037] ②Based on the analytic hi...

Abstract

The invention belongs to the technical field of dam safety reconnaissance, and discloses a comprehensive evaluation method for the dam safety. The method comprises the following steps that 1, a hierarchical structure model of a dam safety system is constructed to generate a tree diagram which takes an objective layer and a criterion layer as a father-son relationship and takes the criterion layer and a factor layer as a father-son relationship; 2, weights of all factors are obtained on the basis of an analytic hierarchy process; 3, objective weight values of all the factors are obtained on the basis of an entropy weight method; 4, a comprehensive weight of indexes is calculated; 5, the evaluation conclusion membership degree is judged; 6, comprehensive evaluation is performed on the dam properties. According to the comprehensive evaluation method for the dam safety, expert knowledge, engineering experiences and measurement data can be utilized more fully, and the dam working properties can be analyzed and evaluated more comprehensively and thoroughly; in addition, an algorithm is clear, easy to achieve and good in robustness, and the method can serve as a more reliable decision aid mean in dam safety management.

Description

technical field [0001] The invention belongs to the technical field of dam safety survey, and in particular relates to a comprehensive evaluation method for dam safety. Background technique [0002] At present, my country's dam safety monitoring is generally in a special stage. Many old dams are about to reach the design reference period, and a large number of new dams are being put into operation. In order to ensure the normal operation of the dam, in addition to strengthening daily inspections and monitoring, it is also necessary to conduct a comprehensive evaluation of the dam safety. The comprehensive evaluation of dam safety is a complex evaluation process affected by many factors, and there are not only hierarchical relationships among the factors, but also randomness and ambiguity. [0003] At present, the common dam safety evaluation methods in the industry, such as expert analysis method, gray evaluation method, etc., contain more qualitative indicators, and there ...
