Dam risk removal and reinforcement benefit post evaluation method based on improved cloud model

Abstract

The invention discloses a post-evaluation method for benefits of dam danger elimination and reinforcement based on an improved cloud model, and belongs to the technical field of reservoir dam danger elimination and reinforcement benefit evaluation. It includes the following steps: Step 1, obtain the relevant index data after the reinforcement of the dams to be studied, and build a post-evaluation system for the benefits of reinforcement of the reservoir dams; Step 2, formulate according to the requirements of different reservoir dams and the development situation of each region For the corresponding expected value, standardize each index value and expected value to improve the universality of the system, and determine the evaluation level and standard of the comprehensive benefit of dam danger reduction and reinforcement; Step 3, calculate the projected value obtained by the projection pursuit method and the entropy weight method The objective weight is coupled with the initial weight calculated by the cloud model, and the index weight is calculated by the combination evaluation method; step 4, the index membership degree is calculated by the conditional cloud generator, and the evaluation level is judged by the confidence criterion evaluation method to obtain the evaluation value of each index and Comprehensive evaluation level. The invention provides a basis for engineering management.

Description

technical field [0001] The invention relates to a post-evaluation method for the benefit of dam danger elimination and reinforcement based on an improved cloud model, and belongs to the technical field of reservoir dam danger elimination and reinforcement benefit evaluation. Background technique [0002] my country has a total of 98,002 reservoirs with a total storage capacity of 932.312 billion m 3 , Reservoirs play a huge role in flood control, power generation, water supply, etc. At present, the relevant risk reduction and reinforcement work of reservoir dams in various places has been carried out one after another. Therefore, it is necessary to re-evaluate the projects that have been completed for risk removal and reinforcement, and to further improve the reservoirs that do not meet the evaluation requirements. [0003] The post-evaluation of the benefits of dam treatment can be used as an engineering basis and has certain guiding significance. It is also the premise a...
