Problems solved by technology

[0003] my country has made great progress in reservoir and dam safety evaluation technology, but there are still some problems: the relevant technical specification system has not yet been formed, and there is no detailed guidance on how to conduct online comprehensive evaluation based on dam body safety monitoring
In terms of dam safety evaluation, there is no unified technical standard in my country, so it is urgent to study a general and effective method for dam safety evaluation.

Abstract

The invention relates to a dam safety evaluation method based on monitored data, which belongs to the technical field of a hydropower project. According to the method of the invention, through building a dam safety evaluation model and a safety evaluation set, a statistical model method, a total duration characteristic value, a rate duration characteristic value, a calculation result comparison method, an engineering analogy method and a standard allowable value method are used for comprehensively analyzing a monitored value, and then, according to the evaluation result, an analytic hierarchy process and fuzzy evaluation are used for calculating the safety state of the dam. The safety state of the dam can be analyzed and evaluated in a real-time and dynamic mode, the safety state of the dam can be obtained quickly, the dam evaluation time is shortened greatly, the evaluation cost is reduced and a profound impact is exerted on the hydropower industry.

Description

technical field [0001] The invention belongs to the technical field of hydropower engineering, and in particular relates to a dam safety evaluation method based on monitoring data. Background technique [0002] In recent years, my country's hydropower development has been particularly rapid. A number of high dams represented by the Three Gorges Dam (dam height 181m), Jinsha River Xiluodu Arch Dam (dam height 285.5m), and Lancang River Xiaowan Arch Dam (dam height 294.5m) Large dams have been built one after another. With the continuous increase of dam height, the consequences of accidents will be serious. How to effectively evaluate the safety of dams based on monitoring data is a problem worthy of further study. [0003] my country has made great progress in reservoir and dam safety evaluation technology, but there are still some problems: the relevant technical specification system has not yet been formed, and there is no detailed guidance on how to conduct online comprehen...
