Embodiment Construction

[0087] The content of the present invention will be described below in conjunction with specific embodiments.

[0088] The earth-rock dam safety information mining method of the present invention establishes a data warehouse, performs data generalization, association rule mining, classification and cluster analysis on the earth-rock dam monitoring data, and excavates safety information such as individual characteristics and abnormal conditions of the earth-rock dam. The earth-rock dam safety information mining method of the present invention consists of establishing a data warehouse (data warehouse mode, data extraction conversion loading, online analysis operation), data generalization (attribute-oriented generalization, generalized representation), association rule mining (intra-item association rule mining, association rule mining between items), classification (decision tree classification, naive Bayesian classification, backward propagation classification), cluster analysi...

Abstract

The invention discloses an earth and rockfill dam safety information mining method. The method comprises the following steps of (1) establishing a data warehouse; Step (2), performing data generalization; Step (3), peforming association rule mining; Step (4): performing classifying; And (5) performing clustering analysis. By establishing the data warehouse, the earth and rockfill dam monitoring data is subjected to data generalization, association rule mining, classification and clustering analysis, safety information such as earth and rockfill dam individual characteristics and abnormal conditions is mined, and the actual use requirement is met.

Description

technical field [0001] The invention relates to an earth-rock dam safety information mining method, belonging to the technical field of information data mining. Background technique [0002] Reservoir dams are an important infrastructure of the national economy, an important engineering measure to regulate the temporal and spatial distribution of water resources and optimize the allocation of water resources, and an important part of the national flood control and drought relief system and the river flood control engineering system. Reservoir and dam safety is not only related to flood control safety, water supply safety, food safety, but also to economic safety, ecological safety and national security. Among the more than 90,000 reservoirs in my country, earth-rock dams account for the vast majority, and most of them were built in the 1950s and 1970s. Restricted by economic and technical conditions at the time, these earth-rock dams generally had problems such as low flood...
