Comprehensive evaluation method for water gate engineering health diagnosis

Abstract

According to the comprehensive evaluation method for water gate engineering health diagnosis, a subjective weighting method and an objective weighting method are fused, so that a weight calculation result is more reasonable and reliable, and the comprehensive evaluation method is combined with a water gate health diagnosis matter-element model based on quaternary correlates to form a complete evaluation system. Through the water gate health diagnosis matter-element model based on the quaternary connection number, the health state of the water gate is accurately reflected, the health state to which each diagnosis index belongs can also be well reflected, so that a good basis can be provided for maintenance and reinforcement, and meanwhile, the development trend of the health state of the water gate can be obtained through the connection potential. The calculation result of the comprehensive connection potential also intuitively reflects the health state of the water gate.

Description

technical field [0001] The invention relates to the field of water conservancy projects, in particular to a comprehensive evaluation method for health diagnosis of sluice projects. Background technique [0002] Water conservancy is the foundation of the national economy, and sluices are important hydraulic structures. As an important guarantee for sustainable economic and social development, sluices play an important role in industrial and agricultural production, water supply, flood control, tide protection and drainage. However, because most of the sluices were built in the 1950s and 1960s, and due to the constraints of the economy and technology at that time, unreasonable design, limited construction technology, improper or even lack of maintenance measures in the later period, the sluice Many problems occurred, such as the aging of the metal structure and the corrosion of the hoist, and the strength of the concrete continued to decrease and even did not meet the requirem...

AI Technical Summary

Problems solved by technology

However, because most of the sluices were built in the 1950s and 1960s, and due to the constraints of the economy and technology at that time, unreasonable design, limited construction technology, improper or even lack of maintenance measures in the later period, the sluice Many problems occurred, such as the aging of the metal structure and the corrosion of the hoist, the strength of the concrete continued to decrease and even did not meet the requirements of the current code, etc.

In addition, in recent years, more and more frequent extreme weather and natural disasters, such as heavy rain, snow disasters, earthquakes, etc., have made the environment of the sluice worse.

The joint influence of internal and external factors accelerated the destruction of the sluice
