Abstract

The invention provides a gravitational dam risk assessment calculation method based on analytic hierarchy process and fuzzy comprehensive evaluation. The method comprises the following steps: designing a gravitational dam, including drawing up the profile of the gravitational dam, calculating the load of the gravitational dam, analyzing the stability of the gravitational dam, and analyzing the stress of the gravitational dam; and performing risk assessment on the gravity dam by performing risk estimation on the gravity dam, establishing fuzzy comprehensive evaluation on risk factors, performing risk evaluation on gravity dam engineering, and analyzing a risk evaluation result of the gravity dam engineering. The step of performing risk estimation on the gravity dam further comprises the following steps of performing fuzzy estimation on risk probability and establishing a risk evaluation standard.

Description

technical field [0001] The invention relates to the technical field of data analysis, in particular to a gravity dam risk assessment calculation method based on hierarchical analysis and fuzzy comprehensive evaluation. Background technique [0002] With the scale development of my country's water conservancy construction and more risks in the process of project construction, the research on risk assessment of water conservancy projects is very important and necessary. In the design stage of the gravity dam, although the anti-sliding stability analysis and stress analysis are satisfied, due to various risk factors in the construction and operation stages, it cannot be considered that the dam can operate safely. It is very necessary and meaningful to identify the factors, calculate the size of the risk loss, and propose corresponding measures to deal with the risk. [0003] After the gravity dam meets the stability and strength requirements, it cannot be considered completely...
