Abstract

The invention relates to a bridge maintenance decision-making method based on a dynamic programming method, and the method comprises the following steps: obtaining the comprehensive deducted score of m types of components based on the deducted score of m types of components of a bridge, the weight of an inspection item, and the weight of an inspection component, and m is the total number of divided component types of the bridge; obtaining comprehensive maintenance cost of various components of the bridge; establishing a maintenance income matrix of the bridge based on the maintenance fund of the bridge unit, the comprehensive deducted score of each component, the comprehensive maintenance cost and the maintenance reduction coefficient; and dividing the total amount of bridge maintenance funds into m stages for distribution, establishing a bridge dynamic planning basic equation and a first boundary condition, and solving and obtaining an optimal distribution sequence when the total amount of bridge maintenance funds is distributed to m types of components in combination with the maintenance income matrix of the bridge. According to the method, the bridge maintenance work can be better completed under the condition of limited resources.

Description

technical field [0001] This application relates to the technical field of bridge engineering management, maintenance and repair, in particular to a bridge maintenance decision-making method based on a dynamic programming method. Background technique [0002] In recent years, as the service time of urban bridges has increased year by year, the phenomenon of vehicle overloading on bridges has frequently occurred, and some bridges that have been in service for a long time or even newly built bridges have begun to have problems with increased disease development. If it cannot be repaired in time, it will lead to rapid deterioration of the disease and eventually lead to bridge safety accidents. [0003] At the same time, with the continuous increase of urban traffic demand, the number of urban bridges is increasing year by year, and the number of bridges that need to be managed and maintained is also increasing. Bridges are composed of various components, and their maintenance wo...
