Problems solved by technology

[0006] At present, there are few researches on road network level bridge management.
In actual bridge management work, managers generally only pay attention to the economics of bridge maintenance plans, and only rely on experience for technical considerations, without reasonable consideration of technical and economic aspects, and management work and data processing lack certain objectivity and scientificity

Embodiment Construction

[0046] Such as figure 1 As shown, a method for determining the maintenance priority of concrete bridges in the expressway network includes the following steps:

[0047] 1), establish an information system S for bridge management; S=(U,A,V,f), wherein: U is the domain of discourse, U=(u 1 , u 2 ,...,u i ), u i Indicates the i-th bridge; A is the attribute set of factors affecting the overall condition of the bridge, A={a 1 ,a 2 ,...,a j}, where j is the jth property of the bridge, j=1,2,...,5, a 1 Indicates the technical status of the bridge, a 2 Indicates the safety of the bridge, a 3 Indicates the bridge durability, a 4 Indicates bridge adaptability, a 5 Represents bridge economics; V represents the union of all attribute value ranges, v a Indicates the attribute value range of a certain attribute a∈A; f is an information function, f:U×A→V, used to determine the information value of each attribute in the attribute value range;

[0048] 2) Data discretization: di...

Abstract

The invention belongs to the field of bridge maintenance, and in particular relates to a method for determining the maintenance priority of concrete bridges in a highway network. The technical scheme of the present invention is as follows: comprise the following steps: 1), establish the information system S of bridge management; 2), data discretization: carry out discretization according to the interval that each property continuous numerical value of bridge provides; 3), rough set synthesis Evaluation: Calculate the importance weight ω of each attribute j and the comprehensive evaluation value K of each bridge i ; Subsequently, the comprehensive evaluation value is subjected to vector normalization processing, and the comprehensive evaluation value K of each bridge after normalization processing is obtained i ’; finally according to the K of each bridge i ’ value to determine the priority order of concrete bridge maintenance in the expressway network; 4) Establish an optimization model for decision-making results. The invention can combine the engineering experience of experts in the field of bridge maintenance and the mathematical analysis knowledge of engineering economics to rationally and scientifically formulate the bridge maintenance plan in the road network.

Description

technical field [0001] The invention belongs to the field of bridge maintenance, and in particular relates to a method for determining the maintenance priority of concrete bridges in a highway network. Background technique [0002] Bridge maintenance decision-making is to analyze and summarize emerging problems based on various data and information, rationally allocate limited maintenance funds and other resources, and determine the best strategy, plan and fund allocation for minor repairs and major and medium repairs for daily bridge maintenance. According to the core content of the decision-making, and according to different management objectives, bridge maintenance management decision-making can be divided into road network level and project level. [0003] Road network-level maintenance decision-making is aimed at a road and bridge network or all bridges in a road network under the jurisdiction of a management unit, formulating maintenance plans for bridges in the area, ...
